Devicetree updates for v5.18: 

- Add Krzysztof Kozlowski as co-maintainer for DT bindings providing
   much needed help.
 
 - DT schema validation now takes DTB files as input rather than
   intermediate YAML files. This decouples the validation from the source
   level syntax information. There's a bunch of schema fixes as a result
   of switching to DTB based validation which exposed some errors
   and incomplete schemas and examples.
 
 - Kbuild improvements to explicitly warn users running 'make
   dt_binding_check' on missing yamllint
 
 - Expand DT_SCHEMA_FILES kbuild variable to take just a partial filename
   or path instead of the full path to 1 file.
 
 - Convert various bindings to schema format: mscc,vsc7514-switch,
   multiple GNSS bindings, ahci-platform, i2c-at91, multiple UFS
   bindings, cortina,gemini-sata-bridge, cortina,gemini-ethernet, Atmel
   SHA, Atmel TDES, Atmel AES, armv7m-systick, Samsung Exynos display
   subsystem, nuvoton,npcm7xx-timer, samsung,s3c2410-i2c, zynqmp_dma,
   msm/mdp4, rda,8810pl-uart
 
 - New schemas for u-boot environment variable partition, TI clksel
 
 - New compatible strings for Renesas RZ/V2L SoC
 
 - Vendor prefixes for Xen, HPE, deprecated Synopsys, deprecated HiSilicon
 
 - Add/fix schemas for QEMU Arm 'virt' machine
 
 - Drop unused of_alias_get_alias_list() function
 
 - Add a script to check DT unittest EXPECT message output. Pass messages
   also now print by default at PR_INFO level to help test automation.

* QEMU Firmware Configuration bindings for ARM
QEMU's arm-softmmu and aarch64-softmmu emulation / virtualization targets
provide the following Firmware Configuration interface on the "virt" machine
type:
- A write-only, 16-bit wide selector (or control) register,
- a read-write, 64-bit wide data register.
QEMU exposes the control and data register to ARM guests as memory mapped
registers; their location is communicated to the guest's UEFI firmware in the
DTB that QEMU places at the bottom of the guest's DRAM.
The authoritative guest-side hardware interface documentation to the fw_cfg
device can be found in "docs/specs/fw_cfg.txt" in the QEMU source tree.
Required properties:
- compatible: "qemu,fw-cfg-mmio".
- reg: the MMIO region used by the device.
* Bytes 0x0 to 0x7 cover the data register.
* Bytes 0x8 to 0x9 cover the selector register.
* Further registers may be appended to the region in case of future interface
revisions / feature bits.
Example:
/ {
#size-cells = <0x2>;
#address-cells = <0x2>;
fw-cfg@9020000 {
compatible = "qemu,fw-cfg-mmio";
reg = <0x0 0x9020000 0x0 0xa>;

* AHCI SATA Controller
SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.
It is possible, but not required, to represent each port as a sub-node.
It allows to enable each port independently when dealing with multiple
PHYs.
Required properties:
- compatible : compatible string, one of:
- "brcm,iproc-ahci"
- "hisilicon,hisi-ahci"

description: |
SATA nodes are defined to describe on-chip Serial ATA controllers.
Each SATA controller should have its own node.
It is possible, but not required, to represent each port as a sub-node.
It allows to enable each port independently when dealing with multiple

* Cortina Systems Gemini SATA Bridge
The Gemini SATA bridge in a SoC-internal PATA to SATA bridge that
takes two Faraday Technology FTIDE010 PATA controllers and bridges
them in different configurations to two SATA ports.
Required properties:
- compatible: should be
"cortina,gemini-sata-bridge"
- reg: registers and size for the block
- resets: phandles to the reset lines for both SATA bridges
- reset-names: must be "sata0", "sata1"
- clocks: phandles to the compulsory peripheral clocks
- clock-names: must be "SATA0_PCLK", "SATA1_PCLK"
- syscon: a phandle to the global Gemini system controller
- cortina,gemini-ata-muxmode: tell the desired multiplexing mode for
the ATA controller and SATA bridges. Values 0..3:
Mode 0: ata0 master <-> sata0
ata1 master <-> sata1
ata0 slave interface brought out on IDE pads
Mode 1: ata0 master <-> sata0
ata1 master <-> sata1
ata1 slave interface brought out on IDE pads
Mode 2: ata1 master <-> sata1
ata1 slave <-> sata0
ata0 master and slave interfaces brought out
on IDE pads
Mode 3: ata0 master <-> sata0
ata0 slave <-> sata1
ata1 master and slave interfaces brought out
on IDE pads
Optional boolean properties:
- cortina,gemini-enable-ide-pins: enables the PATA to IDE connection.
The muxmode setting decides whether ATA0 or ATA1 is brought out,
and whether master, slave or both interfaces get brought out.
- cortina,gemini-enable-sata-bridge: enables the PATA to SATA bridge
inside the Gemnini SoC. The Muxmode decides what PATA blocks will
be muxed out and how.
Example:
sata: sata@46000000 {
compatible = "cortina,gemini-sata-bridge";
reg = <0x46000000 0x100>;
resets = <&rcon 26>, <&rcon 27>;

