Subject: [PATCH v2 01/16] dt-bindings: media: fsl-pxp: convert to yaml
Date: Fri, 13 Jan 2023 10:54:07 +0100	[thread overview]
Message-ID: <20230112-imx-pxp-v2-1-e2281da1db55@pengutronix.de> (raw)
In-Reply-To: <20230112-imx-pxp-v2-0-e2281da1db55@pengutronix.de>

Convert the bindings of the Freescale Pixel Pipeline to YAML.

The conversion drops the previously listed compatibles for several SoCs.
It is unclear, if the PXP on these SoCs is compatible to any of the PXPs
on the existing SoCs and would allow to reuse the already defined
compatibles. The missing compatibles should be brought back when the
support for the PXP on these SoCs is added.

Signed-off-by: Michael Tretter <m.tretter@pengutronix.de>

Changelog:

v2:

- add fsl,imx6sll-pxp and fsl,imx6sx-pxp compatibles
- restrict number of interrupts per variant
- cleanup syntax

-Freescale Pixel Pipeline
-========================
-
-The Pixel Pipeline (PXP) is a memory-to-memory graphics processing engine
-that supports scaling, colorspace conversion, alpha blending, rotation, and
-pixel conversion via lookup table. Different versions are present on various
-i.MX SoCs from i.MX23 to i.MX7.
-
-Required properties:
-- compatible: should be "fsl,<soc>-pxp", where SoC can be one of imx23, imx28,
-  imx6dl, imx6sl, imx6sll, imx6ul, imx6sx, imx6ull, or imx7d.
-- reg: the register base and size for the device registers
-- interrupts: the PXP interrupt, two interrupts for imx6ull and imx7d.
-- clock-names: should be "axi"
-- clocks: the PXP AXI clock
-
-Example:
-
-pxp@21cc000 {
-	compatible = "fsl,imx6ull-pxp";
-	reg = <0x021cc000 0x4000>;
-	interrupts = <GIC_SPI 8 IRQ_TYPE_LEVEL_HIGH>,
-		     <GIC_SPI 18 IRQ_TYPE_LEVEL_HIGH>;
-	clock-names = "axi";
-	clocks = <&clks IMX6UL_CLK_PXP>;
-};
