dt-bindings: display: mxsfb: Convert binding to YAML
Convert the mxsfb binding to YAML. The deprecated binding is dropped, as neither the DT sources nor the driver support it anymore. The converted binding is named fsl,lcdif.yaml to match the usual bindings naming scheme. The compatible strings are messy, and DT sources use different kinds of combination of documented and undocumented values. Keep it simple for now, and update the example to make it valid. Aligning the binding with the existing DT sources will be performed separately.

* Freescale MXS LCD Interface (LCDIF)
|
||||
|
||||
New bindings:
|
||||
=============
|
||||
Required properties:
|
||||
- compatible: Should be "fsl,imx23-lcdif" for i.MX23.
|
||||
Should be "fsl,imx28-lcdif" for i.MX28.
|
||||
Should be "fsl,imx6sx-lcdif" for i.MX6SX.
|
||||
Should be "fsl,imx8mq-lcdif" for i.MX8MQ.
|
||||
- reg: Address and length of the register set for LCDIF
|
||||
- interrupts: Should contain LCDIF interrupt
|
||||
- clocks: A list of phandle + clock-specifier pairs, one for each
|
||||
entry in 'clock-names'.
|
||||
- clock-names: A list of clock names. For MXSFB it should contain:
|
||||
- "pix" for the LCDIF block clock
|
||||
- (MX6SX-only) "axi", "disp_axi" for the bus interface clock
|
||||
|
||||
Required sub-nodes:
|
||||
- port: The connection to an encoder chip.
|
||||
|
||||

|
||||
|
||||
lcdif1: display-controller@2220000 {
|
||||

|
||||
reg = <0x02220000 0x4000>;
|
||||
interrupts = <GIC_SPI 5 IRQ_TYPE_LEVEL_HIGH>;
|
||||
clocks = <&clks IMX6SX_CLK_LCDIF1_PIX>,
|
||||
<&clks IMX6SX_CLK_LCDIF_APB>,
|
||||
<&clks IMX6SX_CLK_DISPLAY_AXI>;
|
||||
clock-names = "pix", "axi", "disp_axi";

||||
|
||||

|
||||
parallel_out: endpoint {
|
||||
