    Subject[PATCH 02/15] drm/vc4: hdmi: Move hdmi reset to bind
    Date
    From: Dom Cobley <popcornmix@gmail.com>

    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")
