mfd: bd70528: Support ROHM bd70528 PMIC core
ROHM BD70528MWV is an ultra-low quiescent current general purpose single-chip power management IC for battery-powered portable devices. Add MFD core which enables chip access for following subdevices: - regulators/LED drivers - battery-charger - gpios - 32.768kHz clk - RTC - watchdog Signed-off-by: Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
