From: Chen-Yu Tsai <redacted> The CSI0 block in the Allwinner R40 SoC looks to be the same as the one in the A20. The register maps line up, and they support the same features. The R40 appears to support BT.1120 based on the feature overview, but it is not mentioned anywhere else. Also like the A20, the ISP is not mentioned, but the CSI special clock needs to be enabled for the hardware to function. The manual does state that the CSI special clock is the TOP clock for all CSI hardware, but currently no hardware exists for us to test if CSI1 also depends on it or not. Add a compatible string for the CSI0 block in the R40, with the A20 compatible string as a fallback.
