From 865d605ee81813dc73d5422fd2f9bd132d10d194 Mon Sep 17 00:00:00 2001 From: Jamie Iles Date: Tue, 9 Aug 2011 16:51:11 +0200 Subject: at91: provide macb clks with "pclk" and "hclk" name The macb driver expects clocks with the names "pclk" and "hclk". We currently provide "macb_clk" but to fit in line with other architectures (namely AVR32), provide "pclk" and a fake "hclk".

2011 09:53:29 +0000 Subject: ARM: restart: at91: use new restart hook Rather than using a private function pointer, use the existing arm_pm_restart function pointer instead. We no longer need to enable the I-cache in at91sam9_alt_reset() as the caches will now be on when this function is called. Update the function names to use the 'restart' terminology rather than the 'reboot' terminology.
