Subject: [PATCH 2/6] arm64: dts: qcom: sm8250: Commonize PCIe pins
Date:   Wed, 16 Jun 2021 02:58:39 +0200
Message-Id: <20210616005843.79579-2-konrad.dybcio@somainline.org>
In-Reply-To: <20210616005843.79579-1-konrad.dybcio@somainline.org>

Commonize PCIe pins, along with pin definitions for PCIe-connected
MHI modem (not enabled by default, as it's useless on modem-less boards).

While at it, remove "output-low" from the RB5 board, as it's
not necessary - we already explicitly pull the perst pin low.
