[PATCH v3 1/2] arm64: dts: qcom: sm8550: Add UFS host controller and phy nodes

From: Abel Vesa
Date: Mon Jan 16 2023 - 09:26:59 EST


Add UFS host controller and PHY nodes.

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

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
