Frank Li 6df320abbb dt-bindings: pwm: imx: Add i.MX93, i.MX94 and i.MX95 support
Add compatible string "fsl,imx93-pwm", "fsl,imx94-pwm" and "fsl,imx95-pwm",
which is backward compatible with i.MX7ULP. Set it to fall back to
"fsl,imx7ulp-pwm".

description: |
The TPM counter and period counter are shared between multiple
channels, so all channels should use same period setting.
