General hardware info:
----------------------
D-Link DGS-1210-28MP rev. F1 is a switch with 24 ethernet ports and 4
combo ports, all ports Gbit capable. It is based on a RTL8382 SoC @ 500MHz,
DRAM 128MB and 32MB flash. 24 ethernet ports are 802.3af/at PoE capable
with a total PoE power budget of 370W.
Power over Ethernet:
--------------------
The PSE hardware consists of three BCM59121 PSE chips, serving 8 ports
each. They are controlled by a Nuvoton MCU.
In order to enable PoE, the realtek-poe package is required. It is
installed by default, but currently it requires the manual editing of
/etc/config/poe. Keep in mind that the port number assignment does not
match on this switch, alway 8 ports are in reversed order: 8-1, 16-9 and
24-17.
LEDs and Buttons:
-----------------
On stock firmware, the mode button is supposed to switch the LED indicators
of all port LEDs between Link Activity and PoE status. The currently
selected mode is visualized using the respective LEDs. PoE Max indicates
that the maximum PoE budget has been reached.
Since there is currently no support for this behavior, these LEDs and
the mode button can be used independently.
Serial connection:
------------------
The UART for the SoC (115200 8N1) is available via unpopulated standard
0.1" pin header marked J6. Pin1 is marked with arrow and square.
Pin 1: Vcc 3.3V
Pin 2: Tx
Pin 3: Rx
Pin 4: Gnd
OEM installation from Web Interface:
------------------------------------
1. Make sure you are booting using OEM in image 2 slot. If not, switch to
image2 using the menus
System > Firmware Information > Boot from image2
Tools > reboot
2. Upload image in vendor firmware via Tools > Backup / Upgrade
Firmware > image1
3. Toogle startup image via System > Firmware Information > Boot from
image1
4. Tools > reboot
Other installation methods not tested, but since the device shares the
board with the DGS-1210-28, the following should work:
Boot initramfs image from U-Boot:
---------------------------------
1. Press Escape key during `Hit Esc key to stop autoboot` prompt
2. Press CTRL+C keys to get into real U-Boot prompt
3. Init network with `rtk network on` command
4. Load image with `tftpboot 0x8f000000
openwrt-rtl838x-generic-d-link_dgs-1210-28mp-f-initramfs-kernel.bin`
command
5. Boot the image with `bootm` command

The D-Link DGS device tree was reorganized to better reflect the common
DT parts. The common include is named SOC specific (838X) and it seemed
like a good choice to add another common include in the future for the
RTL839X devices. From the current point of view this option is not really
needed.
1. The common part only includes data that matches RTL839X devices too.
2. The Panasonic DT structure avoids including the basic DTSI inside the
common DTSI.
Taking simplicity of the Panasonic include logic and in perparation to
provide DGS-1210-52 support it makes sense to harmonize this.
- rename common include to reflect its content
- move the link to the root DTSI directly to the device specific DTS

I have collected the known information from the dts files we have.
After that I made a new device tree that should work for this whole D-Link
switch family.
This device tree is based on modules where you first select which SoC group
the device belongs to. Then you include the GPIO dtsi file depending on what
hardware your device has, see examples below.
This tree is also expandable for more hardware,
see the part 'Future expansion possibilities' further down.
-------------------------------------------------------------------------------
The device tree now looks like this:
----------------
| rtl838x.dtsi | // Note 1.
----------------
|
|
---------------------------------------
| rtl838x_d-link_dgs-1210_common.dtsi | // Note 2.
---------------------------------------
|
| --------------
|-------| device.dts | // Note 3.
| --------------
|
-------------------------------------
| rtl83xx_d-link_dgs-1210_gpio.dtsi | // Note 4.
-------------------------------------
|
| --------------
|-------| device.dts | // Note 5.
--------------
Note 1; Included in rtl838x_d-link_dgs-1210_common.dtsi.
Note 2; SoC level information and memory mapping. Choose which one to include
in the device dts.
Note 3; At this point dgs-1210-16 will come out here.
Note 4; In this dtsi only common board hardware based on the rtl8231 is found.
No PoE based hardware in this dtsi.
In this dtsi there is no <#include> to above *_common.dtsi.
Note 5; Device dts with only rtl8231 based hardware without PoE will come out
here.
-------------------------------------------------------------------------------
How to set up in dts file:
The device dts will have one of these two <#include> alternatives.
This alternative includes only common features:
<#include "rtl838x_d-link_dgs-1210_common.dtsi">
This alternative includes common and the rtl8231 GPIO (no PoE) features:
<#include "rtl838x_d-link_dgs-1210_common.dtsi">
<#include "rtl83xx_d-link_dgs-1210_gpio.dtsi">
-------------------------------------------------------------------------------
Implementation:
Finally, I also implemented this new family device tree on the current
supported devices:
dgs-1210-10p
dgs-1210-16
dgs-1210-20
dgs-1210-28
The implementation for the dgs-1210-10p is different. I have removed the
information from the rtl8382_d-link_dgs-1210-10p.dts that is already present
in rtl838x_d-link_dgs-1210_common.dtsi.
Since the rest isn't officially probed in the device dts I do not want to
include the rtl83xx_d-link_dgs-1210_gpio.dtsi with dgs-1210-10p.dts.
Since I don't have these devices to test on I have built the original firmware
for each one of these devices before this change and saved the dtb file and
then compared the original dtb file with the dtb file built with this new
device tree.
-------------------------------------------------------------------------------
Future expansion possibilities:
In parallel with the rtl838x_d-link_dgs-1210_common.dtsi in the tree map
we can make a rtl839x_d-link_dgs-1210_common.dtsi to use the rtl839x.dtsi if
the need arises with more devices based on rtl839x soc.
When we have more PoE devices so the hardware map for these gets more clear
we can make a rtl83xx_d-link_dgs-1210_poe.dtsi below
the rtl83xx_d-link_dgs-1210_gpio.dtsi in the tree map.
I looked at the port and switch setup to see if it could be moved to the dtsi.
I decided not to touch this part now. The reason was that there isn't really
any meaningful way this could be shared between the devices.
The only thing in common over the family is the 8+2sfp ports on the
dgs-1210-10xx device.
And then there is the hot plug SFP and I2C ports that aren’t implemented
on any device. So maybe when we see the whole port map for the family
then maybe the ports can be moved to a *_common.dtsi but I don't think it is
the right moment for that now.

A GPIO assert is required to reset the system. Otherwise, the system

This patch adds "dts-5.10" directory to use backported drivers.
There are several specification changes in the new drivers, so there
are some compatibility issues in using dts/dtsi files for 5.4.
The old DTS files are moved to "dts-5.4", so their corresponding
kernel version is obvious as well.
