Changes in v2:
- converted sysfs debug exports into debugfs
- added kernel-doc comments for exposed functions
- fixed minor typos and inconsistencies

Changes in v3:
- dropped DockRAM commits (both schema and driver)
- integrated DockRAM functionality directly into the controller driver
- EC schema moved to embedded controllers folder
- removed all cell descriptions from the schema
- removed all compatibles from the cell drivers
- adjusted naming conventions to better align with the ASUS Transformers
- defined EC variant sets to provide coverage for all known devices

Changes in v4:
- grouped known programming models of EC chronologically (both schema
  and driver)
- call debugfs init only if CONFIG_DEBUG_FS is enabled

Changes in v5:
- added asus,tf600t-ec-dock compatible to schema
- rebased on top of v7.0
- kzalloc > kzalloc_obj in keys and kbc

Changes in v6:
- removed asus_ec_handle_smi casting
- asus_dockram_access_ctl > asus_ec_get_ctl in control_reg_*
- fixed battery Kconfig description

Changes in v7:
- added status check of devm_kasprintf where missing
- devm_asus_ec_register_notifier dropped, added .remove where it was used
- removed cell_to_ec, asus_dockram_read, asus_dockram_write, asus_ec_* public API
  asus_ec_i2c_command, devm_asus_ec_register_notifier, asus_ec_read, asus_ec_write
- renamed asusec_info > asusec_core
- ec-kbc: added packed size check
	  ret > error
	  improved key remap logic
- ec-keys: improve formatting and comments 
	   ret > error
	   switched to dev_err_probe
- ec-leds: reworked to register both leds via loop
- ec-mfd: adjusted Kconfig description
	  fixed smbus operation sizes
	  fixed saving of EC fw model
	  adjusted IRQ flags
	  converted to use definer for set cell composition
	  added factory mode states enum and handling
	  defined some "magic" values
	  self > client, info > ec, ecreq > ecreq_gpio, priv > ddata
	  asus_ec_chip_data data > asus_ec_chip_info info
	  ec_data > ec_buf, ctl_data > ctl_buf
	  added and improved comments, added structure descriptions
	  asus_ec_magic_debug > asus_ec_susb_on_status
	  removed all dev_dbg and most of dev_info
	  pronts with model, fw behavior, factory and susb state preserved
	  switched to MFD_CELL_* macros
	  removed debugfs
- ec-battery: swithced to BIT macro
	      lock usage moved to asus_ec_battery_get_value
	      in asus_ec_battery_poll_work fixed possible rescheduling fail
	      in asus_ec_battery_poll_work fixed missing not charging
- ec-charger: POWER_SUPPLY_PROP_MODEL_NAME set as the first check
