Tegra234 has eight single-channel PWM controllers, one of them in the
AON block.

Enable in device tree and use it to drive the PWM controllers on
40 pin header of Orin dev-kit.

This does not match bindings. Either DTS or bindings need to be fixed.
Best regards,

Thanks for reviewing the patches.
Tegra234 uses same compatible as Tegra194.
And also we can clear "nvidia,tegra186-pwm" from the Tegra234 pwm compatible list.
I will update binding doc and push new patch.
Thanks & Regards,
Sandipan
