Message

Hi,

This is the PWM driver for Toshiba's ARM SoC, Visconti[0].
This has not yet been included in Linux kernel, but patches have been posted [1]
and some patches have been applied [2].

Since this is a SoC driver, this cannot work by itself, but I have confirmed that it
works with the patch series sent as [1] with DT setting.

Best regards,
  Nobuhiro
