From f826caa44902ddbe93174f0b642d8abf9698c08e Mon Sep 17 00:00:00 2001 From: Haavard Skinnemoen Date: Sun, 24 Feb 2008 14:34:45 +0100 Subject: atmel_serial: Fix build on avr32 with CONFIG_PM enabled AVR32 doesn't have at91_suspend_entering_slow_clock(). Just assume the clock will keep running for now. David has a better solution for this, but this works for now. Leaving the USART clock running won't prevent the PM code from entering deep power-down modes anyway.
