From cad7c46ae2d75b42aa8f1e3f741b203ed796eee9 Mon Sep 17 00:00:00 2001 From: Luca Weiss Date: Mon, 2 Oct 2023 14:30:41 +0200 Subject: [PATCH] arm64: dts: qcom: qcm6490-fairphone-fp5: Enable UFS Enable the UFS phy and controller so that we can access the internal storage of the phone. At the same time we need to bump the minimum voltage used for UFS VCC, otherwise it doesn't initialize properly. The 2.952V is taken from the vcc-voltage-level property downstream.
