[PATCH v2 0/9] usb/dwc3 / phy/tusb1210: Add TUSB1211 charger detection

[Hans de Goede]

Hi All,

Here is v2 of the patchs-series to add support for USB charger-type
(SDP/DCP) detection using a tusb1210 phy connected to a dwc3 controller.

Changes in v2:
[PATCH v2 9/9] phy: ti: tusb1210: Add charger detection:
- Add an online attribute to the registered power_supply class device,
  otherwise upower thinks it is an extra system battery
- Add tusb1210_remove_charger_detect() function to properly unregister
  the tusb->psy_nb notifier and to cancel tusb->chg_det_work

v1 cover-letter:

Some Android x86 tablets with a Bay Trail (BYT) SoC (with DWC3 UDC)
and a Crystal Cove PMIC, which does not support charger-detection,
rely on a TUSB1211 phy for charger-detection.

This series adds support for this, it starts with some dwc3 bug-fixes
for issues hit while developing this, as well as adding support to
the dwc3 code to set a special property checked by the tusb1210 driver
to signal that it needs to enable charger-detection.

The 2nd half of the series does some refactoring / fixes to the
tusb1210 driver and adds the charger-detection support.

Regards,

Hans
