From 205bee6ad804d7034773b5978c74dde495df2301 Mon Sep 17 00:00:00 2001 From: Russell King Date: Sun, 20 Apr 2008 13:57:26 +0100 Subject: [ARM] dyntick: Remove obsolete and unused ARM dyntick support dyntick is superseded by the clocksource/clockevent infrastructure, using the NO_HZ configuration option. No one implements dyntick on ARM anymore, so it's pointless keeping it around. Remove dyntick support.

This is patch 2 of 2 adding support for the USB High Speed Device Port on the AT91CAP9 system on chip. The AT91CAP9 uses the same UDPHS IP as the AVR32 and the AT91SAM9RL. This patch declares the UDPHS ressources in the at91cap9 (cpu and adk board) files, wires up the atmel_usba_udc driver to them, and activates the driver in the defconfig.
