Subject: [PATCH] platform/chrome: cros_usbpd_notify: Listen to EC_HOST_EVENT_USB_MUX host event
Date: Wed, 14 Apr 2021 14:45:24 +0800 [thread overview]
Message-ID: <20210414064524.2450908-1-pihsun@chromium.org> (raw)
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.
