Staging / IIO driver patches for 5.11-rc1
Here is the big staging and IIO driver pull request for 5.11-rc1 Lots of different things in here: - loads of driver updates - so many coding style cleanups - new IIO drivers - Android ION code is finally removed from the tree - wimax drivers are moved to staging on their way out of the kernel Nothing really exciting, just the constant grind of kernel development :) All have been in linux-next for a while with no reported issues.

Bindings for ADC envelope detector using a DAC and a comparator
|
||||
|
||||
The DAC is used to find the peak level of an alternating voltage input
|
||||
signal by a binary search using the output of a comparator wired to
|
||||
an interrupt pin. Like so:
|
||||
_
|

||||
| | |
|
||||
| irq|------<-------'
|
||||
| |
|
||||
'-------'
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "axentia,tse850-envelope-detector"
|
||||
- io-channels: Channel node of the dac to be used for comparator input.
|
||||
- io-channel-names: Should be "dac".

The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
|

in some Mediatek SoCs which among other things measures the temperatures
|

in the SoC. It can be used directly with register accesses, but it is also
|
||||
used by thermal controller which reads the temperatures from the AUXADC
|
||||
directly via its own bus interface. See mediatek-thermal bindings
|

for the Thermal Controller which holds a phandle to the AUXADC.

* Mediatek AUXADC - Analog to Digital Converter on Mediatek mobile soc (mt65xx/mt81xx/mt27xx)
|
||||
===============
|
||||
|
||||
The Auxiliary Analog/Digital Converter (AUXADC) is an ADC found
|
||||
in some Mediatek SoCs which among other things measures the temperatures
|
||||
in the SoC. It can be used directly with register accesses, but it is also
|
||||
used by thermal controller which reads the temperatures from the AUXADC
|
||||
directly via its own bus interface. See
|
||||
Documentation/devicetree/bindings/thermal/mediatek-thermal.txt
|
||||
for the Thermal Controller which holds a phandle to the AUXADC.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be one of:
|
||||
- "mediatek,mt2701-auxadc": For MT2701 family of SoCs

|
||||
- "mediatek,mt8183-auxadc", "mediatek,mt8173-auxadc": For MT8183 family of SoCs
|
||||
- reg: Address range of the AUXADC unit.
|
||||
- clocks: Should contain a clock specifier for each entry in clock-names
|
||||
- clock-names: Should contain "main".
|
||||

Qualcomm's PM8xxx voltage XOADC
|
||||
|
||||
The Qualcomm PM8xxx PMICs contain a HK/XO ADC (Housekeeping/Crystal
|
||||
oscillator ADC) encompassing PM8018, PM8038, PM8058 and PM8921.
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: should be one of:
|
||||
"qcom,pm8018-adc"
|
||||
"qcom,pm8038-adc"
|
||||
"qcom,pm8058-adc"
|
||||
"qcom,pm8921-adc"
|
||||
|
||||
- reg: should contain the ADC base address in the PMIC, typically
|
||||
0x197.
|
||||
|
||||
- xoadc-ref-supply: should reference a regulator that can supply
|
||||
a reference voltage on demand. The reference voltage may vary
|
||||
with PMIC variant but is typically something like 2.2 or 1.8V.
|
||||
|
||||
The following required properties are standard for IO channels, see
|
||||
iio-bindings.txt for more details, but notice that this particular
|
||||
ADC has a special addressing scheme that require two cells for
|
||||
identifying each ADC channel:
|
||||
|
||||
- #address-cells: should be set to <2>, the first cell is the
|
||||
prescaler (on PM8058) or premux (on PM8921) with two valid bits
|
||||
so legal values are 0x00, 0x01 or 0x02. The second cell
|
||||
is the main analog mux setting (0x00..0x0f). The combination
|
||||
of prescaler/premux and analog mux uniquely addresses a hardware
|
||||
channel on all systems.
|
||||
|
||||
- #size-cells: should be set to <0>
|
||||
|
||||
- #io-channel-cells: should be set to <2>, again the cells are
|
||||
precaler or premux followed by the analog muxing line.
|
||||
|
||||
- interrupts: should refer to the parent PMIC interrupt controller
|
||||
and reference the proper ADC interrupt.
|
||||
|
||||
Required subnodes:
|
||||
|
||||
The ADC channels are configured as subnodes of the ADC.
|
||||
|
||||
Since some of them are used for calibrating the ADC, these nodes are
|
||||
compulsory:
|
||||
|
||||
adc-channel@c {
|
||||
reg = <0x00 0x0c>;
|
||||
};
|
||||
|
||||
adc-channel@d {
|
||||
reg = <0x00 0x0d>;
|
||||
};
|
||||
|
||||
adc-channel@f {
|
||||
reg = <0x00 0x0f>;
|
||||
};
|
||||
|
||||
These three nodes are used for absolute and ratiometric calibration
|
||||
and only need to have these reg values: they are by hardware definition
|
||||
1:1 ratio converters that sample 625, 1250 and 0 milliV and create
|
||||
an interpolation calibration for all other ADCs.
|
||||
|
||||
Optional subnodes: any channels other than channels [0x00 0x0c],
|
||||
[0x00 0x0d] and [0x00 0x0f] are optional.
|
||||
|
||||
Required channel node properties:
|
||||
|
||||
- reg: should contain the hardware channel number in the range
|
||||
0 .. 0xff (8 bits).
|
||||
|
||||
Optional channel node properties:
|
||||
|
||||
- qcom,decimation:
|
||||
Value type: <u32>
|
||||
Definition: This parameter is used to decrease the ADC sampling rate.
|
||||
Quicker measurements can be made by reducing the decimation ratio.
|
||||
Valid values are 512, 1024, 2048, 4096.
|
||||
If the property is not found, a default value of 512 will be used.
|
||||
|
||||
- qcom,ratiometric:
|
||||
Value type: <u32>
|
||||
Definition: Channel calibration type. If this property is specified
|
||||
VADC will use a special voltage references for channel
|

