Do you have any documentation pointing to 100 ms really being needed
here? I know that leaving this number off is rarely a good idea, but
arbitrarily picking 100 isn't great either. It could either be much
too big or much too small.

This is not a pinctrl update so it doesn't belong in the "PINCTRL"
section. Please move this above right before the "pwmleds" node.

Having a comment like "Set the PWM period to 200 microseconds (5kHz
duty cycle") wouldn't hurt either.

There is still one extra entry in "gpio-line-names". Said another way,
the max GPIO number on sc7280 is GPIO 174. As you can see above, GPIO
170 is unnamed (it has a blank string). GPIO 171 has the name
"MOS_BLE_UART_TX", GPIO 172 has "MOS_BLE_UART_RX", and then you have
blank names for GPIO 173, 174, and 175. ...but there is no GPIO 175.

So, simply put, please remove one of the lines after the line with
"MOS_BLE_UART_RX"
