Please keep the RK_Pxx macros.

I’m not sure if pci-clkreqn is functional at all. If not I’m not sure if we should add it to the dtsi.
Shawn may know more about it.

Could we actually use RK_Pxx for all new pin definitions? Would increase readability a lot.

Yep, wasn't there a big change away from clkreqn, due it
not being functional?

Especially as the above change really only seems to change RK_PD0 back
to 24, so this block (and some others) will go away entirely.

Please refer to commit 461a00bb9d539e
("arm64: dts: rockchip: kill pcie_clkreqn and pcie_clkreqnb for rk3399")
CLKREQ# is used for PCI-PM L1.x, but it's not functional for rk3399, so
we have to support CPM(clock power management), thus I kill them last
year.
