From 94262a18d74b85704a025855819582b5e256c8f0 Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Thu, 10 Nov 2022 16:15:06 +0100 Subject: [PATCH] arm64: dts: qcom: sm7225-fairphone-fp4: Enable SD card Fairphone 4 uses sdhc_2 for the SD card, configure the pins for it and enable it. The regulators which are exclusively used for SDHCI have their maximum voltage decreased to what downstream sets on the consumer side, like on many other platforms and allowed to set the load.
