2017-05-01power: supply: isp1704: Fix unchecked return value of devm_kzallocPan Bian1-0/+4
Function devm_kzalloc() will return a NULL pointer. However, in function isp1704_charger_probe(), the return value of devm_kzalloc() is directly used without validation. This may result in a bad memory access bug.

2017-05-01power: supply: sbs-battery: fix the sbs interrupt requestRyosuke Saito1-1/+1
Since we use the default primary handler for the irq, IRQF_ONESHOT must be set. Otherwise the request fails and the following errors are displayed: genirq: Threaded irq requested with handler=NULL and !ONESHOT for irq 129 sbs-battery 0-000b: Failed to request irq: -22 Signed-off-by: Ryosuke Saito <raitosyo@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2017-05-01power: supply: add battery driver for AXP20X and AXP22X PMICsQuentin Schulz3-0/+515
The X-Powers AXP20X and AXP22X PMICs can have a battery as power supply. This patch adds the battery power supply driver to get various data from the PMIC, such as the battery status (charging, discharging, full, dead), current max limit, current current, battery capacity (in percentage), voltage max and min limits, current voltage and battery capacity (in Ah). This battery driver uses the AXP20X/AXP22X ADC driver as PMIC data provider.
