PS3, Line 9: For TP_EN has a abnormal peek pull high before BL_EN.
> TP_EN means Touch screen Enable. […]

can this be resolved by changing the ordering of the GPIOs and setting BL_EN in romstage? Because if this is a panel spec issue, it's likely going to affect more than just this board

Patchset:

PS3:
> the "generic.probed" register(s) set in devicetree on firmware-brya-14505. […]
