From 69ebb22277a53f612ccd632ceb73ed87c9093412 Mon Sep 17 00:00:00 2001 From: Kristoffer Ericson Date: Fri, 20 Jul 2007 18:22:57 +0100 Subject: [ARM] 4506/1: HP Jornada 7XX: Addition of SSP Platform Driver These patches add full SSP/MCU support for the HP Jornada 720 machine. Its needed to handle keyboard, touchscreen, battery and backlight/lcd. The main driver exports functions and the header file exports the command values. When talking to the MCU the general procedure is to start MCU, send command (using ssp_inout(command)), the proper reply is always TXDUMMY. After receiving TXDUMMY you can send the value you wish pushed (for example brightness level). End with ssp_end() so the spinlock gets unlocked. Drivers using this havent been implemented yet, but will shortly.
