This patch add cose related to regulator. To control powre consumeption have registered the voltage consumer of WM8994 to the regulator framework. Additionally, I explain the constraints of the regulator of WM8994 codec. All these consumer supply of WM8994 codec connected the regulator(VCC_1.8V) on a circuit diagram. "VCC_1.8V" regulator is always enabled, because it is used to many devices on Goni/Aquila board. This is required especially when there are many devices physically attached to "VCC_1.8V" and some of they did not "register" as consumers to "VCC_1.8V". "VCC_1.8V" might be turned off by those who are registered while "unregistered" are still active Signed-off-by : Chanwoo Choi <cw00.choi@xxxxxxxxxxx> Signed-off-by : Joonyoung Shim <jy0922.shim@xxxxxxxxxxx> Signed-off-by : Kyungmin Park <kyungmin.park@xxxxxxxxxxx> --- arch/arm/mach-s5pv210/mach-aquila.c | 119 +++++++++++++++++++++++++++++++++++ arch/arm/mach-s5pv210/mach-goni.c | 119 +++++++++++++++++++++++++++++++++++ 2 files changed, 238 insertions(+), 0 deletions(-) diff --git a/arch/arm/mach-s5pv210/mach-aquila.c b/arch/arm/mach-s5pv210/mach-aquila.c index 92dad41..825d70c 100644 --- a/arch/arm/mach-s5pv210/mach-aquila.c +++ b/arch/arm/mach-s5pv210/mach-aquila.c @@ -16,6 +16,8 @@ #include <linux/i2c.h> #include <linux/i2c-gpio.h> #include <linux/mfd/max8998.h> +#include <linux/mfd/wm8994/pdata.h> +#include <linux/regulator/fixed.h> #include <linux/gpio_keys.h> #include <linux/input.h> #include <linux/gpio.h> @@ -379,6 +381,120 @@ static struct max8998_platform_data aquila_max8998_pdata = { };