Device-Tree bindings for Samsung Exynos SoC mobile image compressor (MIC)
MIC (mobile image compressor) resides between decon and mipi dsi. Mipi dsi is
not capable to transfer high resoltuion frame data as decon can send. MIC
solves this problem by compressing the frame data by 1/2 before it is
transferred through mipi dsi. The compressed frame data must be uncompressed in
the panel PCB.
Required properties:
- compatible: value should be "samsung,exynos5433-mic".
- reg: physical base address and length of the MIC registers set and system
register of mic.
- clocks: must include clock specifiers corresponding to entries in the
clock-names property.
- clock-names: list of clock names sorted in the same order as the clocks
property. Must contain "pclk_mic0", "sclk_rgb_vclk_to_mic0".
- samsung,disp-syscon: the reference node for syscon for DISP block.
- ports: contains a port which is connected to decon node and dsi node.
address-cells and size-cells must 1 and 0, respectively.
- port: contains an endpoint node which is connected to the endpoint in the
decon node or dsi node. The reg value must be 0 and 1 respectively.
Example:
SoC specific DT entry:
mic: mic@13930000 {
compatible = "samsung,exynos5433-mic";
reg = <0x13930000 0x48>;
clocks = <&cmu_disp CLK_PCLK_MIC0>,

Qualcomm adreno/snapdragon MDP4 display controller
Description:
This is the bindings documentation for the MDP4 display controller found in
SoCs like MSM8960, APQ8064 and MSM8660.
Required properties:
- compatible:
* "qcom,mdp4" - mdp4
- reg: Physical base address and length of the controller's registers.
- interrupts: The interrupt signal from the display controller.
- clocks: device clocks
See ../clocks/clock-bindings.txt for details.
- clock-names: the following clocks are required.
* "core_clk"
* "iface_clk"
* "bus_clk"
* "lut_clk"
* "hdmi_clk"
* "tv_clk"
- ports: contains the list of output ports from MDP. These connect to interfaces
that are external to the MDP hardware, such as HDMI, DSI, EDP etc (LVDS is a
special case since it is a part of the MDP block itself).
Each output port contains an endpoint that describes how it is connected to an
external interface. These are described by the standard properties documented
here:
Documentation/devicetree/bindings/graph.txt
Documentation/devicetree/bindings/media/video-interfaces.txt
The output port mappings are:
Port 0 -> LCDC/LVDS
Port 1 -> DSI1 Cmd/Video
Port 2 -> DSI2 Cmd/Video
Port 3 -> DTV
Optional properties:
- clock-names: the following clocks are optional:
* "lut_clk"
- qcom,lcdc-align-lsb: Boolean value indicating that LSB alignment should be
used for LCDC. This is only valid for 18bpp panels.
Example:
/ {
...
hdmi: hdmi@4a00000 {
...

...
port@0 {
reg = <0>;
hdmi_in: endpoint {
remote-endpoint = <&mdp_dtv_out>;

description: |
MIC (Mobile Image Compressor) resides between DECON and MIPI DSI. MIPI DSI is
not capable of transferring high resoltuion frame data as DECON can send. MIC
solves this problem by compressing the frame data by 1/2 before it is
transferred through MIPI DSI. The compressed frame data must be uncompressed
in the panel PCB.

