Subject: [PATCH v9 1/3] Bluetooth: hci_uart: add prepare callback
Date: Fri, 29 Apr 2016 03:24:36 -0700	[thread overview]
Message-ID: <1461925478-31851-1-git-send-email-akarwar@marvell.com> (raw)

From: Ganapathi Bhat <gbhat@marvell.com>

This new uart protocol callback is used to prepare the device before
HCI becomes ready. One can use this to download firmware if the
download process doesn't use HCI commands.
