Subject: [PATCH 6/6] arm64: dts: qcom: msm8916-samsung-a2015: Disable muic i2c pin bias
Date: Fri, 13 Nov 2020 22:59:17 +0500 [thread overview]
Message-ID: <20201113175917.189123-6-nikitos.tr@gmail.com> (raw)
In-Reply-To: <20201113175917.189123-1-nikitos.tr@gmail.com>
From: Nikita Travkin <nikitos.tr@gmail.com>
Some versions of the firmware leave i2c gpios in a wrong state.
Add pinctrl that disables pin bias since external pull-up resistors
are present.
Fixes: 1329c1ab0730 ("arm64: dts: qcom: Add device tree for Samsung Galaxy A3U/A5U")
