[PATCH v2] arm64: dts: qcom: msm8916-samsung-fortuna: Add touchscreen

From: Raymond Hackley
Date: Tue Mar 12 2024 - 03:46:06 EST


From: Joe Mason <buddyjojo06@xxxxxxxxxxx>

Like msm8916-samsung-a3u-eur, the Grand Prime uses a Zinitix BT541
touchscreen. Add it together with the necessary fixed-regulator to the
device tree.

[Raymond: Move to fortuna-common. Use interrupts-extended]
