cover arm64: Add basic support for QNAP TS-433

Hello,

this is an initial dts to support QNAP's TS-433 NAS. It's enough to start the debian installer with a custom built kernel (original Debian kernel fails to open a console, didn't debug that yet) and access HD, eMMC, RTC and network.

There are still some missing bits and pieces, but to make people aware there are efforts to support this machine and so prevent duplicate work, I think it makes sense to add the dts in its current form already.

Best regards
Uwe

PATCH 2/2 arm64: dts: rockchip: Add basic support for QNAP TS-433

In reply to Uwe Kleine-König

This is enough to make eMMC, networking, UART (console), RTC and a hard disk accessible. Still missing are (at least): USB, LEDs, regulators, fan.

woohoo and yes we're adding support for not 100% supported boards all the time, so adding basic support and extending it later is fully ok.

For people thinking about "following along at home", how much voodoo is involved to make the device boot said Debian installer? ;-)

My bot found new DT warnings on the .dts files added or changed in this series.

Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not.

If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date:

  pip3 install dtschema --upgrade

I'd ask these people for some patience as I intend to document the details in the Debian wiki.

For those who are not that patient, here comes the short version:
I compiled v6.8-rc1 with this patch, put the resulting kernel image (Image) and device tree into /srv/tftp, together with the initrd[1] from Debian and then typed in U-boot (using the vendor version):

	setenv laptop 192.168.144.173
	setenv bootargs ${bootargs} clk_ignore_unused ignore_loglevel
	i2c dev 0; i2c mw 0x20 0xf4 0x10; i2c mw 0x40 0x00 0xa3; run phy_cmd
	dhcp ${fdt_addr_r} ${laptop}:rk3568-qnap-ts433.dtb
	dhcp ${kernel_addr_r} ${laptop}:Image
	dhcp 0x0b100000 ${laptop}:debian/20240222-02:09/initrd.gz
	booti ${kernel_addr_r} 0x0b100000:$filesize ${fdt_addr_r}

Feel free to ping me on irc if you have further questions.

Best regards
Uwe

Yes, I saw these, too. But given that the added dts doesn't touch these two nodes, I thought this to be a problem of rk3568.dtsi that I can ignore for this series.

I think I found suitable fixes for those in [0].

The question would be, if the bot finding errors causes the patch to get removed from the review queue, because the binding addition still would profit from an Ack :-)

Have you tried phy-mode = "rgmii-id"; and not have these two _delay settings?

In general, we try to have the PHY do the delay, not the MAC, so that all devices work the same.

and this makes the machine unable to complete dhcp. I see the requests and replies on the dhcp server side, but the machine tells me not to receive a dhcp reply. So the above patch breaks the receive path.

O.K.

This binding is particularly bad. What does 0x3c mean? Generally, we use rx-internal-delay-ps making it clear what the value means.

RGMII requires a 2ns delay between the clock and the data. Generally, we have the MAC insert 0 delay, and request the PHY add the 2ns delay by specifying "rgmii-id". Sometimes you need to fine tune this, because of the length of the tracks etc. You can then do that fine tuning either in the PHY, or the MAC.

Looking at the binding:

tx_delay:

    description: Delay value for TXD timing.
    $ref: /schemas/types.yaml#/definitions/uint32
    minimum: 0
    maximum: 0x7F
    default: 0x30

rx_delay:

    description: Delay value for RXD timing.
    $ref: /schemas/types.yaml#/definitions/uint32
    minimum: 0
    maximum: 0x7F
    default: 0x10

For your board, you have increased both values from there default values. My guess is 0x30 tx_delay is 2ns, and 0x10 rx_delay is also 2ns.

So maybe try:

rx_delay = <0x1f>;
tx_delay = <0x0c>;

combined with rmgii-id.

With the right phy driver (MOTORCOMM_PHY) enabled, it works also without specifying {rx,tx}_delay. Thanks to Oleksij for the relevant hint. I'll switch to that then.
