[PATCH 1/4] drm/vc4: Fix clock source for VEC PixelValve on BCM2711

From: Maxime Ripard
Date: Thu May 20 2021 - 11:04:04 EST


From: Mateusz Kwiatkowski <kfyatek+publicgit@xxxxxxxxx>

On the BCM2711 (Raspberry Pi 4), the VEC is actually connected to
output 2 of pixelvalve3.

NOTE: This contradicts the Broadcom docs, but has been empirically
tested and confirmed by Raspberry Pi firmware devs.
