[PATCH 0/2] mfd: cros_ec_dev: Add gpio device and DT binding

[Stephen Boyd]

This is the mfd part of a larger series[1] that describes the USB
topology on ARM based chromebooks. These two patches add the gpio device
and DT bindings when the GPIO feature is present. The gpio driver will
be sent separately.

[PATCH 1/2] dt-bindings: cros-ec: Add properties for GPIO controller

[Stephen Boyd]

The ChromeOS embedded controller (EC) supports setting the state of
GPIOs when the system is unlocked, and getting the state of GPIOs in all
cases. The GPIOs are on the EC itself, so the EC acts similar to a GPIO
expander. Add the #gpio-cells and gpio-controller properties to the
cros-ec binding so that other devices described in DT can get the GPIOs
on the EC.

[PATCH 2/2] mfd: cros_ec_dev: Add gpio device if feature present on EC

[Stephen Boyd]

The ChromeOS embedded controller (EC) supports setting the state of
GPIOs when the system is unlocked, and getting the state of GPIOs in all
cases. Check for the feature support by checking for the GPIO feature
and then populate a sub-device for the gpio hardware on the EC.
