2011-06-07ARM: SAMSUNG: serial: Fix on handling of one clock source for UARTBoojin Kim
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().

2011-03-15ARM: EXYNOS4: Implement Clock gating for System MMUKyongHo Cho
This patch includes the implementation of the clock gating for System MMU. Initially, all System MMUs are not asserted the system clock. Asserting the system clock to a System MMU is enabled only when s5p_sysmmu_enable() is called. Likewise, it is disabled only when s5p_sysmmu_disable() is called. Therefore, clock gating on System MMUs are still invisible to the outside of the System MMU driver.
