If not inverted please drop the this flag.
Also you need to add
&pwm4 {
status = "okay";
};
And so you can do the pwm pinctrl within that node, see below.

status can be dropped too.

Missing the muxing?

Please sort the nodes alphabetical.

please add 'grp'

IMHO the muxing is part of the pwm4 node. So rename it to
'pinctrl_pwm4: pwm4grp'.
