Tue Apr 15 21:29:42 UTC 2025
Convert fsl-imx-drm.txt to yaml format and create 5 yaml files for
differences purpose.
Additional changes:
- add missed include file in examples.
- add clocks, clock-names for ipu.

-Freescale i.MX DRM master device
-================================
-
-The freescale i.MX DRM master device is a virtual device needed to list all
-IPU or other display interface nodes that comprise the graphics subsystem.
-
-Required properties:
-- compatible: Should be "fsl,imx-display-subsystem"
-- ports: Should contain a list of phandles pointing to display interface ports
- of IPU devices
-
-example:
-
-display-subsystem {
- compatible = "fsl,imx-display-subsystem";
- ports = <&ipu_di0>;
-};
-
-
-Freescale i.MX IPUv3
-====================
-
-Required properties:
-- compatible: Should be "fsl,<chip>-ipu" where <chip> is one of
- - imx51
- - imx53
- - imx6q
- - imx6qp
-- reg: should be register base and length as documented in the
- datasheet
-- interrupts: Should contain sync interrupt and error interrupt,
- in this order.
-- resets: phandle pointing to the system reset controller and
- reset line index, see reset/fsl,imx-src.txt for details
-Additional required properties for fsl,imx6qp-ipu:
-- fsl,prg: phandle to prg node associated with this IPU instance
-Optional properties:
-- port@[0-3]: Port nodes with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt.
- Ports 0 and 1 should correspond to CSI0 and CSI1,
- ports 2 and 3 should correspond to DI0 and DI1, respectively.
-
-example:
-
-ipu: ipu at 18000000 {
- #address-cells = <1>;
- #size-cells = <0>;
- compatible = "fsl,imx53-ipu";
- reg = <0x18000000 0x080000000>;
- interrupts = <11 10>;
- resets = <&src 2>;

- ipu_di0: port at 2 {
- reg = <2>;
-
- ipu_di0_disp0: endpoint {
- remote-endpoint = <&display_in>;
- };
- };
-};
-
-Freescale i.MX PRE (Prefetch Resolve Engine)
-============================================
-
-Required properties:
-- compatible: should be "fsl,imx6qp-pre"
-- reg: should be register base and length as documented in the
- datasheet
-- clocks : phandle to the PRE axi clock input, as described
- in Documentation/devicetree/bindings/clock/clock-bindings.txt and
- Documentation/devicetree/bindings/clock/imx6q-clock.yaml.
-- clock-names: should be "axi"
-- interrupts: should contain the PRE interrupt
-- fsl,iram: phandle pointing to the mmio-sram device node, that should be
- used for the PRE SRAM double buffer.
-
-example:
-
-pre at 21c8000 {
- compatible = "fsl,imx6qp-pre";
- reg = <0x021c8000 0x1000>;
- interrupts = <GIC_SPI 90 IRQ_TYPE_EDGE_RISING>;
- clocks = <&clks IMX6QDL_CLK_PRE0>;
- clock-names = "axi";
- fsl,iram = <&ocram2>;

-
-Freescale i.MX PRG (Prefetch Resolve Gasket)
-============================================
-
-Required properties:
-- compatible: should be "fsl,imx6qp-prg"
-- reg: should be register base and length as documented in the
- datasheet
-- clocks : phandles to the PRG ipg and axi clock inputs, as described
- in Documentation/devicetree/bindings/clock/clock-bindings.txt and
- Documentation/devicetree/bindings/clock/imx6q-clock.yaml.
-- clock-names: should be "ipg" and "axi"
-- fsl,pres: phandles to the PRE units attached to this PRG, with the fixed
- PRE as the first entry and the muxable PREs following.

- clock-names = "ipg", "axi";
- fsl,pres = <&pre1>, <&pre2>, <&pre3>;
-};
-
-Parallel display support
-========================
-
-Required properties:
-- compatible: Should be "fsl,imx-parallel-display"
-Optional properties:
-- interface-pix-fmt: How this display is connected to the
- display interface. Currently supported types: "rgb24", "rgb565", "bgr666"
- and "lvds666".
-- ddc: phandle describing the i2c bus handling the display data
- channel
-- port@[0-1]: Port nodes with endpoint definitions as defined in
- Documentation/devicetree/bindings/media/video-interfaces.txt.
- Port 0 is the input port connected to the IPU display interface,
- port 1 is the output port connected to a panel.
-
-example:
-
-disp0 {
- compatible = "fsl,imx-parallel-display";
- interface-pix-fmt = "rgb24";
-
- port at 0 {
- reg = <0>;
-
- display_in: endpoint {
