* pwm: sun4i: Drop legacy callbacksAlexandre Belloni2017-07-061-160/+0
| | | | | | | | | | Remove the legacy callbacks .enable(), .disable(), .set_polarity() and .config().

* pwm: sun4i: Switch to atomic PWMAlexandre Belloni2017-07-061-0/+166
| | | | | | | | | | Switch the driver to atomic PWM. This makes it easier to wait a proper amount of time when changing the duty cycle before disabling the channel (main use case is switching the duty cycle to 0 before disabling).

* pwm: sun4i: Improve hardware read outAlexandre Belloni2017-07-061-19/+46
| | | | | | | | | | Implement .get_state instead of only reading the polarity at probe time. This allows to get the proper state, period and duty cycle.

* pwm: Remove .can_sleep from struct pwm_chipThierry Reding2017-01-041-1/+0
| | | | | | | All PWM devices have been marked as "might sleep" since v4.5, there is no longer a need to differentiate on a per-chip basis. Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
* pwm: sunxi: Add H3 supportMilo Kim2016-09-081-0/+9
| | | | | | | | | | | | | | | | | | | | H3 PWM controller has same register layout as sun4i driver, so it works by adding H3 specific data.

* pwm: Use pwm_get/set_xxx() helpers where appropriateBoris Brezillon2016-05-171-1/+2
| | | | | | | | | 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.

* pwm: sunxi: Fix whitespace issueOlliver Schinagl2015-11-101-1/+1
| | | | | | | | This patch changes no code, it just fixes the whitespacing. Operators should be separated from operands by a single space. Signed-off-by: Olliver Schinagl <oliver@schinagl.nl> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
* pwm: sun4i: Add support for PWM controller on sun5i SoCsHans de Goede2015-11-101-2/+23
| | | | | | | | | | The PWM controller on sun5i SoCs is identical to the one found on sun7i SoCs. On the A13 package only one of the 2 pins is routed to the outside, so only advertise one PWM channel there.

This adds a generic PWM framework driver for the PWM controller found on Allwinner SoCs. Signed-off-by: Alexandre Belloni <alexandre.belloni@free-electrons.com> Acked-by: Maxime Ripard <maxime.ripard@free-electrons.com> Signed-off-by: Thierry Reding <thierry.reding@gmail.com>
