Subject: [PATCH v3 1/2] arm64: dts: qcom: sm8550: Add UFS host controller and phy nodes
Add UFS host controller and PHY nodes.
Signed-off-by: Abel Vesa <abel.vesa@...aro.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
