From b56ece9a3ac3c9708b8f1cebf4ba24c258d40e52 Mon Sep 17 00:00:00 2001 From: Daniel Drake Date: Sun, 30 Jun 2013 18:37:24 -0700 Subject: Input: add OLPC AP-SP driver The OLPC XO-1.75 and XO-4 laptops include a PS/2 touchpad and an AT keyboard, yet they do not have a hardware PS/2 controller. Instead, a firmware runs on a dedicated core ("Security Processor", part of the SoC) that acts as a PS/2 controller through bit-banging. Communication between the main cpu (Application Processor) and the Security Processor happens via a standard command mechanism implemented by the SoC. Add a driver for this interface to enable keyboard/mouse input on this platform.
