Subject: [PATCH v2] arm64: dts: imx8mq-kontron-pitx-imx8m: remove vqmmc-supply node
Date: Tue, 14 Sep 2021 09:26:28 +0200 [thread overview]
Message-ID: <20210914072627.24173-1-heiko.thiery@gmail.com> (raw)
The sw4 output (V_1V8_S0 voltage) from the PMIC is the main supply for
the 1V8 power domain. It is not only used as supply for the eMMC.
So this voltage can not be changed and is not allowed to switched off.
Therefore we do not want to provide this regulator to the SDHC driver to
control this voltage.
Fixes: 5dbadc848259 ("arm64: dts: fsl: add support for Kontron pitx-imx8m board")
