[PATCH 02/13] drm/i915/psr: Fix BDW PSR AUX CH data register offsets

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx>

The multiplication got replaced by an addition in some cleanup.
This means we never write the correct data to some of the BDW
PSR data registers and thus we fail to actually wake up the
panel from PSR.

Fixes: 4ab4fa103217 ("drm/i915/psr: Make PSR registers relative to transcoders")
