Project Description

Due previous hackweek (https://hackweek.opensuse.org/projects/test-mainline-kernel-on-an-older-qualcomm-soc-msm89xx-explore-mainline-kernel-qualcomm-mainlining) both msm8994 angler and msm8992 bullhead are booting and due other activity (including my work) both have working SD card, but that's just start. Add support for other functionality.

Goal for this Hackweek

• There are still some memory issues for bullhead (SMEM, invalid patch: https://lore.kernel.org/linux-arm-msm/20230128055214.33648-1-jamiemdouglass@gmail.com/), fix them.
• Regulators support for angler (basic for other functionality)
• USB support for both angler and bullhead
• Haptics support (https://wiki.postmarketos.org/wiki/Haptics)
• Document on
