Subject: [RFT] arm64: ARM: dts: exynos: Remove double SD card detect pin inversion on TM2
Date: Fri, 21 Sep 2018 20:30:14 +0200 [thread overview]
Message-ID: <20180921183014.20236-1-krzk@kernel.org> (raw)
The SDHCI standard, MMC host controller bindings and MMC core defines
card detect pin as active low. Therefore there is no point to invert it
twice.
