[PATCH v3 0/6] EC-based USB Power Delivery support for Chrome machines

[Tomeu Vizoso]

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.

Thanks,

Tomeu

Changes in v3:
- Remove duplicated prototype of cros_ec_get_host_event.
- Use do_div so it builds on 32bit (suggested by 0-day kbuild bot).
- Remove sysfs attributes ext_current_lim and ext_voltage_lim because
  I don't know yet where they should be placed (and don't have HW to
  test them).
- Remove superfluous pre-allocated buffers ec_inbuf and ec_outbuf.
- Lots of misc comments from Stephen Boyd were addressed.
- Unregister notification listener in .remove callback.
- Only register the PD charger device if there are any PD ports in this
  EC.
- Dropped patch using EC_CMD_GET_FEATURES to decide whether to create a
  charger device because we are now only creating one if a EC has any PD
  ports.
- Dropped patch adding power_supply types because it has been merged
  already.

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.
- 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.
