platform. Audio system topology, clocking and power can all be
|
||||
controlled through the Lochnagar, allowing the device under test
|
||||
to be used in a variety of possible use cases.
|
||||
|
||||
Also see these documents for generic binding information:
|
||||
[1] GPIO : ../gpio/gpio.txt
|
||||
|
||||
And these for relevant defines:

- present-gpios : Host present line, indicating the presence of a
|
||||
host system, see [1]. This can be omitted if the present line is
|

Cirrus Logic Lochnagar Audio Development Board
|
||||
|
||||
Lochnagar is an evaluation and development board for Cirrus Logic
|
||||
Smart CODEC and Amp devices. It allows the connection of most Cirrus
|
||||
Logic devices on mini-cards, as well as allowing connection of
|
||||
various application processor systems to provide a full evaluation
|
||||
platform. Audio system topology, clocking and power can all be
|
||||
controlled through the Lochnagar, allowing the device under test
|
||||
to be used in a variety of possible use cases.
|
||||
|
||||
This binding document describes the binding for the regulator portion
|
||||
of the driver.
|
||||
|
||||
Also see these documents for generic binding information:
|
||||
[1] Regulator: ../regulator/regulator.txt
|
||||
|
||||
This binding must be part of the Lochnagar MFD binding:
|
||||
[2] ../mfd/cirrus,lochnagar.txt
|
||||
|
||||
Optional sub-nodes:
|
||||
|
||||
- VDDCORE : Initialisation data for the VDDCORE regulator, which
|
||||
supplies the CODECs digital core if it has no build regulator for that
|
||||
purpose.
|
||||
Required Properties:
|
||||
- compatible : One of the following strings:
|
||||
"cirrus,lochnagar2-vddcore"
|
||||
- SYSVDD-supply: Primary power supply for the Lochnagar.
|
||||
|
||||
- MICVDD : Initialisation data for the MICVDD regulator, which
|
||||
supplies the CODECs MICVDD.
|
||||
Required Properties:
|
||||
- compatible : One of the following strings:
|
||||
"cirrus,lochnagar2-micvdd"
|
||||
- SYSVDD-supply: Primary power supply for the Lochnagar.
|
||||
|
||||
- MIC1VDD, MIC2VDD : Initialisation data for the MICxVDD supplies.
|
||||
Required Properties:
|
||||
- compatible : One of the following strings:
|
||||
"cirrus,lochnagar2-mic1vdd", "cirrus,lochnagar2-mic2vdd"
|
||||
Optional Properties:
|
||||
- cirrus,micbias-input : A property selecting which of the CODEC
|
||||
minicard micbias outputs should be used, valid values are 1 - 4.
|
||||
- MICBIAS1-supply, MICBIAS2-supply: Regulator supplies for the
|
||||
MICxVDD outputs, supplying the digital microphones, normally
|
||||
supplied from the attached CODEC.
|
||||
|
||||
- VDD1V8 : Recommended fixed regulator for the VDD1V8 regulator, which supplies the
|
||||
CODECs analog and 1.8V digital supplies.
|
||||
Required Properties:
|
||||
- compatible : Should be set to "regulator-fixed"
|
||||
- regulator-min-microvolt : Should be set to 1.8V
|
||||
- regulator-max-microvolt : Should be set to 1.8V
|
||||
- regulator-boot-on
|
||||
- regulator-always-on
|
||||
- vin-supply : Should be set to same supply as SYSVDD
|
||||
|
||||
Example:
|
||||
|
||||
lochnagar {
|
||||
lochnagar-micvdd: MICVDD {
|
||||
compatible = "cirrus,lochnagar2-micvdd";
