[PATCH v2 02/15] drm/vc4: hdmi: Move hdmi reset to bind
From: Maxime Ripard <hidden>
Date: 2021-01-11 14:24:18
Also in:
dri-devel, linux-media, lkml
Subsystem:
drm drivers, drm drivers and misc gpu patches, drm drivers for vc4, the rest · Maintainers:

From: Dom Cobley <redacted>
The hdmi reset got moved to a later point in the commit 9045e91a476b
("drm/vc4: hdmi: Add reset callback").
However, the reset now occurs after vc4_hdmi_cec_init and so tramples
the setup of registers like HDMI_CEC_CNTRL_1
This only affects pi0-3 as on pi4 the cec registers are in a separate
block
Fixes: 9045e91a476b ("drm/vc4: hdmi: Add reset callback")
