This patch series enables the ePWM support on the AM62 platform.
The ePWMs are enabled by default, but we have to disable them
for the AM625-SK board, as they are not in use.

Add the compatible DT nodes for all EPWM instances
present in AM62 SoC. There is a total of 3 EPWM modules
available, sharing the same K3 IP as in AM64 SoC.

This also adds a required "ti,am62-epwm-tbclk" clock
provider node for the EPWM time-base clock.

Add epwm nodes and mark them disabled, as they're
not currently in use.

Lets do this in the next rc1 cycle. we should have all the missing
pieces in master by then.

I have applied the following to branch master on [1].
Thank you!

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent up the chain during
the next merge window (or sooner if it is a relevant bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.
