[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. Signed-off-by: Kristoffer Ericson <Kristoffer.ericson@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>

[ARM] 5255/1: Update jornada ssp to remove build errors/warnings * Adds ssp functions into header so we don't get "implicit declaration" error at builtime. * Converts jornada_ssp_start/end functions into voids with proper declarations (to avoid "prototype..." warning). * Sorts include files in alphabetical order * Minor comment changes Signed-off-by: Kristoffer Ericson <Kristoffer.Ericson@gmail.com> Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
