* sunxi: power: axp809.c: Fix aldo1-2 being disabled for mvolt != 0Rask Ingemann Lambertsen2017-03-09-1/+1
| | | | | | | | | | | | | | | | | | | | | 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.
