Subject: [PATCH v4 3/5] usb: host: xhci-plat: support override of hc driver
Date: Tue, 26 Apr 2022 18:18:46 +0900 [thread overview]
Message-ID: <1650964728-175347-4-git-send-email-dh10.jung@samsung.com> (raw)
In-Reply-To: <1650964728-175347-1-git-send-email-dh10.jung@samsung.com>
It helps xhci-plat driver increase usability. Vendors could use functions
in xhci-plat mostly and use some overrides to do what they wants without
modifying xhci-plat driver.
