Subject: ARM: dts: apq8064: Add DT support for GSBI6 and for UART pin mux
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=86e252a4f850a525ad5514163e14a36f1f1d19a4;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git

ARM: dts: apq8064: Add DT support for GSBI6 and for UART pin mux

This change adds DT support for GSBI6 and muxes the gpio pins
as UART lines. Also defines a alias for serial port on these lines.
