[PATCH 4/8] arm64: dts: qcom: msm8916-motorola: Use UART1 console pinctrl

From: Stephan Gerhold
Date: Tue Apr 15 2025 - 09:54:14 EST


The Motorola MSM8916-based smartphones all use UART1 with 2 pins (TX, RX)
as debug UART console, so make use of the new &blsp_uart1_console_default
template. This applies the needed bias-pull-up to avoid garbage input,
bootph-all for U-Boot and avoids having to override the UART pins.
