Subject: [PATCH v2 0/2] add hooks for usb suspend and resume
Date: Wed, 14 Dec 2022 16:14:54 +0800 [thread overview]
Message-ID: <20221214081456.714859-1-pumahsu@google.com> (raw)
In mobile, a co-processor can be used for USB audio. When the co-processor
is working for USB audio, the co-processor is the user/owner of the USB
driver, and the ACPU is able to sleep in such condition to improve power
consumption. In order to support this, we need to create hooks in suspend
and resume functions. We also upload our implementations for reviewing.
