[PATCH v2 13/14] i2c-cht-wc: Add device-properties for fusb302 integration

Add device-properties to make the bq24292i charger connected to the bus get its input-current-limit from the fusb302 Type-C port controller which is used on boards with the cht-wc PMIC, as well as regulator_init_data for the 5V boost converter on the bq24292i. Since this means we now hook-up the

[PATCH v2 14/14] platform/x86: intel_cht_int33fe: Update fusb302 type string, add properties

The fusb302 driver as merged in staging uses "typec_fusb302" as i2c-id rather then just "fusb302" and needs us to set a number of device- properties, adjust the intel_cht_int33fe driver accordingly. One of the properties set is max-snk-mv which makes the fusb302 driver negotiate up to 12V

[PATCH v2 11/14] power: supply: bq24190_charger: Get input_current_limit from our supplier

On some devices the USB Type-C port power (USB PD 2.0) negotiation is done by a separate port-controller IC, while the current limit is controlled through another (charger) IC. It has been decided to model this by modelling the external Type-C power brick (adapter/charger) as a power-supply class

[PATCH v2 12/14] power: supply: bq24190_charger: Remove extcon handling

Now that drivers/i2c/busses/i2c-cht-wc.c uses "input-current-limit-from-supplier" instead of "extcon-name" the last user of the bq24190 extcon code is gone, remove it. Signed-off-by: Hans de Goede --- Changes in v2: -Move the comment with the example code for passing
