The Qualcomm UFS phy switched from dedicated driver to QMP phy driver. Eventually the old driver was removed in commit 02dca8c981b5 ("phy: qcom: remove ufs qmp phy driver"). The original driver and its binding used vddp-ref-clk regulator supply, but the new one did not and left the supply unused. The Qualcomm UFS phy bindings were also migrated to newer ones and dropped support for vddp-ref-clk regulator in commit dc5cb63592bd ("dt-bindings: phy: migrate QMP UFS PHY bindings to qcom,sc8280xp-qmp-ufs-phy.yaml"). It turns out that this regulator, although with inaccurate name vddp-ref-clk, is actually needed to provide supply for VDD_PX10 (or similar, depending on the SoC) used by UFS controller. Bring back handling of this supply by using more appropriate regulator - UFS controller host supply. This also fixes dtbs_check warning: msm8996-oneplus3t.dtb: phy@627000: 'vddp-ref-clk-supply' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> --- arch/arm64/boot/dts/qcom/msm8996-oneplus-common.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-)