If the property is not found, the channel will be
|
||||

The reference voltage pairs when using ratiometric calibration:
|

* Renesas R-Car GyroADC device driver
|
||||
|
||||
The GyroADC block is a reduced SPI block with up to 8 chipselect lines,
|
||||
which supports the SPI protocol of a selected few SPI ADCs. The SPI ADCs
|
||||
are sampled by the GyroADC block in a round-robin fashion and the result
|
||||
presented in the GyroADC registers.
|
||||
|
||||
Required properties:
|
||||
- compatible: Should be "<soc-specific>", "renesas,rcar-gyroadc".
|
||||
The <soc-specific> should be one of:
|
||||
renesas,r8a7791-gyroadc - for the GyroADC block present
|
||||
in r8a7791 SoC
|
||||
renesas,r8a7792-gyroadc - for the GyroADC with interrupt
|
||||
block present in r8a7792 SoC
|
||||
- reg: Address and length of the register set for the device
|
||||
- clocks: References to all the clocks specified in the clock-names
|
||||
property as specified in
|
||||
Documentation/devicetree/bindings/clock/clock-bindings.txt.
|
||||
- clock-names: Shall contain "fck". The "fck" is the GyroADC block clock.
|
||||
- power-domains: Must contain a reference to the PM domain, if available.
|
||||
- #address-cells: Should be <1> (setting for the subnodes) for all ADCs
|
||||
except for "fujitsu,mb88101a". Should be <0> (setting for
|
||||
only subnode) for "fujitsu,mb88101a".
|
||||
- #size-cells: Should be <0> (setting for the subnodes)
|
||||
|
||||
Sub-nodes:
|
||||
You must define subnode(s) which select the connected ADC type and reference
|
||||
voltage for the GyroADC channels.
|
||||
|
||||
Required properties for subnodes:
|
||||
- compatible: Should be either of:
|
||||
"fujitsu,mb88101a"
|
||||
- Fujitsu MB88101A compatible mode,
|
||||
12bit sampling, up to 4 channels can be sampled in
|
||||
round-robin fashion. One Fujitsu chip supplies four
|
||||
GyroADC channels with data as it contains four ADCs
|
||||
on the chip and thus for 4-channel operation, single
|
||||
MB88101A is required. The Cx chipselect lines of the
|
||||
MB88101A connect directly to two CHS lines of the
|
||||
GyroADC, no demuxer is required. The data out line
|
||||
of each MB88101A connects to a shared input pin of
|
||||
the GyroADC.
|
||||
"ti,adcs7476" or "ti,adc121" or "adi,ad7476"
|
||||
- TI ADCS7476 / TI ADC121 / ADI AD7476 compatible mode,
|
||||
15bit sampling, up to 8 channels can be sampled in
|
||||
round-robin fashion. One TI/ADI chip supplies single
|
||||
ADC channel with data, thus for 8-channel operation,
|
||||
8 chips are required. A 3:8 chipselect demuxer is
|
||||
required to connect the nCS line of the TI/ADI chips
|
||||
to the GyroADC, while MISO line of each TI/ADI ADC
|
||||
connects to a shared input pin of the GyroADC.
|
||||
"maxim,max1162" or "maxim,max11100"
|
||||
- Maxim MAX1162 / Maxim MAX11100 compatible mode,
|
||||
16bit sampling, up to 8 channels can be sampled in
|
||||
round-robin fashion. One Maxim chip supplies single
|
||||
ADC channel with data, thus for 8-channel operation,
|
||||
8 chips are required. A 3:8 chipselect demuxer is
|
||||
required to connect the nCS line of the MAX chips
|
||||
to the GyroADC, while MISO line of each Maxim ADC
|
||||
connects to a shared input pin of the GyroADC.
|
||||
- reg: Should be the number of the analog input. Should be present
|
||||
for all ADCs except "fujitsu,mb88101a".
|
||||
- vref-supply: Reference to the channel reference voltage regulator.
|
||||
|
||||
Example:
|
||||
vref_max1162: regulator-vref-max1162 {
|

