Merge tag 'pwm/for-4.21-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/thierry.reding/linux-pwm

Pull pwm updates from Thierry Reding:
 "Not a lot going on this cycle.

  There's some more cleanup going on and new driver support that was not
  quite ready in time for v4.21-rc1, but here are a few fixes and
  improvements that are good to go.

  The Kona PWM driver can now be built on the Cygnus architecture and
  the i.MX driver gained support for hardware readback. Some small fixes
  are provided for the clks711x and lpc18xx-sct drivers.

  Finally, to round things off some drivers are switched to SPDX license
  identifiers"