GNSS Receiver DT binding
This documents the binding structure and common properties for GNSS receiver
devices.
A GNSS receiver node is a node named "gnss" and typically resides on a serial
bus (e.g. UART, I2C or SPI).
Please refer to the following documents for generic properties:
Documentation/devicetree/bindings/serial/serial.yaml
Documentation/devicetree/bindings/spi/spi-bus.txt
Required properties:
- compatible : A string reflecting the vendor and specific device the node
represents
Optional properties:
- lna-supply : Separate supply for an LNA
- enable-gpios : GPIO used to enable the device
- timepulse-gpios : Time pulse GPIO
Example:
serial@1234 {
compatible = "ns16550a";
gnss {
compatible = "u-blox,neo-8";
vcc-supply = <&gnss_reg>;
timepulse-gpios = <&gpio0 16 GPIO_ACTIVE_HIGH>;

The SiRFstar GNSS receivers have incarnated over the years in different
chips, starting from the SiRFstarIII which was a chip that was introduced in
2004 and used in a lot of dedicated GPS devices. In 2009 SiRF was acquired
by CSR (Cambridge Silicon Radio) and in 2012 the CSR GPS business was
acquired by Samsung, while some products remained with CSR. In 2014 CSR
was acquired by Qualcomm who still sell some of the SiRF products.

* Samsung's I2C controller
The Samsung's I2C controller is used to interface with I2C devices.
Required properties:
- compatible: value should be either of the following.
(a) "samsung, s3c2410-i2c", for i2c compatible with s3c2410 i2c.
(b) "samsung, s3c2440-i2c", for i2c compatible with s3c2440 i2c.
(c) "samsung, s3c2440-hdmiphy-i2c", for s3c2440-like i2c used
inside HDMIPHY block found on several samsung SoCs
(d) "samsung, exynos5-sata-phy-i2c", for s3c2440-like i2c used as
a host to SATA PHY controller on an internal bus.
- reg: physical base address of the controller and length of memory mapped
region.
- interrupts: interrupt number to the cpu.
- samsung,i2c-sda-delay: Delay (in ns) applied to data line (SDA) edges.
Required for all cases except "samsung,s3c2440-hdmiphy-i2c":
- Samsung GPIO variant (deprecated):
- gpios: The order of the gpios should be the following: <SDA, SCL>.
The gpio specifier depends on the gpio controller. Required in all
cases except for "samsung,s3c2440-hdmiphy-i2c" whose input/output
lines are permanently wired to the respective clienta
- Pinctrl variant (preferred, if available):
- pinctrl-0: Pin control group to be used for this controller.
- pinctrl-names: Should contain only one value - "default".
Optional properties:
- samsung,i2c-slave-addr: Slave address in multi-master environment. If not
specified, default value is 0.
- samsung,i2c-max-bus-freq: Desired frequency in Hz of the bus. If not
specified, the default value in Hz is 100000.
- samsung,sysreg-phandle - handle to syscon used to control the system registers
Example:
i2c@13870000 {
compatible = "samsung,s3c2440-i2c";
reg = <0x13870000 0x100>;
interrupts = <345>;
samsung,i2c-sda-delay = <100>;
samsung,i2c-max-bus-freq = <100000>;
/* Samsung GPIO variant begins here */
gpios = <&gpd1 2 0 /* SDA */
&gpd1 3 0 /* SCL */>;
/* Samsung GPIO variant ends here */
/* Pinctrl variant begins here */
pinctrl-0 = <&i2c3_bus>;
pinctrl-names = "default";
/* Pinctrl variant ends here */
#address-cells = <1>;
#size-cells = <0>;

Cortina Systems Gemini Ethernet Controller
==========================================
This ethernet controller is found in the Gemini SoC family:
StorLink SL3512 and SL3516, also known as Cortina Systems
CS3512 and CS3516.
Required properties:
- compatible: must be "cortina,gemini-ethernet"
- reg: must contain the global registers and the V-bit and A-bit
memory areas, in total three register sets.
- syscon: a phandle to the system controller
- #address-cells: must be specified, must be <1>
- #size-cells: must be specified, must be <1>
- ranges: should be state like this giving a 1:1 address translation
for the subnodes
The subnodes represents the two ethernet ports in this device.
They are not independent of each other since they share resources
in the parent node, and are thus children.
Required subnodes:
- port0: contains the resources for ethernet port 0
- port1: contains the resources for ethernet port 1
Required subnode properties:
- compatible: must be "cortina,gemini-ethernet-port"
- reg: must contain two register areas: the DMA/TOE memory and
the GMAC memory area of the port
- interrupts: should contain the interrupt line of the port.
this is nominally a level interrupt active high.
- resets: this must provide an SoC-integrated reset line for
the port.
- clocks: this should contain a handle to the PCLK clock for
clocking the silicon in this port
- clock-names: must be "PCLK"
