upnix: I would be indeed curious to see a stock firmware boot log, because I don't see a PMIC on the board. There is some unpopulated footprint near the microSD slot, though ...
<apritzel>
upnix: I take this back, there is an AXP, next to the USB slots, it's just tiny ;-)

junari_: did you post some binary vendor boot0 for your board somewhere already? Just that first few KB from an SD card at 8K (or 128k). These contain the DRAM parameters (TPRx, bit delay values), to put into jernej's new DRAM code.

Any tricks for definitively identifying the WiFi and Ethernet chips in my T95?
<jernej>
upnix: open up the box and check markings?
<upnix>
jernej: Yeah.. I guess I'll try a bit harder. I did look it over
<jernej>
you can post picture here and I can check
<jernej>
but I forgot how this can be done. something in sysfs
<apritzel>
I looked up that number on that Wifi chip yesterday, and only found sad things
<apritzel>
apparently it has been used before in some Rockchip box
<upnix>
Ok, I just wanted to make sure I wasn't missing anything easy
<apritzel>
it should be rather straightforward to make a driver for the AXP: it's only a few rails, so probably just a subset of some other X-Powers PMIC
<jernej>
it really uses internal ethernet phy (AC200)
<jernej>
but there is nothing about wifi in your log. it contains actually two boots due to system update and about half of it is just repetition
<apritzel>
jernej: I guess most of those TV boxes do now, since PHYs were (are?) heavily affected by the chip shortage
<apritzel>
jernej: and also 100 MBit/s should be enough even for a 4K stream
<jernej>
so maybe first indication would be to execute lsmod on android and they try to find SDIO ID in sysfs
<jernej>
apritzel: yeah, that's most likely explanation

But this could be different than the chip the BCM4334 is sitting in, no?
<jernej>
why it would be different?
<jernej>
you have wifi+bt module based on BCM4334 and it should be already covered by kernel
<apritzel>
yeah, sounds like good news
<jernej>
I have T95 variant with XR819
JohnDoe_71Rus has quit []
<upnix>
jernej: I thought with comapnies like Boardcom chip manufacturers would license some specification, then incorporate it into a packaged chip ... or something like that. Like how I have some D-Link XYZ wi-fi card that's really a RealTek
<upnix>
When I read about the XR819 and AW859A I assumed that was the situation
<upnix>
But anyway, I'm glad that's good news
<jernej>
I see what you mean now
<jernej>
I don't really know if it is licensed IP core or genuine BRCM chip
<jernej>
fun fact, Broadcom sold wifi section to Cypress
<upnix>
I recently realized that Marvell did something similar
<jernej>
but anyway, doesn't really matter who's the real designer of the chip. As long as it gives that ID, it should be driver compatible with BCM4334
<jernej>
well, I also made patches for cw1200 to support XR819 (AW licensed IP core from ST, it seems)
<jernej>
but they are not mainline, because they break suspend
<jernej>
I've never come around to fix this
<jernej>
but it's very old product. It shouldn't be used on new designs, but it's cheap, so yeah...
<apritzel>
The XR819 you mean? I think they still put it even in H616 TV boxes, when they are advertised as "2.4 GHz only, no BT"
<apritzel>
and you get the AW859 if it's "2.4/5GHz, with BT" :-(
<jernej>
XR829 is another possibility with BT

I just put all the regulator bits into axp20x-regulator.c, only to realise that that AXP1530 patch on the list is using the same settings
