2017-12-01power: supply: cpcap-battery: Fix platform_get_irq_byname's error checkingArvind Yadav
The platform_get_irq_byname() function returns -1 if an error occurs. zero or positive number on success. platform_get_irq_byname() error checking for zero is not correct. Signed-off-by: Arvind Yadav <arvind.yadav.cs@gmail.com> Signed-off-by: Sebastian Reichel <sebastian.reichel@collabora.co.uk>
2017-06-08power: supply: cpcap-battery: Add a battery driverTony Lindgren
On the CPCAP PMIC we can use the ADCs for monitoring the battery, and there is also a coulomb counter. So let's add basic support for the battery driver. I did not add any capacity prediction as that should probably be done in the user space. Or at least user space should tell the kernel some battery statistics and then the kernel driver could display the capacity based on that.
