2013-08-20mfd: rtsx: Add shutdown callback in rtsx_pci_driverWei WANG
Some actions to clear power state should be handled in .shutdown callback in rtsx_pci_driver. This patch adopts the following measures to catch this goal: 1. Add a function rtsx_pci_power_off to abstract the common ops in .shutdown and .suspend 2. Add pcr->ops->force_power_down to fulfill the individual action for each reader model Signed-off-by: Wei WANG <wei_wang@realsil.com.cn> Signed-off-by: Samuel Ortiz <sameo@linux.intel.com>

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.
