It looks to me as though the BRCMFMAC kernel config option needs to be enabled
to support the AP6256S? I don't see that being enabled, does it end up being
pulled in by default or as a result of the above two settings?

Oops, is enabling this RK3288 setting an oversight? Or is it needed for HDMI
on the RK3399?
