Hi Jonas,

Pinconfig nodes normally bind recursively with PINCTRL_FULL and

any node marked with e.g. bootph-all will not bind unless its parent is
also marked for pre-reloc.
group1 {
pinconf1 {
bootph-all;
};
};
This cause the following warning message to be shown during U-Boot
proper pre-reloc stage on Rockchip devices, e.g on RK3568:
ns16550_serial serial@fe660000: pinctrl_select_state_full:
uclass_get_device_by_phandle_id: err=-19
and on RK3328:
ns16550_serial serial@ff130000: pinctrl_select_state_full:
uclass_get_device_by_phandle_id: err=-19
Check pinconfig nodes pre-reloc status recursively to fix this and to
make pinconfig_post_bind work same at both U-Boot proper pre-reloc and
at TPL/SPL stage.

v2:
- No change
A recent change to fdtgrep was believed to solve this however, fdtgrep
is only applied to control fdt for xPL so this issue still exist at
U-Boot proper pre-reloc stage.

You could move the ofnode child declaration here for limiting the scope.
I also got confused by "parent" name, as it isn't actually the parent
we're looking at right now, but the node itself, so it was a bit
misleading. I would have kept "node" and the "child" one is explicit enough.
In any case,
