AM3505/3517 doesn't have IO wakeup capability, so we do not need to set
the bit OMAP3430_EN_IO and the bit OMAP3430_EN_IO_CHAIN in the register
PM_WKEN_WKUP when the system enters suspend state.

Tested on AM3517EVM and OMAP3530EVM.

Omap DMA controller can prefetch data in advance in case of
destination synchronized data transfer. This may increase
performance when target HW block doesn't have fifo.
Data is waiting for transfer request in DMA fifo instead of read from memory.

The function prefix "omap2_iommu_" indicates that the prefixed
function belongs to "omap2_iommu_ops" to provide iommu basic
functionalities for the above layers. It's better to avoid the
prefixed function called in the same prefixed ones internally, like
nested here. Now "iommu_disable" is called just after fault_isr() in
the above layer. This is a little bit more sensible to keep the
consistency of module layers.

The kernel timer queue is being run currently from a GP timer running in a one
shot mode, which works in a way that when it expires, it will also stop.
Usually during this situation, the interrupt handler will ack the interrupt,
load a new value to the timer and start it again. During suspend, the
situation is slightly different, as we disable interrupts just before
timekeeping is suspended, which leaves a small window where the timer can
expire before it is stopped, and will leave the interrupt flag pending.
This pending interrupt will prevent ARM sleep entry, thus now we ack it always
when we are attempting to stop a timer.

Accessing the clkctrl register using offset of module & device is hard
to do in OMAP4 due to the way the CM1, CM2, PRM and PRCM_MPU are located
in the address space. There is no common base address anymore for all the

The easiest way to handle that on OMAP4 is to provide the absolute address
of the XXX_CLKCTRL register per hwmod.
