[PATCH v2 4/6] media: mali-c55: Fix Iridix bypass macros

From: Jacopo Mondi

Date: Fri Mar 13 2026 - 10:57:21 EST


From: Daniel Scally <dan.scally@xxxxxxxxxxxxxxxx>

The Mali C55 Iridix block has a digital gain function and tone mapping
function, whose enablement is controlled by two different bits
in the BYPASS_3 register.

Unfortunately, the "Gain" and "Tonemap" bypass bit definitions are the
wrong way around. Swap them.
