2013-12-18regulator: max14577: Add regulator driver for Maxim 14577Krzysztof Kozlowski
MAX14577 chip is a multi-function device which includes MUIC, charger and voltage regulator. The driver is located in drivers/mfd. This patch adds regulator driver for MAX14577 chip. There are two regulators in this chip: 1. Safeout LDO with constant voltage output of 4.9V. It can be only enabled or disabled. 2. Current regulator for the charger. It provides current from 90mA up to 950mA. Driver supports Device Tree.

2013-12-18regulator: s5m8767: Do not use sec_reg* regmap helpersKrzysztof Kozlowski
Replace calls to sec_reg* helpers with direct usage of regmap API. The sec_reg* helpers are error-prone as they mix u8 with unsigned int and order of some of parameters (val and mask in sec_reg_update()). Also the helpers do not give any way of useful abstraction as they just call corresponding regmap function. This patch replaces: - sec_reg_read() with regmap_read(), - sec_reg_write() with regmap_write(), - sec_reg_update() with regmap_update_bits().

2013-12-12mfd/rtc: s5m: fix register updating by adding regmap for RTCKrzysztof Kozlowski
Rename old regmap field of "struct sec_pmic_dev" to "regmap_pmic" and add new regmap for RTC. On S5M8767A registers were not properly updated and read due to usage of the same regmap as the PMIC. This could be observed in various hangs, e.g. in infinite loop during waiting for UDR field change. On this chip family the RTC has different I2C address than PMIC so additional regmap is needed.
