From 83e81961ff7ef75f97756f316caea5aa6bcc19cc Mon Sep 17 00:00:00 2001 From: Ben Young Tae Kim Date: Mon, 10 Aug 2015 14:24:12 -0700 Subject: Bluetooth: btqca: Introduce generic QCA ROME support This is for supporting BT for QCA ROME with vendor specific HCI commands and initialization on the chip. This will have USB/UART implementation both, but for now, adding UART vendor specific commands to patch downloading and set Bluetooth device address using vendor specific command.
