[PATCH 1/1] Revert "media: imx290: Convert to new CCI register access helpers"

From: Alexander Stein
Date: Wed Nov 01 2023 - 06:09:48 EST


cci_write() unconditionally writes multi-byte data in big-endian format.
But IMX290 and IMX327 use little-endian format for multi-byte registers.
Revert the CCI usage until little-endian is supported by CCI register
access helpers.
This reverts commit af73323b97702e53b0a336972aaf23e7dd92c850.

---
The difference is subtile, but imx290_write() uses put_unaligned_le24(),
while cci_write() uses put_unaligned_be24().

I assume this should go into stable as well. How to deal with that?
Shall a revert get the fixes tag as well?
