* ARM: 7366/3: amba: Remove AMBA level regulator supportMark Brown2012-04-13
| | | | | | | | | | | | | | | | | | | | | | | | | | 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. We'll find out anything that got broken and fix it.. * tag 'split-asm_system_h-for-linus-20120328' of git://git.kernel.org/pub/scm/linux/kernel/git/dhowells/linux-asm_system: (38 commits) Delete all instances of asm/system.h Remove all #inclusions of asm/system.h Add #includes needed to permit the removal of asm/system.h Move all declarations of free_initmem() to linux/mm.h Disintegrate asm/system.h for OpenRISC Split arch_align_stack() out from asm-generic/system.h Split the switch_to() wrapper out of asm-generic/system.h Move the asm-generic/system.h xchg() implementation to asm-generic/cmpxchg.h Create asm-generic/barrier.h Make asm-generic/cmpxchg.h #include asm-generic/cmpxchg-local.h Disintegrate asm/system.h for Xtensa Disintegrate asm/system.h for Unicore32 [based on ver #3, changed by gxt] Disintegrate asm/system.h for Tile Disintegrate asm/system.h for Sparc Disintegrate asm/system.h for SH Disintegrate asm/system.h for Score Disintegrate asm/system.h for S390 Disintegrate asm/system.h for PowerPC Disintegrate asm/system.h for PA-RISC Disintegrate asm/system.h for MN10300 ...

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | twl4030 is using a two level irq controllers infrastruture. 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.

| * | mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq filesBenoit Cousson2012-03-22

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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In the case we go to the retention mode, we decoupled the gic in order to have the A9 core to reach a stable WFI state. But we want the prcmu to wake up the A9 when the gic has a pending irq which is done by copying the gic settings to the to the prcmu.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch introduces a routine to check if there are some irqs pending on the gic. Usually this check is not relevant because it appears racy (an irq can arrive right after this check), but in the ux500 it makes sense because the prcmu decouples the gic from the A9 cores.

Now introduce a voting mechanism to enable/disable it. Add pm8606_osc_enable() and pm8606_osc_disable() interface and related defines to support this. This interface will be called by vibrator led and backlight driver.The refernce group and internal oscillator are enabled only when at least one of it's clients holds it on or disabled only all the clients don't use it any more based on the above mechanism.

Enabling caching of the registers which is used for voltage controls. By doing this, the modify_bits operation is faster as it does not involve the i2c register read from device, just read from cache. This results faster set voltage operation.

However, any write(0 or 1) to register INT_STS_A, INT_STS_B or INT_STS_C clears all 3 interrupt status registers. Since clear of the interrupt is done on 32k clk, depending on I2C bus speed, we could in-adverently clear the status of a interrupt status pending on shadow register in the current implementation. This is due to the fact that multi-byte i2c write operation into three seperate status register could result in multiple load and clear of status and result in lost interrupts. Instead, doing a single byte write to INT_STS_A register with 0x0 will clear all three interrupt status registers without the related risk.
