Display regression with 5.10 kernel #45

Closed xc-racer99 closed 2 years ago

xc-racer99 commented 3 years ago

I first noticed with 5.10 that the display has stopped working. Need to bisect to figure out why. 5.9-rc2 worked properly.

Bisected to commit 766c6b63aa044e84b045803b40b14754d69a2a1d

Looks like we have something wrong setup in our DTS.

Looks like we just need to drop spi-cs-high from the LCD one.

Fix will be merged in v5.18/19 (not sure which) and is marked for backporting.
