Subject: [PATCH] arm64: dts: qcom: msm8916-ufi: Fix sim card selection pinctrl
Date:   Wed,  1 Mar 2023 16:53:50 +0800
MIME-Version: 1.0
Content-Transfer-Encoding: 8bit
Precedence: bulk

The previous commit mistakenly introduced sim_ctrl_default as pinctrl,
this is incorrect, the interface for sim card selection varies between
different devices and should not be placed in the dtsi.

This commit selects external SIM card slot for ufi001c as default.
uf896 selects the correct SIM card slot automatically, thus does not need
this pinctrl node.

Fixes: faf69431464b ("arm64: dts: qcom: msm8916-thwc: Add initial device trees")
