2017-11-03MLK-16118-2 power: Add PD device lookup interface to power domain uclassYe Li
Add power_domain_lookup_name interface to power domain uclass to find a power domain device by its DTB node name, not using its associated client device. Through this interface, we can operate the power domain devices directly. This is needed for non-DM drivers. Reviewed-by: Peng Fan <peng.fan@nxp.com> Signed-off-by: Ye Li <ye.li@nxp.com>
2017-11-03MLK-16118-1 power: Add power domain driver for i.MX8QM/QXPYe Li
Add the power domain DM driver for i.MX8, that it depends on the DTB power domain trees to generate the power domain provider devices. Users needs add power domain trees with property "compatible = "nxp,imx8-pd";" - When power on one PD device, the driver will power on its ancestor PD devices in power domain tree. - When power off on PD device, the driver will check its child PD devices first, only all child PD devices are off, then power off the current PD device. Then the driver checks sibling PD devices. If sibling PD devices are off, then it will power off parent PD device. - There is no counter maintained in this driver, but a state to hold current on/off state. So the request and free functions are empty. - The power domain implemetation in i.MX8 DTB set the "#power-domain-cells" to 0, so there is no ID binding with each PD device. We don't use "id" variable in struct power_domain. At same time, we have to set of_xlate to empty to bypass standard of_xlate in uclass driver.

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.
