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:
sm6115p-lenovo-j606f.dtb: phy@4807000: 'vddp-ref-clk-supply' does not match any of the regexes: 'pinctrl-[0-9]+'
