[PATCH v14 00/38] phy: rockchip: usbdp: Clean up the mess

[Igor Paunovic]

Hi Sebastian,

I have now, and I owe you a correction: the 30 s was my measurement
artifact, not negotiation time.

The journal does not record the replug instant, so the figure I quoted
was deregistration to re-registration - including however long the
cable simply sat unplugged. Today, with the TCPM debugfs log and a
controlled replug:

  [12954.114919] CC1: 0 -> 2, CC2: 0 -> 1   <- replug
  [12955.837527] PD RX, header: 0x2e8f      <- PD exchange running

DRM reports the connector connected 2.1 s after the replug and the
compositor lights the output about 4 s after. The adapter negotiates
at normal speed; nothing to chase. Sorry for the noise, and thanks
for the tcpm devres fix.

Regards,
Igor
