[PATCH] media: dt-bindings: convert CODA VPU bindings to yaml

[Philipp Zabel <p.zabel@pengutronix.de>]

Convert to YAML, add missing "fsl,imx6dl-vpu", "cnm,coda960"
compatible, and specify the power-domain property for i.MX6.

-Chips&Media Coda multi-standard codec IP
-========================================
-
-Coda codec IPs are present in i.MX SoCs in various versions,
-called VPU (Video Processing Unit).
-
-Required properties:
-- compatible : should be "fsl,<chip>-src" for i.MX SoCs:
-  (a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27
-  (b) "fsl,imx51-vpu" for CodaHx4 present in i.MX51
-  (c) "fsl,imx53-vpu" for CODA7541 present in i.MX53
-  (d) "fsl,imx6q-vpu" for CODA960 present in i.MX6q
-- reg: should be register base and length as documented in the
-  SoC reference manual
-- interrupts : Should contain the VPU interrupt. For CODA960,
-  a second interrupt is needed for the MJPEG unit.
-- clocks : Should contain the ahb and per clocks, in the order
-  determined by the clock-names property.
-- clock-names : Should be "ahb", "per"
-- iram : phandle pointing to the SRAM device node
-
-Example:
-
-vpu: vpu@63ff4000 {
-	compatible = "fsl,imx53-vpu";
-	reg = <0x63ff4000 0x1000>;
-	interrupts = <9>;
-	clocks = <&clks 63>, <&clks 63>;
-	clock-names = "ahb", "per";
-	iram = <&ocram>;
-};
