If anyone has any objections, please let me know. ------------------ From: Derek Fang [ Upstream commit 103abab975087e1f01b76fcb54c91dbb65dbc249 ] The codec leaves tie combo jack's sleeve/ring2 to floating status default. It would cause electric noise while connecting the active speaker jack during boot or shutdown. This patch requests a gpio to control the additional jack circuit to tie the contacts to the ground or floating.
