This driver uses regmap_irq APIs, thus need to select REGMAP_IRQ. IRQ_DOMAIN will be selected if select REGMAP_IRQ, thus remove it here.

2012-12-03mfd: arizona: Defer patch initialistation until after first device bootMark Brown1-5/+12
Make sure that we don't race with the initial device boot by only doing the initialisation after we've waited for the boot to complete. The runtime PM code already waits for the boot to complete before it syncs the register patches so in most systems if a race does occur we will power down very soon afterwards and recover anyway.

2012-11-30mfd: tps65910: Fix wrong ack_base registerKim, Milo1-2/+2
The interrupt status registers of TPS65910/1 should be cleared when the associated interrupt event occurs. This work is done in the regmap irq thread - using 'ack_base' register. The ACK registers should be fixed as status register, not mask registers. This patch fixes the infinite interrupt event problem by clearing interrupt status registers.

2012-11-30mfd: tps65910: Remove unused dataKim, Milo2-3/+0
The 'io_mutex' is not used anywhere. The regmap API supports the mutex internally, so no additional mutex is required. And 'domain' private data is unnecessary because the irq domain is already registered by using regmap_add_irq_chip().

Since the very first patch, stmpe core driver is using irq_invert_polarity as part of platform data. But, nobody is actually using it in kernel till now. Also, this is not something part of hardware specs, but is included to cater some board mistakes or quirks. So, better get rid of it.
