Subject: [PATCH v2 0/3] pwm: add pwm AO on meson gx

The pwms found in the AO domain of the meson gx family have different
clock sources than the ones found in the EE domain. The AO pwms only
have 2 connected clock input which are clk81 and the crytal.

This patchset adds the necessary compatible and the clock data for it.

Changes since v1: [0]
* Correct clock source order for gxbb pwm ao. Documenation shows xtal as
  source #1 while it is actually source #0
* Add patch 3 to fix pwm calculation. Issue while testing pwm with clk81
  as clock source.
