Message-ID: <20200916150147.25753-1-narmstrong@baylibre.com> (raw)
The T820, G31 & G52 GPUs integrated by Amlogic in the respective GXM, G12A/SM1 & G12B
SoCs needs a quirk in the PWR registers at the GPU reset time.
This serie adds the necessary quirks for the Amlogic integrated GPUs only.
Changes since v1 at [1]:
- removed the BROKEN_SH quirk after [2] was sent by robin
- rebased on top of [3] by steven and moved the vendor quirk in the proper quirk function
- added PWR_KEY unlock definition, and cleaned definition
