From eb17380972d563a7dd59634cd2fdb614f3b98cdd Mon Sep 17 00:00:00 2001 From: Loic Poulain Date: Wed, 25 Mar 2015 15:19:30 +0100 Subject: Bluetooth: hci_uart: Add setup callback Some Bluetooth controllers require initialization before being used (vendor config, firmware download). Add possibility for a HCI UART proto to implement this early init via the setup callback.
