Subject: [PATCH v2 0/8] EC-based USB Power Delivery support for Chrome machines

Hi,

this series contains a driver that exposes a power_supply to userspace
representing a port that support USB PD charging.

Allows userspace to display to the user if the machine is charging and
on which port, and if another device is being charged by a port. Also
allows to limit the current draw for thermal reasons.

Thanks,

Tomeu

Changes in v2:
- Allocate enough for the structs in cros_ec_get_host_command_version_mask,
  not their pointers.
- Allocate msg in the stack in get_next_event and
  get_keyboard_state_event, as suggested by Gwendal.
- Remove the mention to Type C from the comments where it didn't make
  sense, as suggested by Benson Leung.
- Split out changes to cros_ec_commands.h and the helpers added to
  mfd/cros_ec.h from the patch that adds the charger driver, as
  suggested by Lee.
- Actually call get_ec_num_ports.
- Move cros_ec_usb_pd_charger_register into cros_ec_dev.c
