Date: Sun, 27 Mar 2011 17:46:32 +0800 Message-Id: <1301219192-5293-1-git-send-email-wanlong.gao@gmail.com> X-Mailer: git-send-email 1.7.3 Sender: linux-kernel-owner@vger.kernel.org List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Content-Length: 3519 Lines: 107 From: Wanlong Gao Many touchscreens support touch-keypad . Open the definition of the TOUCHSCREEN_TSC2007_WITH_KEYPAD, you can open the support of the touchscreen's keypad . We can add the support of the touchscreen keypad in the driver. In this patch , add the ts_key_pos array to determine the position of the key's X. And the ts_key_sensitivity can use to detemine the key's sensitivity. You can modify the ts_key_pos array for you own touchscreen keys . And modify the ts_key_sensitivity for you own key's sensitivity . If you want to modify the ts_key_map, change the position of the keys ,too.