Current Sense Amplifier
|
||||
=======================
|
||||
|
||||
When an io-channel measures the output voltage from a current sense
|
||||
amplifier, the interesting measurement is almost always the current
|
||||
through the sense resistor, not the voltage output. This binding
|
||||
describes such a current sense circuit.
|
||||
|
||||
Required properties:
|
||||
- compatible : "current-sense-amplifier"
|
||||
- io-channels : Channel node of a voltage io-channel.
|
||||
- sense-resistor-micro-ohms : The sense resistance in microohms.
|
||||
|
||||
Optional properties:
|
||||
- sense-gain-mult: Amplifier gain multiplier. The default is <1>.
|
||||
- sense-gain-div: Amplifier gain divider. The default is <1>.
|
||||
|
||||
Example:
|
||||
|
||||
sysi {

Voltage divider

a curcuit.

Analog Devices AD5758 DAC device driver
|
||||
|
||||
Required properties for the AD5758:
|
||||
- compatible: Must be "adi,ad5758"
|
||||
- reg: SPI chip select number for the device
|
||||
- spi-max-frequency: Max SPI frequency to use (< 50000000)
|
||||
- spi-cpha: is the only mode that is supported
|
||||
|
||||
Required properties:
|
||||
|
||||
- adi,dc-dc-mode: Mode of operation of the dc-to-dc converter
|
||||
Dynamic Power Control (DPC)
|
||||
In this mode, the AD5758 circuitry senses the output
|
||||
voltage and dynamically regulates the supply voltage,
|
||||
VDPC+, to meet compliance requirements plus an optimized
|
||||
headroom voltage for the output buffer.
|
||||
|
||||
Programmable Power Control (PPC)
|
||||
In this mode, the VDPC+ voltage is user-programmable to
|
||||
a fixed level that needs to accommodate the maximum output
|
||||
load required.
|
||||
|
||||
The output of the DAC core is either converted to a
|
||||
current or voltage output at the VIOUT pin. Only one mode
|
||||
can be enabled at any one time.
|
||||
|
||||
The following values are currently supported:
|
||||
* 1: DPC current mode
|
||||
* 2: DPC voltage mode
|
||||
* 3: PPC current mode
|
||||
|
||||
Depending on the selected output mode (voltage or current) one of the
|
||||
two properties must
|
||||
be present:
|
||||
|
||||
- adi,range-microvolt: Voltage output range
|
||||
The array of voltage output ranges must contain two fields:
|
||||
* <0 5000000>: 0 V to 5 V voltage range
|
||||
* <0 10000000>: 0 V to 10 V voltage range
|
||||
* <(-5000000) 5000000>: ±5 V voltage range
|
||||
* <(-10000000) 10000000>: ±10 V voltage range
|
||||
- adi,range-microamp: Current output range
|
||||
The array of current output ranges must contain two fields:
|
||||
* <0 20000>: 0 mA to 20 mA current range
|
||||
* <0 24000>: 0 mA to 24 mA current range
|
||||
* <4 24000>: 4 mA to 20 mA current range
|
||||
* <(-20000) 20000>: ±20 mA current range
|
||||
* <(-24000) 24000>: ±24 mA current range
|
||||
* <(-1000) 22000>: −1 mA to +22 mA current range
|
||||
|
||||
Optional properties:
|
||||
|
||||
- reset-gpios : GPIO spec for the RESET pin. If specified, it will be
|
||||
asserted during driver probe.
|
||||
|
||||
- adi,dc-dc-ilim-microamp: The dc-to-dc converter current limit
|
||||
The following values are currently supported [uA]:
|
||||
* 150000
|
||||
* 200000
|
||||
* 250000
|
||||
* 300000
|
||||
* 350000
|
||||
* 400000
|
||||
|
||||
- adi,slew-time-us: The time it takes for the output to reach the
|
||||
full scale [uS]
|
||||
The supported range is between 133us up to 1023984375us
|
||||
|
||||
AD5758 Example:
|
||||
|
||||
dac@0 {
|
||||
compatible = "adi,ad5758";
|

