Try to fix Pinetab display issues #576

Open aqtrans opened 1 year ago

aqtrans commented 1 year ago

This includes the 0014-pinetab-dsi-from-raspeberrypi.patch from a postmarketOS MR to try and fix the same Pinetab display issues encountered in kernels 5.10+.

Trying it myself, it seems to solve them. I've fully shut off and powered it back on multiple times without any of the odd blank screen issues encountered before.

I noticed a Mobian MR open for this issue too, but this more minor patch seems to get my Pinetab going at least.

This should hopefully fix #370

I have a compiled version available for testing here, but note that I'd commented out the bootspash and dev-edition patches, as I seemingly had an unclean src/ (compiling with this PR, all patches applied without issue), but it is what I have been testing with.

@Danct12 I tested this and it works on SD card.

Nice, but please retain the commit author in the patch file. This is made sure so that the original code developer is being credited.

Ah yeah, that makes sense. Just updated the patchfile to include the full header.

None of this is needed. Just set this in the defconfig, problem is solved:

#  CONFIG_DRM_PANEL_FEIXIN_K101_IM2BA02 is not set
CONFIG_DRM_PANEL_ILITEK_ILI9881C=m
CONFIG_DRM_PANEL_SITRONIX_ST7703=m

It's just panicking on a race to basically boot the same driver. So turn of the redundant one, and make them modules instead of hard deps. The device will auto load them as needed.
