openwrt realtek: add support for HPE 1920-48G (JG927A) and 1920-48G-PoE (JG928A)

Hardware information:

SoC: RTL8393M
Copper phy: 6×RTL8218B
Fibre phy: RTL8214FC
Flash: 32MiB SPI NOR, MX25L25635FMI
RAM: 128MiB DDR3, Micron MT41K64M16TW-107
Serial port: ±5V serial port to RJ45, ZT3232 (MAX3232 compatible)
+370W POE on JG928A model

Installation:

Initial installation follows same process as HPE 1920-24G (JG924A)
Based on prior work of Jan Hoffmann [email protected]
Additional work by Andreas Böhler [email protected]

I would add a note to the commit message that the SFP ports do not work due to missing support for the RTL8214FC on the RTL8393M target.

RTL8214FC on the RTL8393M target.

Added a note to address that.

I have tested it on my JG927A and can confirm it works on current main branch (except for the SFP ports as expected).

Thank you for opening the pull request!

Updating to set Andreas in the commit sign-off.

Jun 21 '24 12:06 howels

@svanheule please can you review this addition for the HPE 48 port 1920 switch.

Jun 24 '24 22:06 howels

Updated to set POE UCI values on ports 1-48 and add realtek PoE package for PoE model.

Jun 25 '24 21:06 howels

Updated i2c 2 and 3, as well as adding my own details to the commit and updating the sign-off.

Jul 01 '24 12:07 howels

The commit message has: GPIO: 3×RTL8231, 3×SN74LVC08A

But I don't see these anywhere in the devicetree. Am I missing something?

Also, if you're making changes to someone else's patches, you need to add your own Signed-off-by preceded by a list/description of the changes you made.

Updated as per your comments, the hardware info is actually taken from your excellent switch hardware website but if the GPIO is not relevant then I will omit that portion.

Is anyone else able to review this please? Would help complete the HPE 1920 family of switches. Thanks for your time.

I've built and run-tested a JG927A. WORKSFORME.

Retracted, pending solving some of the status LED nonsense below. I have hardware on order to test.

Updated to reflect the new Realtek target structure following move towards 6.6 kernel.

Sep 15 '24 16:09 howels

I see the kernel config changes disappeared with the rebase. Is that intentional?

I see the kernel config changes disappeared with the rebase. Is that intentional?

I checked the default config and thought they were included. Looks like I might have made a mistake, config changes are now added for both 6.6 and 5.15.
