From 7be90a6ba996e43902fc89704b60a57fd4659a63 Mon Sep 17 00:00:00 2001 From: Stelian Pop Date: Wed, 22 Oct 2008 13:52:08 +0100 Subject: [ARM] 5319/1: AT91: support AT91CAP9 revC CPUs The AT91CAP9 revC CPU has a few differences over the previous, revB CPU which was distributed in small quantities only (revA was an internal Atmel product only). This patch adds the detection routines to recognize the different AT91CAP9 revisions (based on the PMC subsystem version number), and uses them to: - activate a workaround for the external interrupts levels (on revB CPUs) - set the UDPHS_BYPASS bit (on revB CPUs) - set AT91_GPBR register address to the correct offset (0xfffffd50 on revB, 0xfffffd60 on revC) For debugging usage, the CPU revision can be found in /proc/cpuinfo on the 'Revision' line. This patch is extracted from Andrew Victor's -at91 patch (2.6.27-at91.patch) where it has been tested for the last 6 months.
