Subject[PATCH 0/3] arm64: dts: qcom: sc8280xp: disallow regulator mode switches
Date
A recent change in a USB/DP PHY driver that started specifying regulator
loads caused the regulators that were also shared with the PCIe and USB
PHYs to be put in low-power mode, something which broke PCIe and USB on
sa8295p-adp.

As was discussed in the following thread:

https://lore.kernel.org/all/YtkrDcjTGhpaU1e0@hovoldconsulting.com

regulators should generally not be allowed to switch to low-power mode
unless some of the consumers can actually support an idle mode.

This series disables mode-switching for all regulators on sc8280xp-crd,
sc8280xp-lenovo-thinkpad-x13s and sa8295p-adp except for the ones used
by the UFS controllers which do support an idle mode.
