2023-12-06sunxi: H616: remove default AXP305 selectionAndre Przywara1-1/+0
The original H616 devices released about three years ago were typically paired with an X-Powers AXP305 PMIC. Newer devices uses the smaller AXP313, and there seem to be far more systems with this PMIC around now. Remove the default AXP305 selection for the H616 SoC from the Kconfig, and move the PMIC selection into the board defconfig files instead.

2023-11-12power: regulator: add AXP313 supportAndre Przywara2-0/+18
The X-Powers AXP313a is a small PMIC with just three buck converters and three LDOs, one of which is actually fixed (so not modelled here).

2023-11-12power: pmic: sunxi: add AXP313 SPL driverAndre Przywara3-2/+150
On boards using the AXP313 PMIC, the DRAM rail is often not setup correctly at reset time, so we have to program the PMIC very early in the SPL, before running the DRAM initialisation. Add a simple AXP313 PMIC driver that knows about DCDC2(CPU) and DCDC3(DRAM), so that we can bump up the voltage before the DRAM init.

2023-11-12sunxi: board: simplify early PMIC setup conditionsAndre Przywara1-1/+1
So far we have a convoluted #ifdef mesh that guards the early AXP PMIC setup in board.c. That combination of &&, || and negations is very hard to read, maintain and especially to extend. Fortunately we have those same conditions already modelled in the Kconfig file, so they are actually redundant. On top of that the real reason we have those preprocessor guards in the first place is about the symbols that are *conditionally* defined: without #ifdefs the build would break because of them being undefined for many boards. To simplify this, just change the guards to actually look at the symbols needed, so CONFIG_AXP_xxx_VOLT instead of CONFIG_AXPyyy_POWER. This drastically improves the readability of this code, and makes adding PMIC support a pure Kconfig matter. Doing this revealed one bug in Kconfig: there is no axp_set_dcdc4() for the AXP818, even though CONFIG_AXP_DCDC4_VOLT includes that PMIC. Since the AXP818 wasn't included when calling axp_set_dcdc4() in board.c, this wasn't an issue, but becomes one now, so also remove the AXP818 from the DCDC4 Kconfig symbol.

2023-10-07power: pmic: rk8xx: Fix power-on source check in SPLJonas Karlman1-7/+13
The commit 30975fb73d51 ("rockchip: Add option to prevent booting on power plug-in") introduce an option to prevent booting a device when the device was powered on due to power plug-in instead of pressing a power button. This feature works by checking the power-on source during PMIC probe and powers off the device if power-on source was power plug-in. This check currently runs very late at PMIC probe in U-Boot proper. Fix so that the power-on source check can work at probe time in SPL. Also enable probe after bind and remove the PMIC banner in SPL. With this we can use ROCKCHIP_RK8XX_DISABLE_BOOT_ON_POWERON and SPL_PMIC_RK8XX to power off the device very quickly after TPL instead of after TF-A and U-Boot proper has been loaded and run.
