A lot of patching was necessary, see the merge request and device wiki page for details. Thanks to opendata26 for helping with the port. https://wiki.postmarketos.org/wiki/Google_Pixel_3_XL_(google-crosshatch) [skip ci]: this hits the compile timeout

Subject: [PATCH] sec_ts: disable touchscreen firmware upgrade
|
|
|
|
The firmware upgrade function causes two issues on postmarketOS:
|
|
|
|
- USB breaks if the driver is built directly into the kernel.
|
|
- 60 second boot delay if the driver is built as a module, then loaded
|
|
in the initramfs without the firmware file.
|
|
|
|
Disable the firmware upgrade functionality to avoid these problems.
|
|
|
|
This patch is based on TWRP's patch by bigbiff and SultanXDA:
