Subject: [PATCH 0474/1085] panel-sitronix-st7701: Fix panel prepare over SPI
|
|
|
|
A DSI write is issued in st7701_prepare even when the probed panel
|
|
runs on SPI. In practice, this results in a panic with the
|
|
vc4-kms-dpi-hyperpixel2r overlay active.
|
|
|
|
Perform the equivalent write over SPI in this case.
