From 9d32c30542f9ecdb4b96a1a960924c9f403e3562 Mon Sep 17 00:00:00 2001 From: H Hartley Sweeten Date: Mon, 5 Apr 2010 22:29:09 -0700 Subject: [PATCH] Input: matrix_keypad - allow platform to disable key autorepeat In an embedded system the matrix_keypad driver might be used to interface with an external control panel and not an actual keyboard. On the control panel some of the keys could be used to turn on/off various functions. If key autorepeat is enabled this causes the function to quickly toggle between the on and off states and makes operation difficult. Add an option in the platform-specific data to disable the key autorepeat.
