openwrt/target/linux/generic/backport-6.1/887-v6.5-mfd-axp20x-Add-support-for-AXP192.patch
Chukun Pan 85b156c113 generic: 6.1: backport AXP PMIC support 
Backport AXP15060, AXP313a and AXP192 support.
The AXP15060 PMIC is used for starfive boards,
and the AXP313a PMIC is used for sunxi boards.
Remove conflicting patches from starfive target.

Subject: [PATCH] mfd: axp20x: Add support for AXP192
The AXP192 PMIC is similar to the AXP202/AXP209, but with different
regulators, additional GPIOs, and a different IRQ register layout.
