Hello Cenk,

Please see a few comments below.

from the vendor. Unfortunately the &wireless_bluetooth
and &wireless_wlan are not implemented yet.

Bigger parts of the rk3588s-orangepi-5.dts file were
moved into a new rk3588s-orangepi-5.dtsi file, so
that both device trees from the orangepi-5 and 5b
include from it and avoid including from the .dts.

This changes the Orange Pi 5's sdmmc alias to be mmc1,
breaking existing users if they used the /dev/mmc0 device
file, so it's consistent with all the other rk3588 DTS,
which, is also the new default that rockchip wants to use.

Therefore also add the sdhc alias to be mmc0 on the
rk3588s-orangepi-5b.dts.

It would be good to reflow the patch description to use the
76-or-so-column width a bit better.

How does this board differ from the original Orange Pi 5?
- the Orange Pi 5 has a M.2 NVMe M-key PCI 2.0x1
slot (hooked to combphy0_ps) whereas the Orange Pi 5b uses combphy0_ps
for the WiFi.
- The Orange Pi 5 with the M.2 socket has a regulator defined hooked to
"GPIO0_C5" (i.e. PCIE_PWREN_H) whereas the Orange Pi 5B has GPIO0_C5
hooked to BT_WAKE_HOST.
- builtin eMMC storage
- no SPI NOR flash (u-boot, preboot etc. initiates
from within the eMMC
storage)
- ap6275p Wifi module (like the Orange Pi 5 Plus)
- builtin BlueTooth module

Please see my patch [1] that presents use of a set of git-diff(1)
parameters that could also, possibly, reduce the size of this patch
significantly and increase its readability.
