2012-03-22mfd: Make twl4030 SIH SPARSE_IRQ capableBenoit Cousson3-19/+9
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.

2012-03-22mfd: Move twl-core IRQ allocation into twl[4030|6030]-irq filesBenoit Cousson4-37/+56
During DT adaptation, the irq_alloc_desc was added into twl-core, but due to the rather different and weird IRQ management required by the twl4030, it is much better to have a different approach for it. 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.

With the introduction of dynamically allocated IRQ in the twl6030 driver, the board files can no longer rely of static IRQ defines like before. Retrieve the value dynamically allocated from the mmc -> twl6030 init callback. Note: The Panda board does not seems to use the card detect IRQ.

2012-03-22mfd: Return twl6030_mmc_card_detect IRQ for board setupBenoit Cousson1-1/+2
Card detect IRQ from the TWL6030 used to be provided to the MMC controller code using a statically allocated IRQ scheme: card_detect_irq = TWL6030_IRQ_BASE + MMCDETECT_INTR_OFFSET; This is no longer valid in a SPARSE_IRQ context since there is no more pre-defined TWL6030_IRQ_BASE. Return the proper card detect IRQ value in the twl6030_mmc_card_detect_config that will be called from the MMC controller.

2012-03-16mfd: Don't use mutex_lock_interruptible in ab8500-coreRabin Vincent1-9/+3
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.

2012-03-06mfd: Clear twl6030 IRQ status register only onceNishanth Menon1-2/+11
TWL6030 family of PMIC use a shadow interrupt status register while kernel processes the current interrupt event. 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.
