From: Mateusz Kwiatkowski <redacted> 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. Signed-off-by: Mateusz Kwiatkowski <redacted> Signed-off-by: Maxime Ripard <redacted> --- drivers/gpu/drm/vc4/vc4_crtc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
