It only has 1 channel, instead of 4 channels supporting time-multiplexed BT.656 on the A31. Since the H3 is a reduced version, it cannot "fallback" to a compatible that implements more features than it supports. This series separates support for the H3 variant from the A31 variant. Patches 1 ~ 3 separate H3 CSI from A31 CSI in the bindings, driver, and device tree, respectively. Patch 4 adds a pinmux setting for the MCLK (master clock). Some camera sensors use the master clock from the SoC instead of a standalone crystal. Patches 5 and 6 are examples of using a camera sensor with an SBC. Since the modules are detachable, these changes should not be merged. They should be implemented as overlays instead. Please have a look. In addition, I found that the first frame captured seems to always be incomplete, with either parts cropped, out of position, or missing color components.
