pinctrl is the documented node name, not pin-controller.

What's wrong with just "usart1"?

I think I would like to see "-pins" appended to the node names.

You have a mixture of the number suffix being a pin mode # and block
instance #. pwm1 or pwm1-pins?

Our way of naming our node is <IP_name><instance>-<differentiator>

differentiator starts at 0, and is incremented if needed.
For example, if we want to add a sleep config, the node's name would be:

usart1_pins_sleep_a: usart1-1 { blablabla ...}

Right, if we follow our rules, the node's name must be :

pwm1_pins: pwm1-0 { ....
