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.
