2012-03-22ARM: OMAP2+: board-omap4-*: Do not use anymore TWL6030_IRQ_BASE in board filesBenoit Cousson
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 Cousson
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code using a statically allocated IRQ scheme: card_detect_irq = TWL6030_IRQ_BASE + MMCDETECT_INTR_OFFSET; This is no longer valid in a SPARSE_IRQ context since there is no more pre-defined TWL6030_IRQ_BASE.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 Vincent
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 : Copy the db8500 gic setting to the prcmuDaniel Lezcano
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.

2012-03-06mfd : Check if there are pending irq on the db8500 gicDaniel Lezcano
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.

2012-03-06mfd: Clear twl6030 IRQ status register only onceNishanth Menon
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.
