The power supply circuit in ROC-RK3399-PC is
Power Supply (or PPS) => FUSB => MP8859
VUBS pin of FUSB and IN pin of MP8859 is supplied via TYPEC_IN.
The MP8859 operated with 2.8V to 22V supply voltage and typical
applications this supply can be 12V.
This patch is trying to support the PD by changing the FUSB VBUS supply
to 12V and tune the I2C7 timings from downstream kernel.
Tested with PD3.0 PPS with supply voltages of 12V/3A and 20V/5A.
Hi Jagan,
This series works fine with a "dumb" (no PD negotiation) 5.1V Raspberry Pi PSU.
It also works fine with a Dell 45W USB-C Laptop Power Supply (model AA45NM170) which provides 5V@3A,9V@3A,15V@3A,20V@2.25A, where Linux master fails and just tells the USB-PD PSU to power-off.
I think this depends on the recent Rockchip TCPM changes. FUSB302 has
been a pain in the USB or else this platform would have launched a lot
longer ago.
Sorry, I was testing this patch on top of next-20230724 which includes https://patchwork.kernel.org/project/linux-rockchip/list/?series=757752:
8be558dcffe69b078b34b1fa93b82acaf4ce4957 ("usb: typec: tcpm: add get max power support")
1e35f074399dece73d5df11847d4a0d7a6f49434 ("usb: typec: tcpm: fix cc role at port reset")
Can you check if I am missing any other patches ?
so I guess the question is, are there any new clues and/or does this patch
make the situaton better or worse for the roc-rk3399-pc board as it stands
now.
It is working with PD3.0 (EHO 100W GaN) but seems to be inconsistent.
For the non-working cases, I did check in RK3399 and RK3588 designs
the PD run machine setup in tcpm with respect to the fusb302 chip
receiving hard reset due to BC_LVL, handler pending.
Here, is the sample log (please don't mind, the log combined with
other functions as I've enabled the static tcpm logs)

Look like Frank sent some patch related(not 100% sure) to this in
linux-usb [1], but the result is the same even with this change. I'm
still debugging tcpm, any pointers on this would be useful.
