Subject[PATCH 0/6] media: sun6i: Separate H3 compatible from A31
Date
The CSI (camera sensor interface) controller found on the H3 (and H5)
is a reduced version of the one found on the A31. 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.

Regards
ChenYu
