Subject: [PATCH] arm64: dts: qcom: sm8250: Add TLMM pinctrl node
Date: Thu, 30 Apr 2020 11:17:16 -0700 [thread overview]
Message-ID: <20200430181716.3797842-1-bjorn.andersson@linaro.org> (raw)
Add the TLMM pinctrl node for SM8250 and reserve pins 28-31 and 40-43 on
the MTP as firmware does not allow Linux to touch these pins.
Signed-off-by: Bjorn Andersson <bjorn.andersson@linaro.org>
