From bd3143f040ab186f8b665b3ada35840e3fc491e9 Mon Sep 17 00:00:00 2001 From: Wolfgang Denk Date: Wed, 19 Jul 2006 14:49:35 +0200 Subject: [PATCH] Fix support for PS/2 keyboard on TQM85xx boards The PS/2 keyobard driver for the TQM85xx modules only supports the internal DUART of the MPC85xx CPU. Since the MPC8560 doesn't include a DUART, the TQM8560 modules can't be used with the PS/2 keyboard controller on the STK85xx board. The PS/2 keyboard driver should work with the modules TQM8540, TQM8541 and TQM8555, but it only has been tested on a TQM8540, yet. Make sure the PS/2 controller on the STK85xx is programmed.
