rtc: s5m: use shorter time of register update

2014-06-10T22:34:47Z

Set the time needed for updating alarm and time registers to 0.45 ms. The default is 7.32 ms which is too long and leads to warnings when setting alarm or time: s5m-rtc: waiting for UDR update, reached max number of retries Signed-off-by: Krzysztof Kozlowski Cc: Kyungmin Park Cc: Lee Jones Cc: Alessandro Zummo Cc: Sangbeom Kim Cc: Samuel Ortiz Cc: Marek Szyprowski Cc: Bartlomiej Zolnierkiewicz Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds

mfd/rtc: sec/s5m: rename SEC* symbols to S5M

2014-06-10T22:34:46Z

Prepare for adding support for S2MPS14 RTC device to the rtc-s5m driver: 1. Rename SEC* symbols to S5M. 2. Add S5M prefix to some of defines which are different between S5M876X and S2MPS14. This is only a rename-like patch, new code is not added.

mfd: sec-core: Remove duplicated device type from sec_pmic_dev

2014-06-03T07:11:21Z

The device type was stored in sec_pmic_dev state container twice: - unsigned long type (initialized from of_device_id or i2c_device_id) - int device_type (initialized as above or from board files when there is no DTS) The 'type' field was never used outside of probe so it can be safely removed. Change also the device_type in sec_pmic_dev and sec_platform_data to unsigned long to avoid any casts. Signed-off-by: Krzysztof Kozlowski Signed-off-by: Lee Jones

mfd/rtc: s5m: Do not allocate RTC I2C dummy and regmap for unsupported chipsets

2014-06-03T07:11:16Z

The rtc-s5m driver does not support all of S2M and S5M chipsets supported by main MFD sec-core driver. For such chipsets unsupported by rtc-s5m, the MFD sec-core driver initialized regmap with default config. This config in such cases wouldn't work at all. The main MFD sec-core driver shouldn't initialize regmap for child drivers which is not used by them and even not valid. Move the allocation of RTC I2C dummy device and initialization of RTC regmap from main MFD sec-core driver to the rtc-s5m driver. The rtc-s5m driver will use proper regmap config for supported devices. Signed-off-by: Krzysztof Kozlowski Acked-by: Alessandro Zummo Signed-off-by: Lee Jones

regulator: s2mps11: Add external GPIO control for S2MPS14

2014-04-14T21:12:42Z

Add support for external control over GPIO for LDO10, LDO11 and LDO12 S2MPS14 regulators. External control can be turned on by writing 0x0 to control register which in case of other regulators is used for disabling them. These LDO10-LDO12 regulators can be disabled only by I2C GPIO or PWREN pin so the patch actually allows proper way of disabling them. Additionally the GPIO control has two benefits: - It is faster than toggling it over I2C bus. - It allows disabling the regulator during suspend to RAM; The AP will enable it during resume.
