Subject: board: asus: tf700t: bind tc358768 bridge and panel
X-Git-Url: http://git.dujemihanovic.xyz/contact?a=commitdiff_plain;h=d1db2733a50176f40943b64efbab3222c981899a;p=u-boot.git

board: asus: tf700t: bind tc358768 bridge and panel

Of all T30 transformers, only the TF700T has a FullHD DSI panel,
which is connected via tc358768 RGB to DSI bridge. Since the
bridge driver is available now, TF700T can have video support.
