* tcpm: Move tcpm.h into an include directorySimon Glass2020-12-221-1/+1
| | | | | | | | | | | | | | | | | | This header file is used from quite a few files, relying on the EC build system to find includes in the driver/tcpm directory. For Zephyr we don't want to add that as an include. It makes more sense for header files to be in an include directory, so move it and fix up the users.

* tree: Use new atomic_* implementationDawid Niedzwiecki2020-10-271-5/+4
| | | | | | | | | | | | | | | | | | | | | | | It is done as a part of porting to Zephyr. Since the implementation of atomic functions is done for all architectures use atomic_* instead of deprecated_atomic_*. Sometimes there was a compilation error "discards 'volatile' qualifier" due to dropping "volatile" in the argument of the functions, thus some pointers casts need to be made. It shouldn't cause any issues, because we are sure about generated asm (store operation will be performed).

* core: rename atomic_clear to atomic_clear_bitsDawid Niedzwiecki2020-10-061-1/+1
| | | | | | | | | | | | | | | | | | Change the name of atomic_clear to atomic_clear_bits to make to name more clear - the function clears only selected bits, but the name may suggest that it clears the whole variable. It is done as a part of porting to Zephyr, where atomic_clear zeros the variable.

| | | | | | | | | | | | | | | | | | | The AOZ1380 always started off with not sinking and not sourcing. In a batteryless or dead battery condition this is not true.

* Add a board specific helper to return USB PD port countKarthikeyan Ramasubramanian2019-11-091-1/+1
| | | | | | | | | | | | | | | | | | | | | Certain SKUs of certain boards have less number of USB PD ports than configured in CONFIG_USB_PD_PORT_MAX_COUNT. Hence define an overrideable board specific helper to return the number of USB PD ports. This helps to avoid initiating a PD firmware update in SKUs where there are less number of USB PD ports. Also update charge manager to ensure that absent/ invalid PD ports are skipped during port initialization and management.
