[PATCH 0/2] media: v4l2-cci/ov9282: support single-read I2C transactions

[Richard Leitner]

This series adds support for configuring transport-specific CCI regmap
behavior for I2C sensors, which is then used in the OV9282 driver to
force single-register read transactions.

The motivation for this change is that some OV9282 camera modules require
single-read I2C transactions to operate correctly. In particular, OV9282
modules from Vision Components return invalid data on multi-byte reads,
while switching the regmap to single-read transactions fixes the problem.

This series does not change the default behavior of existing CCI users.
Only ov9282 opts into single-read transactions.
