Subject: [PATCH v3 1/2] arm64: dts: qcom: sm8550: Add UFS host controller and phy nodes
Date:   Mon, 16 Jan 2023 16:09:59 +0200

Add UFS host controller and PHY nodes.

Signed-off-by: Abel Vesa <abel.vesa@linaro.org>
---

Changes since v2:
 * reversed phy clocks and changed their names to ref and ref_aux
 * dropped both address-cells and size-cells from phy node
 * dropped the extra newline
 * moved #clocks-cells above #phy-cells
 * dropped ranges property
 * renamed ufshc to ufs
 * replaced RPMH_LN_BB_CLK3 clock with TCSR_UFS_PAD_CLKREF_EN for the
   ufs host controller node
 * added required-opps property to the ufs host controller node
