* honeybuns: Board specific power button and LEDsScott Collyer2021-05-141-0/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL modifies both power button press/release polairty and power button LED control signals to be board specific instead of platform specific. Previously there were platform specific macros for BUTTON_PRESSED_LEVEL and BUTTON_RELEASED_LEVEL. But, these levels will depend on how the power button circuit is designed. This CL moves these macros to board.h. In addition, macros are added to for the GPIO signals used for green/red LED control. This allows for boards that don't support the power button LED at all. BUG=b:164157329 BRANCH=quiche TEST=Verfied power button works on both quiche and gingerbread. Previously, this was only working on quiche because gingerbread has opposite polarity for the power button signal. Also, verfied that power button/status LED turns off when dock is off.

* honeybuns: Add usbc attached gpio support for usb/mst hubsScott Collyer2021-05-023-4/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This CL adds support for new GPIO signals used by the EC to notify usb/mst hubs about type-c attach and over current protection events. The usb3 only port on quiche/baklava uses a PPC, and previously the PPC was only being used to enable/disable VBUS and did not have interrupt support. However, there can still protection events that must be handled. This CL also adds a simple usbc state machine to be able to determine attached.src state while in RO. The USB hub needs to be notified when VBUS is present (BPWRDET) otherwise it will just go into suspend state and there can be USB enumeration issues. BUG=b:185066262 BRANCH=quiche TEST=manual For OCP, I set the PPC source current limit to 1.5A and connected to a chromebook. This triggers the OCP event. For BPWRDET/UFP_PLUG_DET verified that when attached, these signals are high, when detached, are low as expected.

* honeybuns: Add C2 initialization with power button on/offScott Collyer2021-04-172-42/+3
| | | | | | | | | | | | | | | | | | | | | | | This CL refactors code required for the user facing usbc port. This port was only being initialized at init time and therefore would not function properly following a power button off/on. To avoid duplicating code, the functions used to initialize this port and control VBUS were moved to usbc_support in baseboard so they can be common and are now guarded by a GPIO macro so this can be board specific for variants which don't have a PPC to control on this port.

| | | | | | | | | | | | | | | | | | | | | | | | | This CL adds support for the power button including a new task to allow for power sequencing delays. The power button is used for two purposes. First, to turn the dock on or off, and second, to allow for a user set preference of the MF for DP 2 or 4 lane selection. If the dock is off, the dock will be turned on as soon as the short press timer expires. If the dock is already on, then a short press action is only recognized on the release so a long press will only change the MF preference.
