From ef53a1159dfcdc1fecf5adb5b8d26803f194c09b Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 27 Nov 2009 22:01:23 -0300 Subject: V4L/DVB (13532): ir-common: Add infrastructure to use a dynamic keycode table V4L drivers use an static keycode vector with 128 entries, where the scancode indexes the keycode. While this works, it limits the scancodes to have only 7 bits, not allowing for example full RC5 codes. Instead of implementing the same code on every V4L driver, provide a common infrastructure to handle the bigger tables, minimizing the changes inside each driver.
