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.

2011-03-15ARM: EXYNOS4: Enhancement of System MMU driverKyongHo Cho
This patch includes the following enhancements for System MMU: - Enhanced readability - Removal of unused data structures or their members - Simplified function definitions - Corrections of some logical errors - Full compliance with Linux coding style - Simpler way of registering callback functions of System MMU faults Signed-off-by: KyongHo Cho <pullip.cho@samsung.com> Signed-off-by: Kukjin Kim <kgene.kim@samsung.com>
2011-03-15ARM: EXYNOS4: Add support for gpio interruptsMarek Szyprowski
This patch adds support for gpio interrupts on Samsung EXYNOS4 platform. Common s5p-gpioint.c code is used for handling gpio interrupts. Each gpio line that needs gpio interrupt support must be later registered with s5p_register_gpio_interrupt() function.

2011-03-15ARM: S5P: Add function to register gpio interrupt bank dataMarek Szyprowski
This patch removes all global data from common s5p gpio interrupt handler code. This enables to reuse this code on EXYNOS4 platform. Instead of global data (IRQ_GPIOINT interrupt number, S5P_GPIOINT_GROUP_MAXNR groups count), a s5p_register_gpioint_bank() function is introduced. It is aimed to be called from gpiolib init.

2011-03-15ARM: S5P: Cleanup S5P gpio interrupt codeMarek Szyprowski
This patch performs a global cleanup in s5p gpio interrupt support code. The code is prepared for upcoming support for gpio interrupts on EXYNOS4 platform, which has 2 gpio banks (regions) instead of one (like on S5PC110 and S5PC100).

Andi Kleen narrowed his GPU hangs on his Sugar Bay (SNB desktop) rev 09 down to the use of GPU semaphores, and we already know that they appear broken up to Huron River (mobile) rev 08. (I'm optimistic that disabling GPU semaphores is simply hiding another bug by the latency and side-effects of the additional device interaction it introduces...) However, use of semaphores is a massive performance improvement... Only as long as the system remains stable. Enable at your peril.
