From 582798b5c6c3ae0e53f099dc516a025b9d8589fd Mon Sep 17 00:00:00 2001 From: Vasily Khoruzhick Date: Tue, 15 Feb 2011 15:27:29 +0200 Subject: [PATCH] pxa2xx_keypad: Handle 0xe0xx keycodes Add handling of 0xe0xx keycodes to pxa2xx_driver. Extended keycodes in keymap should be marked with most significant bit set (i.e. 0x80). Without this patch it's not possible to handle i.e. cursor keys.
