Hi Victor, Taras,

All OMAP IP blocks expect LE data, but CPU may operate in BE mode.
Need to use endian neutral functions to read/write h/w registers.
I.e instead of __raw_read[lw] and __raw_write[lw] functions code
need to use

This patch makes the edma driver resume correctly after suspend. Tested
on an AM33xx platform with cyclic audio streams and omap_hsmmc.
All information can be reconstructed by already known runtime

As we now use some functions that were previously only used from __init

This a resend:
- no spin_lock during register access in pm_runtime suspend/resume
- reworked GPIO enable / disable logic, also suspend/resume

mmc:
The am335x can't detect pending cirq in PM runtime suspend.
This patch reconfigures dat1 as a GPIO before going to suspend.
SDIO interrupts are detected with the GPIO, the GPIO will only wake
the module from suspend, SDIO irq detection will still happen through the
IP block.
Idea of remuxing the
For now, only support SDIO interrupt if we are booted with
DT. This is because some platforms need special quirks. And
we don't want to add new legacy mux platform init code
callbacks any longer as we are moving to DT based booting
anyways.
Broken hardware, missing the swakueup line, should
Add SDIO IRQ entries to debugfs entry. Note that PSTATE shows current
