	Use pwm_get/set_xxx() helpers instead of directly accessing the pwm->xxx field. Doing that will ease adaptation of the PWM framework to support atomic update. Signed-off-by: Boris Brezillon <boris.brezillon@free-electrons.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2016-03-23	pwm: lpc18xx-sct: Test clock rate to avoid division by 0	Wolfram Sang
	The clk API may return 0 on clk_get_rate(), so we should check the result before using it as a divisor. Signed-off-by: Wolfram Sang <wsa+renesas@sang-engineering.com> Acked-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
2015-09-09	pwm: NXP LPC18xx PWM/SCT driver	Ariel D'Alessandro
	This commit adds support for NXP LPC18xx PWM/SCT. NXP LPC SoCs family, which includes LPC18xx/LPC43xx, provides a State Configurable Timer (SCT) which can be configured as a Pulse Width Modulator. Other SoCs in that family may share the same hardware. The PWM supports a total of 16 channels, but only 15 can be simultaneously requested. There's only one period, global to all the channels, thus PWM driver will refuse setting different values to it, unless there's only one channel requested.
