Subject: [PATCH] tools/hciattach_ath3k: Load BT board data based on country code
Date:   Mon, 30 Mar 2020 17:33:55 -0700
Message-Id: <20200331003355.14614-1-sonnysasaka@chromium.org>
Sender: linux-bluetooth-owner@vger.kernel.org
Precedence: bulk

BT board data file PS_ASIC-<country-code>.pst is loaded based
on country code. If not exist, default BT board data file
PS_ASIC.pst would be loaded.

This patch doesn't define how to get the country code at the moment, but
future patches can supply the country code in the region parameter of
get_ps_file_name.
