*	rk_pwm: remove grf setting code from driver	Kever Yang	2016-09-22	-11/+0
\| \| \| \| \| \| \| \| \|	We consider the grf setting for pwm controller select as the system operation instead of driver operation, move it to soc init, let's remove it from pwm driver first. Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org>
*	rk_pwm: use clock framework API to get module clock	Kever Yang	2016-09-22	-3/+14
\| \| \| \| \| \| \| \| \|	This patch use clock API instead of hardcode for get pwm clock. Signed-off-by: Kever Yang <kever.yang@rock-chips.com> Acked-by: Simon Glass <sjg@chromium.org> Fix printf() to debug() nit: Signed-off-by: Simon Glass <sjg@chromium.org>
*	exynos: pwm: Add a driver for the exynos5 PWM	Simon Glass	2016-05-25	-0/+130
\| \| \| \| \| \| \| \|	This driver supports the standard PWM API. There are 5 PWMs. Four are used normally and the last is normally used as a timer. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Minkyu Kang <mk7.kang@samsung.com>
*	tegra: video: Move LCD driver to use the DM PWM driver	Simon Glass	2016-02-16	-0/+1
\| \| \| \| \| \| \| \|	Use the driver-model PWM driver in preference to the old code. Signed-off-by: Simon Glass <sjg@chromium.org> Acked-by: Anatolij Gustschin <agust@denx.de> Signed-off-by: Tom Warren <twarren@nvidia.com>
*	tegra: Convert CONFIG_PWM_TEGRA to Kconfig	Simon Glass	2016-02-16	-0/+8
\| \| \| \| \| \| \| \|	Move this option to Kconfig and clean up the header files. Adjust the only user (the LCD driver) to work with the new driver. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
*	tegra: pwm: Add a driver for the tegra PWM	Simon Glass	2016-02-16	-0/+88
\| \| \| \| \| \| \| \|	This PWM supports four channels. The driver always uses the 32KHz clock, and adjusts the duty cycle accordingly. Signed-off-by: Simon Glass <sjg@chromium.org> Signed-off-by: Tom Warren <twarren@nvidia.com>
*	pwm: rockchip: Add a PWM driver for Rockchip SoCs	Simon Glass	2016-01-21	-0/+113
\| \| \| \| \| \|	Add a simple driver which implements the standard PWM uclass interface. Signed-off-by: Simon Glass <sjg@chromium.org>
*	dm: pwm: Add a PWM uclass	Simon Glass	2016-01-21	-0/+47
\| \| \| \| \| \| \|	Add a uclass that supports Pulse Width Modulation (PWM) devices. It provides methods to enable/disable and configure the device. Signed-off-by: Simon Glass <sjg@chromium.org>
*	pwm: imx: Remove unreachable code	Axel Lin	2015-05-26	-4/+0
\| \| \| \| \| \| \| \|	The break after return is unreachable code, remove it. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Stefano Babic <sbabic@denx.de> Acked-by: Heiko Schocher <hs@denx.de>
*	pwm: imx: Prevent NULL pointer dereference	Axel Lin	2015-05-26	-0/+12
\| \| \| \| \| \| \| \| \|	pwm_id_to_reg() can return NULL, so add NULL testing to prevent NULL pointer dereference. Signed-off-by: Axel Lin <axel.lin@ingics.com> Acked-by: Stefano Babic <sbabic@denx.de> Acked-by: Heiko Schocher <hs@denx.de>
*	bugfix i.mx6 pwm: prevent overflow of period_c * duty_ns	Brecht Neyrinck	2015-05-15	-1/+1
\| \| \| \| \| \| \|	Prevent overflow by casting duty_ns to ull first. This bug came up when trying to create a 200 Hz PWM Signed-off-by: Brecht Neyrinck <bnrn@psicontrol.com> Acked-by: Heiko Schocher<hs@denx.de>
*	pwm, imx6: add support for pwm modul on imx6	Heiko Schocher	2014-07-23	-0/+161
	add basic support for the pwm modul found on imx6. Pieces of this code are based on linux code from drivers/pwm/pwm-imx.c Commit "cd3de83f1476 Linux 3.16-rc4" Signed-off-by: Heiko Schocher <hs@denx.de> Acked-by: Stefano Babic <sbabic@denx.de> Cc: Wolfgang Denk <wd@denx.de>
