[0/4] i.MX8M PWM polarity support

Message

Hello,

this patchset adds the possibility to specify a PWM polarity inversion for
i.MX8M. The pwm-imx27 driver already supports this in the 3rd pwm-cells, but
the DT for imx8m so far only set #pwm-cells=<2>.
Add support by setting #pwm-cells=<3> and adding the (default) normal (0)
polarity to all boards.
make dtbs_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/pwm/imx-pwm.yaml
was used to get all boards.

Best regards,
Alexander
