2014-01-27regulator: s5m8767: Use GPIO for controlling Buck9/eMMCKrzysztof Kozlowski
Add support for GPIO control (enable/disable) over Buck9. The Buck9 Converter is used as a supply for eMMC Host Controller. BUCK9EN GPIO of S5M8767 chip may be used by application processor to enable or disable the Buck9. This 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; Without the patch the regulator supplying eMMC must be defined as fixed-regulator.

Add symbols for hard-coded values of BUCK_RAMP field in DVS_RAMP register. This simplifies a little the code as register update is called only once. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: Lee Jones <lee.jones@linaro.org> Signed-off-by: Mark Brown <broonie@linaro.org>

Replace hard-coded value for mask used in BUCKX_CTRL registers (for BUCKX_EN field) with a symbol. This also removes two local variables.
