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. This series may be best integrated through the MFD tree, for which we'll need ACKs from Olof (for the changes to platform/chrome), from Dmitry (for changes to cros_ec_keyb.c) and from Sebastian Reichel for the new driver. Thanks, Tomeu Changes in v6: - Return 0 if the EC doesn't support MKBP, as expected by callers. Changes in v5: - Check explicitly for !EC_RES_SUCCESS as suggested by Benson Leung. - Fix type of variable passed to do_div. Changes in v4: - Calculate correctly the size of the payloads in cros_ec_get_host_command_version_mask. - Declare size parameters in ec_command as size_t 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.
