| | | | | | | | | | | | | | | | | | | In some of NVIDIA Tegra's platform, PWM controller is used to control the PWM controlled regulators. PWM signal is connected to the VID pin of the regulator where duty cycle of PWM signal decide the voltage level of the regulator output. When system enters suspend, some PWM client/slave regulator devices require the PWM output to be tristated. Add DT binding details to provide the pin configuration state from PWM and pinctrl DT node in suspend and active state of the system.

The number of supported PWMs varies on a per-board basis, but we can autodetect this by checking the error codes, so we don't need an extra property for this. And because the EC only allows specifying the duty cycle and not the period, we don't specify the period via pwm-cells, and instead have only support for one cell -- to specify the index.

This driver has been unusable with multiarch because of the hardware timer access. With the recent PWM changes, we can finally fix the driver for multiarch and device tree support. And naturally there is no rush for these for the -rc cycle, these can wait for the merge window. The PWM changes have been acked by Thierry. For the media changes I did not get an ack from Mauro but he was Cc'd in the discussion and these changes do not conflict with other media changes. After this series we can drop the remaining omap3 legacy booting board files finally. * tag 'omap-for-v4.8/ir-rx51-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap: ir-rx51: use hrtimer instead of dmtimer ir-rx51: add DT support to driver ir-rx51: use PWM framework instead of OMAP dmtimer pwm: omap-dmtimer: Allow for setting dmtimer clock source ir-rx51: Fix build after multiarch changes broke it

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP GP timers can have different input clocks that allow different PWM frequencies. However, there is no other way of setting the clock source but through clocks or clock-names properties of the timer itself. This limits PWM functionality to only the frequencies allowed by the particular clock source. Allowing setting the clock source by PWM rather than by timer allows different PWMs to have different ranges by not hard-wiring the clock source to the timer.
