  Hi,

after the discussions at [1] and [2], this series adds proper support for
little-endian encoded registers.
Patch 1 adds the infrastructure and patch 2 fixes imx290 driver.
As v6.6 was released with imx290 broken, both should be added to stable.

Changes in v2:
* Add proper Fixes/CC tags to both patches
* Add little-endian support for cci_read()

Best regards,
Alexander
