2011-03-15davinci: DM644x EVM: register MUSB device earlierSergei Shtylyov1-5/+3
The MUSB driver doesn't see its platform device on DM644x EVM board anymore since commit 73b089b052a69020b953312a624a6e1eb5b81fab (usb: musb: split davinci to its own platform_driver) because the new probe is called as subsys_initcall() now, and the device is registered later than that by the board code. Move the registration to davinci_evm_init() -- it's safe to do so because the MUSB core device still gets initialized as fs_initcall() -- which is late enough for the I2C GPIO expander (which controls VBUS) to be initialized.

2011-03-15ARM: EXYNOS4: Implement Clock gating for System MMUKyongHo Cho5-11/+117
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: Add support for gpio interruptsMarek Szyprowski2-5/+25
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 Szyprowski4-10/+76
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: 6806/1: irq: introduce entry and exit functions for chained handlersWill Deacon1-0/+31
Some chained IRQ handlers are written to cope with primary chips of potentially different flow types. Whether this a sensible thing to do is a point of contention. This patch introduces entry/exit functions for chained handlers which infer the flow type of the primary chip as fasteoi or level-type by checking whether or not the ->irq_eoi function pointer is present and calling back to the primary chip as necessary. Other methods of flow control are not considered.

2011-03-14arm: Remove bogus comment in futex_atomic_cmpxchg_inatomic()Thomas Gleixner1-3/+0
commit 522d7dec(futex: Remove redundant pagefault_disable in futex_atomic_cmpxchg_inatomic()) added a bogus comment. /* Note that preemption is disabled by futex_atomic_cmpxchg_inatomic * call sites. */ Bogus in two aspects: 1) pagefault_disable != preempt_disable even if the mechanism we use is the same 2) we have a call site which deliberately does not disable pagefaults as it wants the possible fault to be handled - though that has been changed for consistency reasons now.

2011-03-14omap: iovmm: don't check 'da' to set IOVMF_DA_FIXED flagDavid Cohen2-11/+5
Currently IOVMM driver sets IOVMF_DA_FIXED/IOVMF_DA_ANON flags according to input 'da' address when mapping memory: da == 0: IOVMF_DA_ANON da != 0: IOVMF_DA_FIXED It prevents IOMMU to map first page with fixed 'da'. To avoid such issue, IOVMM will not automatically set IOVMF_DA_FIXED. It should now come from the user throught 'flags' parameter when mapping memory. As IOVMF_DA_ANON and IOVMF_DA_FIXED are mutually exclusive, IOVMF_DA_ANON can be removed. The driver will now check internally if IOVMF_DA_FIXED is set or not.

Setting pinmux alternative C for a GPIO pin is actually not so easy since it ivolves setting value "1" in two registers, and since the combined result will take effect for intermediate values (01 or 10) this will cause glitches while you wrote one register but have not yet written the other.
