The v2 version of this patch was here:
https://lore.kernel.org/all/20230126124651.1362533-7-abel.vesa@linaro.org/

Changes since v2:
 * none

Changes since v1:
 * switched from qmp-usb to qmp-combo as it will support DP also
 * changed all hex offset values to lowercase, like Vinod suggested

It seems the code in qmp_combo_parse_dt() using those dp_tx0/dp_tx1 were lost
in the combo comversion process.

The code was:

But something similar is being discussed in https://lore.kernel.org/all/20230123120807.3101313-1-dmitry.baryshkov@linaro.org/
and also submitted as https://lore.kernel.org/all/20230120-sm6350-usbphy-v4-0-4d700a90ba16@fairphone.com/

I'm not a bug fan of the "txa" & "txb" namings since HW registers are named TX0/1 and RX0/1,
and the non-combo PHY uses 0 & 1...
