Next, with DP 4 lane (not working on mainline but still plugged into a
screen) the diff is quite a bit bigger.

Not attaching the diff because it's quite a lot
$ diff --ignore-case -U0 usb_1_qmpphy_20240503_151052_android_4lane.txt usb_1_qmpphy_20240503_122443_mainline_4lane.txt
Not sure this is helpful to anyone, but at least wanted to share what
I've done so far here.
Thanks a lot for the traces, it founds out the QPHY_V3_DP_COM_PHY_MODE_CTRL stays at 0x3,
which means the mode doesn't get broadcasted to the phy because.... the retimer only broadcasts
the orientation and not the mode... and it works on the HDKs and the X13s because they don't have retimers.
Hi Neil,
This was it!
So I made the changes in nb7vpq904m and ptn36502 drivers to get the next mux and broadcast the typec mode,
if you find time could you test it ?
Bjorn could you also test on the rb3gen2 ?
The changes:

With this ptn36502 patch on top, I can confirm that DP 4-lane seems to
work on qcm6490-fairphone-fp5 smartphone with DP over USB-C!
Tested with a USB-C dongle that only has a HDMI port on the other side
(so no USB), and cat'ing dp_debug while connected showed num_lanes = 4
So feel free to add my:

Thanks a lot for testing, spinning a v2 with those patches!
