Merge tag 'pwm/for-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux

Pull pwm updates from Uwe Kleine-König:
 "Just two minor fixes, a device tree binding addition to support a few
  more SoCs (without the need for driver adaptions), a driver include
  cleanup and the addition of the #linux-pwm irc channel to MAINTAINERS"

* tag 'pwm/for-7.1-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ukleinek/linux:
  pwm: th1520: fix `CLIPPY=1` warning
  pwm: jz4740: Drop unused include
  MAINTAINERS: Add #linux-pwm irc channel to pwm entry
  dt-bindings: pwm: amlogic: Document A4 A5 and T7 PWM
  pwm: imx-tpm: Count the number of enabled channels in probe
