platform/chrome: cros_ec_lpc: Use DEFINE_MUTEX() for mutex lock

2021-04-21T08:00:30Z

mutex lock can be initialized automatically with DEFINE_MUTEX() rather than explicitly calling mutex_init(). Reported-by: Hulk Robot Signed-off-by: Ye Bin Signed-off-by: Enric Balletbo i Serra Link: https://lore.kernel.org/r/20210409095138.2293869-1-yebin10@huawei.com

platform/chrome: cros_usbpd_notify: Listen to EC_HOST_EVENT_USB_MUX host event

2021-04-21T07:40:37Z

On system that use ACPI, cros_usbpd_notify gets notifications of USB MUX host event same as PD host events [1]. But currently on system that use DT, the driver only listen on EC_HOST_EVENT_PD_MCU. Add EC_HOST_EVENT_USB_MUX to the list of host events, so we have same behavior on all platforms.

platform/chrome: cros_ec_typec: Add DP mode check

2021-04-21T07:33:35Z

There are certain transitional situations where the dp_mode field in the PD_CONTROL response might not be populated with the right DP pin assignment value yet. Add a check for that to avoid sending an invalid value to the Type C mode switch.

platform/chrome: cros_ec_typec: Handle hard reset

2021-04-20T17:35:42Z

The Chrome Embedded Controller (EC) generates a hard reset type C event when a USB Power Delivery (PD) hard reset is encountered. Handle this event by unregistering the partner and cable on the associated port and clearing the event flag.

platform/chrome: cros_ec_typec: Track port role

2021-04-20T17:35:42Z

Stash the currently reported port role in the port struct and add a check for that too while determining whether to re-configure on-board Type C switches (this deals with cases like role swaps where the mux flags don't change, but the port role does).

The older device property API is going to be removed soon and that will affect also I2C subystem. Supplying complete software nodes instead of only the properties in them for the I2C devices. Signed-off-by: Heikki Krogerus Acked-by: Enric Balletbo i Serra Signed-off-by: Wolfram Sang

platform/chrome: cros_ec_typec: Check for device within remove function

2021-03-30T16:25:22Z

In a couple of call sites, we use the same pattern of checking for a partner or cable device before attempting to remove it. Simplify this by moving those checks into the remove functions.
