Subject: [PATCH v2 2/3] arm64: dts: qcom: sm8250: Add SDHCI2 pinctrl
Date: Sat, 12 Jun 2021 21:23:57 +0200 [thread overview]
Message-ID: <20210612192358.62602-2-konrad.dybcio@somainline.org> (raw)
In-Reply-To: <20210612192358.62602-1-konrad.dybcio@somainline.org>
Add required pins for SDHCI2, so that the interface can work reliably.
The configuration comes from a MTP board, which conveniently means it's
going to be correct for the vast majority of phones (and other devices).
