* mfd: Fix build breakage in omap-usb-host.cRuss Dill2012-05-011-0/+1
| | | | | | | | | | | | | 'ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issue' removes the include for linux/gpio.h from omap-usb-host.c. This include indirectly includes plat/cpu.h which is required by omap-usb-host.c. Fix the build breakage by including it directly.

* mfd: Fix asic3_gpio_to_irqDmitry Artamonow2012-04-161-1/+3
| | | | | | | | | | | | | | | | | | | | | Assumption that irq numbers of asic3 gpios start at IRQ_BOARD_START is certainly wrong - driver may as well use any other base for its irqs (consider for example the imaginary case of two ASIC3 chips onboard) Furthermore, some platforms even don't have IRQ_BOARD_START defined, so driver will fail to build on them: ------------------------------------------------------- drivers/mfd/asic3.c: In function 'asic3_gpio_to_irq': drivers/mfd/asic3.c:530: error: 'IRQ_BOARD_START' undeclared (first use in this function) drivers/mfd/asic3.c:530: error: (Each undeclared identifier is reported only once drivers/mfd/asic3.c:530: error: for each function it appears in.) ------------------------------------------------------- Fix it by using irq_base from driver data.

* ARM: OMAP3: USB: Fix the EHCI ULPI PHY reset issueKeshava Munegowda2012-04-161-44/+0Star
| | | | | | | | | | | | | | | | | | | It is observed that the echi ports of 3430 sdp board are not working due to the random timing of programming the associated GPIOs of the ULPI PHYs of the EHCI for reset. If the PHYs are reset at during usbhs core driver, host ports will not work because EHCI driver is loaded after the resetting PHYs. The PHYs should be in reset state while initializing the EHCI controller. The code which does the GPIO pins associated with the PHYs are programmed to reset is moved from the USB host core driver to EHCI driver.

* ARM: 7366/3: amba: Remove AMBA level regulator supportMark Brown2012-04-131-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | The AMBA bus regulator support is being used to model on/off switches for power domains which isn't terribly idiomatic for modern kernels with the generic power domain code and creates integration problems on platforms which don't use regulators for their power domains as it's hard to tell the difference between a regulator that is needed but failed to be provided and one that isn't supposed to be there (though DT does make that easier). Platforms that wish to use the regulator API to manage their power domains can indirect via the power domain interface. This feature is only used with the vape supply of the db8500 PRCMU driver which supplies the UARTs and MMC controllers, none of which have support for managing vcore at runtime in mainline (only pl022 SPI controller does). Update that supply to have an always_on constraint until the power domain support for the system is updated so that it is enabled for these users, this is likely to have no impact on practical systems as probably at least one of these devices will be active and cause AMBA to hold the supply on anyway.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

So far, only the first level was using dynamic irq_desc allocation to be able to have irq_domain support for device tree. There is a need to allocate separate irq_descs for the SIH too to avoid hacking the first level with interrupts from the second level. Add an irq_base parameter to allow the caller to provide the base from pdata or from dynamic allocation. Affect TWL4030_NR_IRQS to the twl-core IRQs only. Moreover that will allow the extraction of the of_node pointer for further Device Tree conversion.

The issue is that twl4030 uses a two level IRQ mechanism but handles all the PWR interrupts as part of the twl-core interrupt range. It ends up with a range of 16 interrupts total for CORE and PWR. The other twl4030 functionalities already have a dedicated driver and thus their IRQs and irqdomain can and should be defined localy. twl6030 is using a single level IRQ controller and thus does not require any trick. Move the irq_alloc_desc and irq_domain_add_legacy in twl4030-irq and twl6030-irq. Allocate together CORE and PWR IRQs for twl4030-irq.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This disadvantage of having it interruptible is that it would appear to work OK in most situations, but in the rare case that this call does fail, it can lead to misconfiguration of the AB, such as a regulator not being turned off and leading to a platform power consumption increase. There's no real benefit to having this interruptible. Make it a plain mutex_lock. The non-interruptability matches other low-level I/O functions such as SPI and I2C.
