From 470f22975448a65a1084a6f0721fa5df15323f02 Mon Sep 17 00:00:00 2001 From: Boojin Kim Date: Fri, 27 May 2011 19:04:03 -0700 Subject: ARM: SAMSUNG: serial: Fix on handling of one clock source for UART This patch fixes the way of comparison for handling of two or more clock sources for UART. For example, if just only one clock source is defined even though there are two clock sources for UART, the serial driver does not set proper clock up. Of course, it is problem. So this patch changes the condition of comparison to avoid useless setup clock and adds a flag 'NO_NEED_CHECK_CLKSRC' which means selection of source clock is not required. In addition, since the Exynos4210 has only one clock source for UART this patch adds the flag into its common_init_uarts().
