2014-07-04regulator: arizona-ldo1: remove bypass functionalityNikesh Oswal
WM5110/8280 devices do not support bypass mode for LDO1 so remove the bypass callbacks registered with regulator core. Signed-off-by: Nikesh Oswal <nikesh@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org> Cc: stable@vger.kernel.org
2014-05-27regulator: arizona-ldo1: add missing #includeArnd Bergmann
commit 2cce4be9e6b8 "regulator: arizona-ldo1: Add processing of init_data from device tree" added a call to of_get_child_by_name() but did not add an #include to the header file declaring that function. I got a build error when doing randconfig testing on this, which is fixed by this patch to include of.h. drivers/regulator/arizona-ldo1.c:192:2: error: implicit declaration of function 'of_get_child_by_name' [-Werror=implicit-function-declaration] drivers/regulator/arizona-ldo1.c:193:2: error: implicit declaration of function 'of_parse_phandle' [-Werror=implicit-function-declaration] drivers/regulator/arizona-ldo1.c:213:2: error: implicit declaration of function 'of_node_put' [-Werror=implicit-function-declaration] Signed-off-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Charles Keepax <ckeepax@opensource.wolfsonmicro.com> Signed-off-by: Mark Brown <broonie@linaro.org>

2014-04-18regulator: arizona-ldo1: Move setup processing from arizona-coreCharles Keepax
It is more idiomatic to process things relating to the regulator in its driver. This patch moves both processing of device tree relating to the regulator and checking if the regulator is external from arizona-core into the regulator driver.

2014-03-18regulator: arizona-ldo1: Correct default regulator init_dataCharles Keepax
Both 5102 and 8997 have the regulator capable of supplying 1.8V, and the voltage step from the 5110 regulator is different from what is specified in the default description. This patch updates the default regulator description to match 5110 and selects the 1.8V capable description for 8997.
