2017-04-30power: Convert CONFIG_PMIC_AS3722 to KconfigSimon Glass
This converts the following to Kconfig: CONFIG_PMIC_AS3722 Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-30power: Move as3722 pmic to pmic/ directorySimon Glass
Most of the PMICs are in the drivers/power/pmic/ directory. Move this one there. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-30power: Rename CONFIG_AS3722_POWER to CONFIG_PMIC_AS3722Simon Glass
Before converting this to Kconfig, rename it to match the other PMICs. Signed-off-by: Simon Glass <sjg@chromium.org>
2017-04-28sunxi: power: Compile sy8106a driver only during SPL buildJernej Skrabec
Driver for that regulator is used only in SPL and it uses old I2C interface. If we want to use DM I2C in U-Boot proper, compilation of this driver has to be limited only to SPL.

2017-04-20sunxi: Enable AXP221s in I2C mode with the R40 SoCChen-Yu Tsai
The R40 SoC uses the AXP221s in I2C mode to supply power. Some regulator's common usages have changed, and also the recommended voltage for existing usages have changed. Update the defaults to match.

2017-04-05sunxi: prepare for sharing MACH_SUN8I_H3 config symbolAndre Przywara
The Allwinner H5 is very close to the H3 SoC, but has ARMv8 cores. To allow sharing the clocks, GPIO and driver code easily, create an architecture agnostic MACH_SUNXI_H3_H5 Kconfig symbol. Rename the existing symbol to MACH_SUNXI_H3_H5 where code is shared and let it be selected by a new shared Kconfig option.

2017-03-09sunxi: power: axp809.c: Fix aldo1-2 being disabled for mvolt != 0Rask Ingemann Lambertsen
The execution flow is currently like this for aldo_num == 1 or 2: int axp_set_aldo(int aldo_num, unsigned int mvolt) { ... if (mvolt == 0) return pmic_bus_clrbits(AXP809_OUTPUT_CTRL1, AXP809_OUTPUT_CTRL1_ALDO1_EN << (aldo_num - 1)); ... return pmic_bus_clrbits(AXP809_OUTPUT_CTRL1, AXP809_OUTPUT_CTRL1_ALDO1_EN << (aldo_num - 1)); } I.e. aldo1 and aldo2 will always be disabled. This patch fixes it by setting (rather than clearing) the enable bit when mvolt != 0.
