Subject: [PATCH v3 0/3] Add X-Powers AXP15060 PMIC support

This patch series adds support for the X-Powers AXP15060 PMIC, which is
a general purpose PMIC seen on different boards with different SOC.
This series were tested on Starfive Visionfive 2 board.

On this board, IRQ line from PMIC isn't connected so PEK function is
completely unable to use, so IRQ existence detection is added to patch 2
to avoid initialization failure.

Besides, its GPIO/LDO control logic is quite different from other chips
and is not easy to add support for it basing on existing axp20x GPIO
driver, so I didn't add support for it in this series. Maybe others
could do this.
