power: bq27xxx_battery: Fix bq27541 AveragePower register address

2016-01-14T00:03:18Z

Currently in bq27541 driver, the average power register address is incorrectly set to 0x76, which would result in an error: bq27xxx-battery 2-0055: error reading average power register 10: -11 According to the bq27541 datasheet, fix this problem by setting the average power register address to 0x24.

power: Fix unmet dependency on POWER_SUPPLY by POWER_RESET by uncoupling them

2015-12-08T03:26:05Z

Currently the reset/power off handlers (POWER_RESET) and Adaptive Voltage Scaling class (POWER_AVS) are not built when POWER_SUPPLY is disabled. The POWER_RESET is also not visible in drivers main section of config. However they do not really depend on power supply so they can be built always. The objects for power supply drivers already depend on particular Kconfig symbols so there is no need for any changes in drivers/power/Makefile. This allows selecting POWER_RESET from main drivers config section and fixes following build warning (encountered on ARM exynos defconfig when POWER_SUPPLY is disabled manually): warning: (ARCH_HISI && ARCH_INTEGRATOR && ARCH_EXYNOS && ARCH_VEXPRESS && REALVIEW_DT) selects POWER_RESET which has unmet direct dependencies (POWER_SUPPLY) warning: (ARCH_EXYNOS) selects POWER_RESET_SYSCON which has unmet direct dependencies (POWER_SUPPLY && POWER_RESET && OF) warning: (ARCH_EXYNOS) selects POWER_RESET_SYSCON_POWEROFF which has unmet direct dependencies (POWER_SUPPLY && POWER_RESET && OF) Reported-by: Pavel Fedin Signed-off-by: Krzysztof Kozlowski Signed-off-by: Sebastian Reichel
