2013-09-02mfd: twl6040: Use regmap for register cacheMark Brown
Rather then open coding a cache of the vibra control registers use the regmap cache code. Also cache the interrupt mask register, providing a small performance improvement for the interrupt code.

2013-08-30mfd: mmc: rtsx: Change default tx phaseWei WANG
The default phase can meet most cards' requirement, but it is not the optimal one. In some extreme situation, the rx phase point produced by the following tuning process will drift quite a distance. Before tuning UHS card, this patch will set a more proper initial tx phase point, which is calculated from statistic data, and can achieve a much better tx signal quality.

2013-08-20mfd: twl6030-irq: Convert to use linear irq_domainGrygorii Strashko
Since the TWL6030 PMIC is used with OMAP4 SoCs only and OMAP4 legacy boot is dropped there are no needs to allocate the range of IRQ descriptors during system boot to support TWL6030 IRQs. Hence, convert it to use linear irq_domain and move IRQ configuration in .map()/.unmap() callbacks of irq_domain. So, IRQ mapping and descriptors allocation will be performed dynamically basing on DT configuration. The error message will be reported in case if unmapped IRQ is received by TWL6030 (virq==0).

2013-08-20mfd: twl6030-irq: Migrate to IRQ threaded handlerNaga Venkata Srikanth V
1) Removed request_irq() and replaced it with request_threaded_irq(). 2) Removed generic_handle_irq() and replaced it with handle_nested_irq(). Handling of these interrupts is nested, as we are handling an interrupt (for e.g rtc, mmc1) when we are still servicing TWL irq. 3) Removed I2C read-retry logic for the case when twl_i2c_read() is failed inside IRQ handler - there is no sense to do that, so just report an error and return. 4) Each nested IRQ is configured with corresponding parent_irq, which need to be retriggered in case if nested IRQ is marked as IRQS_PENDING.
