eh i guess rt9301 is the main blocker... @olliver from 1 to 10 how much do you think it's possible to support the switch in this configuration?
Check the @spol-eff 's posts above - he did some digging into userspace tools from OEM firmware.
saddly if the solution will be accept having a precompiled userspace bin from an OEM firmware to make the switch work... then i'm pretty negative about it...
I don't think we would need to resort to this. My understanding is we can just issue the same set of commands in our own way. Switch is already reporting itself as up as dp5_syn. Hopefully just some initialization would be needed to at least make it working as dumb switch
@Ansuel long term or short term?
Short term, 1%; I suppose if you can run the supplied blob it would be okay.
Longerm, 99% 
I'm (re)writing the I2C driver right now, with using regmap that allows for either MMIO (register based) or SPI access. I don't have any hardware, so that'll be a thing.
The biggest problem however regardless (to keep up with motiviation etc) is getting rtl93xx based merge requests merged. Having a tree with 250 patches is getting tiresome and demotiviating in continuing to work on it 
But shouldn't be a huge problem, as long as we keep moving forward.
my biggest concern is not being able to emulate what the userspace thing does
resulting in never being able to setup the switch
From where I'm sitting, I don't see an issue generally. We drive the switch chip the same way, just over SPI. The only scare is, the 'undocumented bits'. E.g. what if the blob sends some initit junk that we have no idea about, that's not obvious. That'll be needing some reverse engineering. But I'd be supprised if they made it that complex.
meanwhile this is my updated understanding of how everything is connected. Folks, let me know if something is off here:

[ 3.424590] spi_qup 78b9000.spi: deferred probe timeout, ignoring dependency
Its rather simple, because the downstream kernel doesn't have the node so I had no idea where the bus actually is, there should actually be 5 SPI buses and 5 I2C buses.
Copy/pasting decompiled nodes won't work, all of the phandle references will be broken obviously.
Can you post the whole stock DTS in order to configure the pinctrl?
ok, understood.
realized that later too by looking at the .dtsi tlmm section
Here are the links (old ones are dead 
)
- FDT decompiled: https://transfer.sh/gvdOeP/cr1000.dts
- /proc/device-tree-decompiled: https://transfer.sh/6erDuU/cr1000a.dts
there are 3 spi busses (one disabled and without pinctrls.. half defined?)
and 2 i2c busses there.
What's the best course of actions here? Are you gonna add those to .dtsi?
Yeah, I will add the bus you need to DTSI and send it upstream.
Pinctrl will obviously be set in your device DTS.
1 Like
Don't we want to add them all? Not only one?
Why?
There isnt really a point of adding untested stuff.
Can you try picking:
And then obviously you need to set the pinctrl in the board DTS as well.
To reduce the amount of investigative work for other devices? I could see the reason to probably keep it separate, like in '-experimental.dtsi' or something, but have all those pieces of info scattered across forums is just a waste imo.
Re commit: will try in few hours.
ok. thanks for patch; 2nd spi works too now

Any hints on how to fix those are appreciated
You need to add a spidev in DTS and then there are userspace tools or directly from the kernel.
get a powerstrip with a switch on it 
So one thing I'd name differently is to also put the SDS numbers there (far more important than just the port numbers). So a1 is actually unknown which SDS it uses, The shell script should be able to tell us that; or dumping the reg-config at the worst.
https://svanheule.net/switches/rtl93xx#section9301 I have listed what I know of the possible SDS, the mapping SDS -> port tells us a lot generally. My guess, its either SDS5, maybe SDS7 (which seems like a SDS we can configure as USGMII). Can you already see if the CPU port is 'port 28' on the switch? (config scripts), as that would confirm that (ish).
what you call 'port 8' thus is SDS2. port 24 is SDS4. What throws is me off though is port20. because SDS3 is a 10gbit port; that means when using an octal PHY, we'd get port 16 - 23. Since we are only using a quarter of the bandwidth, I would think port 16 thus.
As for the SPI bus, would be good to know which bus it is exactly (32765 sounds like a generated number). Bus4 sounds plausible though?
There's reasons to do and not do it. having them all defined in the DTS as 'status = disabled' has my preference; but it also requires to at least know it actually works if you have development hardware, that's easy-ish; as you can just poke the pins to see if it works.
But adding noise to the DTS, without verification is much nastier 'bu a_guy said there's an 4th SPI bus, but it's not working
https://www.kernel.org/doc/html/latest/spi/spidev.html is a good article, but while i2cdev is nicely usable, the spidev maintainer didn't want to support this, so some hacking is needed (using a known compatible for example which exposes spidev). Then compile the userspace app (which actually lives in the kernel tree) as your basic. Making it accept input (address) and dump output would be a good start to debug stuff
