[PATCH 0/2] phy: qcom: qmp-pcie: Add vdda-refgen supply support for Glymur

[Qiang Yu <qiang.yu@oss.qualcomm.com>]

The PCIe QMP PHYs on Glymur require both refgen for stable reference
voltage and qref for stable reference clock. The refgen requires two power
supplies: vdda-refgen0p9 and vdda-refgen1p2.

Unlike qref, refgen doesn't require register configuration and has no
dedicated driver. Therefore, the PHY driver must vote for the regulators
that refgen requires.

While refgen may be a common component across different platforms, on
older platforms it typically shares regulators with PHY core or qref
supplies, making refgen supplies map not very clear. Glymur introduces
dedicated refgen supplies that require explicit management.

Hence, this series adds support for refgen power supplies specifically to
Glymur PCIe QMP PHY. If other platforms require these supplies, support
can be extended in the future.

This series creates a Glymur-specific supply list including the refgen
supplies and updates both Gen5x4 and Gen4x2 configurations to use it.
