From c7c8c78fdf6e9bd65d8ee879115dc2cd5d9fd0dc Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 14 Aug 2009 10:59:05 +0100 Subject: ARM: 5667/3: U300 SSP/SPI board setup and test This adds a U300 board configuration for the PL022 SSP/SPI PrimeCell driver recently merged to the 2.6.31-rc series. Further it adds a dummy loopback SPI chip that can be used for testing the SPI functionality on a running system using the loopback mode of PL022.
