[jstultz: Forward ported to mainline, changed to use register
names rather then hex values, and removed config values set by

Wouldn't these writes be needed by ADV751x chips too? These seem to
belong to the main ADV75xx regmap. These should probably be a separate
func in adv7511_audio.c or adv7511_drv.c, and it should be called in
adv7511_power_on, so that ADV751x chips can utilize this too.
Thanks,
Archit

ARRAY_SIZE(adv7533_cec_fixed_registers));
