mfd: Add TPS6586x driver
Add mfd core driver for TPS6586x PMICs family. The driver provides I/O access for the sub-device drivers and performs regstration of the sub-devices based on the platform requirements. In addition it implements GPIOlib interface for the chip GPIOs. TODO: - add interrupt support - add platform data for PWM, backlight leds and charger Signed-off-by: Mike Rapoport <mike@compulab.co.il> Signed-off-by: Mike Rapoport <mike.rapoport@gmail.com> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>
