Subject: [PATCH v1 2/2] arm64: dts: qcom: sc7180: trogdor: SD-card GPIO pin set bias-pull up
Date: Fri, 21 May 2021 13:05:29 -0700 [thread overview]
Message-ID: <20210521130511.v1.2.I52f30ddfe62041b7e6c3c362f0ad8f695ac28224@changeid> (raw)
In-Reply-To: <20210521200529.1991729-1-sujitka@chromium.org>
Trogdor board does not have external pull-up for cd-gpio. Set this pin
to internal pull-up for sleep config to avoid frequent regulator toggle
events.
This change is aligned with Qualcomm's DT change posted at:
