[PATCH v5 0/9] Qualcomm PMIC fixes

[Caleb Connolly]

This series addresses some long-standing issues with the SPMI arb
driver, the PMIC, and the PMIC GPIO. It fixes compatibility with
upstream Linux devicetrees, and simplifies pwrkey/resin support by
rewriting the pon driver to be a button driver rather than a GPIO
driver.

Existing users are adjusted to use the new button driver in their
oard init code.

This series is based on the pinctrl [1] and clock [2] cleanup series.
There may be some DTS conflicts applying it standalone.
