dm: regulator: add function device_get_supply_regulator()

2015-11-02T01:38:00Z

Some devices are supplied by configurable regulator's output. But there was no function for getting it. This commit adds function, that allows for getting the supply device by it's phandle. The returned regulator device can be used with regulator uclass's API. Signed-off-by: Przemyslaw Marczak Cc: Simon Glass Signed-off-by: Minkyu Kang

dm: pmic: add s2mps11 PMIC I/O driver

2015-11-02T01:38:00Z

This driver allows I/O operations on the Samsung S2MPS11 PMIC, which provides lots of LDO/BUCK outputs. To enable it, update defconfig with: - CONFIG_PMIC_S2MPS11 and additional, if were not defined: - CONFIG_CMD_PMIC - CONFIG_ERRNO_STR The binding info: doc/device-tree-bindings/pmic/s2mps11.txt Signed-off-by: Przemyslaw Marczak Reviewed-by: Simon Glass Tested-by: Anand Moon Signed-off-by: Minkyu Kang

sunxi: power: Change axp209 LDO3 and LDO4 default to disabled

2015-10-20T16:40:27Z

LDO3 and LDO4 are normally either unused, or used to power csi attached camera sensors, and as such do not need to be enabled at boot time. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Add support for disabling axp209 regulators

2015-10-20T16:40:27Z

Add support for disabling the regulators found on the axp209 pmic. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Drop protection against multiple calls from axp221 axp_init()

2015-10-20T16:40:27Z

The only thing axp221.c's axp_init() does which needs protection against multiple calls is calling pmic_bus_init, and pmic_bus_init() itself is already protected against being called multiple times. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Use pmic_bus functions for axp152 / axp209 driver

2015-10-20T16:40:27Z

Use the generic pmic_bus helpers for the axp152 / axp209 drivers, rather then having them define their own register read / write functions. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Change A23/A33 aldo1 default voltage to 3.0V

2015-10-20T16:40:27Z

On A23 / A33 boards aldo1 is used for VCC-IO and should be 3.0V, make this the default. Note that this does not cause any functional changes since all sun8i board defconfig-s already contained: CONFIG_AXP_ALDO1_VOLT=3000 . Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Change A23/A33 VDD-SYS default from 1.2V to 1.1V

2015-10-20T16:40:27Z

Change the axp223 dcdc2 / VDD-SYS default from 1.2V to 1.1V, 1.1V is the value recommended by Allwinner and is what most fex files specify. This has been tested on a number of A23/A33 tablets including on an A23 Ippo-q8h-v1.2 PCB tablet which has a fex file which specifies 1.2V (which is where our original 1.2V default comes from).

sunxi: power: Unify axp pmic function names

2015-10-20T16:40:27Z

Stop prefixing the axp functions for setting voltages, etc. with the model number, there ever is only one pmic driver built into u-boot, this allows simplifying the callers. Signed-off-by: Hans de Goede Acked-by: Ian Campbell

sunxi: power: Make all voltages configurable through Kconfig

2015-10-20T16:40:27Z

On boards with axp221/223 pmic-s we already allow configuring most voltages. Make the Kconfig options for these also apply to boards with axp152 / axp209 pmic-s and extend them to configure all voltages. The Kconfig defaults are chosen so that this commit does not introduce any functional changes. Signed-off-by: Hans de Goede Acked-by: Ian Campbell
