* charge_ramp: Move ramp allowed / ilim callbacks to common codeShawn Nematbakhsh2017-10-061-0/+18
| | | | | | | | | | | | | | | | | | | | | The decision on whether to ramp (and how high) depends on the quirks of charger identification, so move the decision out of board, into the drivers that implement usb_charger. Also, rename CONFIG_CHARGE_RAMP to CONFIG_CHARGE_RAMP_SW, to better contrast with the existing CONFIG_CHARGE_RAMP_HW. BUG=None TEST=Manual on kevin, verify ramp occurs when port plugged into Z840 workstation.

* bd99955: Improve interrupt / USB charger task wake schemeShawn Nematbakhsh2016-06-161-7/+1
| | | | | | | | | | | | | | | | | | | | | | | | | Previously our charger ISR called a deferred task which woke our charger task. We can skip the deferred task and just wake our charger task directly. The other meaningful change here is to assume that we're using the charger for VBUS detection / BC1.2 if we have a usb_chg task, which holds true for all of our current boards with this charger. BUG=None TEST=Manual on kevin with subsequent commit. Verify charger connect / disconnect detection works properly on both ports, with zinger, donette and generic DCP charger.

* BD99955: Use only one USB charger task for both the portsVijay Hiremath2016-06-141-0/+7
| | | | | | | | | | | | | | | | | | | | | There is only one charger IC and one interrupt PIN for both the ports and also from the ISR it's not possible to decode from which port the interrupt is triggered hence a deferred function is used to trigger the wake event for the ports. As there is no additional benefit of having an extra task, added code to use only one USB charger task for both the ports. BUG=chrome-os-partner:54272 BRANCH=none TEST=Manually tested on Amenia. BC1.2 detection is success and the battery can charge on both the ports (VBUS/VCC).

* Driver: BD99955: Use Charger interrupt to detect VBUS activityVijay Hiremath2016-06-081-0/+13
| | | | | | | | | | | | | | | | | | | Added support to enable the BD99955 charger interrupt to detect the VBUS activity. With this approach GPIO USB_Cx_VBUS_DET_N pin can be removed. BUG=chrome-os-partner:53688 BRANCH=none TEST=Manually tested on Amenia. Type-C, DCP & SDP chargers can negotiate to desired current & voltage. Battery can charge.
