RZ/G1 and R-Car platforms have PWM timers. This patch enables PWM support
by default.

Thanks for your patch!

If I'm not mistaken, there are no current users of this PWM block in the
current R-Car Gen2 and RZ/G1 DTS files?
If that's correct, I don't think it makes much sense to enable it already.

Simon: what do you think?

Gr{oetje,eeting}s,

Thank you for your feedback.

PWM support will be needed very soon as we are going to use pwm3 on the iwg20d platform to control the RGB display backlight.
The work to add display support is in progress, I hope it will be ready by next week, would you rather I sent this patch with the series to add display support?

Thanks,
Fab

Good to know, thanks!

That's up to Simon.  But I guess it doesn't matter much, as defconfig updates
are queued in a separate branch anyway.

You may want to send a similar patch for multi_v7_defconfig.