Mode of operation of the dc-to-dc converter
|

Dynamic Power Control (DPC)
|
||||
In this mode, the AD5758 circuitry senses the output voltage and
|
||||
dynamically regulates the supply voltage, VDPC+, to meet compliance
|
||||
requirements plus an optimized headroom voltage for the output buffer.
|
||||
|
||||
Programmable Power Control (PPC)
|
||||
In this mode, the VDPC+ voltage is user-programmable to a fixed level
|
||||
that needs to accommodate the maximum output load required.
|
||||
|
||||
The output of the DAC core is either converted to a current or
|
||||
voltage output at the VIOUT pin. Only one mode can be enabled at
|
||||
any one time.
|
||||
|
||||
The following values are currently supported:
|
||||
* 1: DPC current mode
|
||||
* 2: DPC voltage mode
|
||||
* 3: PPC current mode

Optional properties (valid only for mcp4726):
|
||||
- vref-supply: Optional phandle to the Vref power supply. Vref pin is
|
||||
used as a voltage reference when this supply is specified.
|
||||
- microchip,vref-buffered: Boolean to enable buffering of the external
|
||||
Vref pin. This boolean is not valid without the vref-supply. Quoting
|
||||
the datasheet: This is offered in cases where the reference voltage
|
||||
does not have the current capability not to drop its voltage when
|
||||
connected to the internal resistor ladder circuit.
|
||||
|
||||

This binding is derived from clock bindings, and based on suggestions
|
||||
from Lars-Peter Clausen [1].
|
||||
|
||||
Sources of IIO channels can be represented by any node in the device
|
||||
tree. Those nodes are designated as IIO providers. IIO consumer
|
||||
nodes use a phandle and IIO specifier pair to connect IIO provider
|
||||
outputs to IIO inputs. Similar to the gpio specifiers, an IIO
|
||||
specifier is an array of one or more cells identifying the IIO
|
||||
output on a device. The length of an IIO specifier is defined by the
|
||||
value of a #io-channel-cells property in the IIO provider node.
|
||||
|
||||
[1] https://marc.info/?l=linux-iio&m=135902119507483&w=2
|
||||
|
||||
==IIO providers==
|
||||
|
||||
Required properties:
|
||||
#io-channel-cells: Number of cells in an IIO specifier; Typically 0 for nodes
|
||||
with a single IIO output and 1 for nodes with multiple
|
||||
IIO outputs.
|
||||
|
||||
Optional properties:
|
||||
label: A symbolic name for the device.
|
||||
|
||||
|
||||
Example for a simple configuration with no trigger:
|
||||
|
||||
adc: voltage-sensor@35 {
|
||||
compatible = "maxim,max1139";
|
||||
reg = <0x35>;
|
||||
#io-channel-cells = <1>;
|
||||
label = "voltage_feedback_group1";
|
||||
};
|
||||
|
||||
Example for a configuration with trigger:
|
||||
|
||||
adc@35 {
|
||||
compatible = "some-vendor,some-adc";
|
||||
reg = <0x35>;
|
||||
|
||||
adc1: iio-device@0 {
|
||||
#io-channel-cells = <1>;
|
||||
/* other properties */
|
||||
};
|
||||
adc2: iio-device@1 {
|
||||
#io-channel-cells = <1>;
|
||||
/* other properties */
|
||||
};
|
||||
};
|
||||
|
||||
==IIO consumers==
|
||||
|
||||
Required properties:
|
||||
io-channels: List of phandle and IIO specifier pairs, one pair
|
||||
for each IIO input to the device. Note: if the
|
||||
IIO provider specifies '0' for #io-channel-cells,
|
||||
then only the phandle portion of the pair will appear.
|
||||
|
||||
Optional properties:
|
||||
io-channel-names:
|
||||
List of IIO input name strings sorted in the same
|
||||
order as the io-channels property. Consumers drivers
|
||||
will use io-channel-names to match IIO input names
|
||||
with IIO specifiers.
|
||||
io-channel-ranges:
|
||||
Empty property indicating that child nodes can inherit named
|
||||
IIO channels from this node. Useful for bus nodes to provide
|
||||
and IIO channel to their children.
|
||||
|
||||
For example:
|
||||
|
||||
device {

Required properties:
|
||||
- compatible : should be one of
|
||||
"adi,ad5933"
|
||||
"adi,ad5934"
|
||||
- reg : the I2C address.
