[PATCH v2 13/15] arm64: dts: qcom: msm8996: drop unsupported UFS vddp-ref-clk-max-microamp

From: Krzysztof Kozlowski <hidden>
Date: 2022-02-22 15:01:02
Also in: linux-arm-msm, linux-devicetree, linux-mediatek, linux-samsung-soc, linux-scsi, lkml
Subsystem: arm/qualcomm mailing list, arm/qualcomm support, the rest · Maintainers: Bjorn Andersson, Konrad Dybcio, Linus Torvalds

The property vddp-ref-clk-max-microamp (for VDDP ref clk supply which is
l25 regulator) is not documented in MSM8996 UFS PHY bindings
(qcom,msm8996-qmp-ufs-phy).  It is mentioned in the other UFS PHY
bindings for qcom,msm8996-ufs-phy-qmp-14nm.

The MSM8996-based Xiaomi devices configure l25 regulator in a
conflicting way:
1. with maximum 100 uAmp for VDDP ref clk supply of UFS PHY,
2. with maximum 450 mAmp for VCCQ supply of UFS.

Since the vddp-ref-clk-max-microamp property is basically not
documented for that UFS PHY and has a conflicting values, drop it
entirely as it looks like not tested and not used ever.
