*	mfd: Drop owner assignment from i2c_drivers	Krzysztof Kozlowski	2015-08-11	1	-1/+0
\| \| \| \| \| \| \| \|	i2c_driver does not need to set an owner because i2c_register_driver() will set it. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
*	mfd: lp3943: Make mfd_cell array const	Krzysztof Kozlowski	2014-06-03	1	-1/+1
\| \| \| \| \| \| \| \|	mfd_add_devices() expects array of struct mfd_cell to be const. Signed-off-by: Krzysztof Kozlowski <k.kozlowski@samsung.com> Acked-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
*	mfd: Add LP3943 MFD driver	Milo Kim	2014-01-21	1	-0/+167
	LP3943 has 16 output pins which can be used as GPIO expander and PWM generator. * Regmap I2C interface for R/W LP3943 registers * Atomic operations for output pin assignment The driver should check whether requested pin is available or not. If the pin is already used, pin request returns as a failure. A driver data, 'pin_used' is checked when gpio_request() and pwm_request() are called. If the pin is available, then pin_used is set. And it is cleared when gpio_free() and pwm_free(). * Device tree support Compatible strings for GPIO and PWM driver. LP3943 platform data is PWM related, so parsing the device tree is implemented in the PWM driver. Signed-off-by: Milo Kim <milo.kim@ti.com> Signed-off-by: Lee Jones <lee.jones@linaro.org>
