| 1 | Chips&Media Coda multi-standard codec IP | ||
| 2 | ======================================== | ||
| 3 | |||
| 4 | Coda codec IPs are present in i.MX SoCs in various versions, | ||
| 5 | called VPU (Video Processing Unit). | ||
| 6 | |||
| 7 | Required properties: | ||
| 8 | - compatible : should be "fsl,<chip>-src" for i.MX SoCs: | ||
| 9 | (a) "fsl,imx27-vpu" for CodaDx6 present in i.MX27 | ||
| 10 | (b) "fsl,imx53-vpu" for CODA7541 present in i.MX53 | ||
| 11 | (c) "fsl,imx6q-vpu" for CODA960 present in i.MX6q | ||
| 12 | - reg: should be register base and length as documented in the | ||
| 13 | SoC reference manual | ||
| 14 | - interrupts : Should contain the VPU interrupt. For CODA960, | ||
| 15 | a second interrupt is needed for the MJPEG unit. | ||
| 16 | - clocks : Should contain the ahb and per clocks, in the order | ||
| 17 | determined by the clock-names property. | ||
| 18 | - clock-names : Should be "ahb", "per" | ||
| 19 | - iram : phandle pointing to the SRAM device node | ||
| 20 | |||
| 21 | Example: | ||
| 22 | |||
| 23 | vpu: vpu@63ff4000 { | ||
| 24 | compatible = "fsl,imx53-vpu"; | ||
| 25 | reg = <0x63ff4000 0x1000>; | ||
| 26 | interrupts = <9>; | ||
| 27 | clocks = <&clks 63>, <&clks 63>; | ||
| 28 | clock-names = "ahb", "per"; | ||
| 29 | iram = <&ocram>; | ||
| 30 | }; | ||
