As established for the MMCI, it is proper to map the DMA buffers
on the DMA engine which is the one actually performing the DMA.

We need to run the card detect tasklet at the end of slot initialisation
as it is possible that a card has been inserted prior to boot, so we don't
see an insertion interrupt and now the card is sitting there inserted but
with no power to it.

The test area size was set to the preferred erase size but for comparison
purposes it is better if it is the same size for different devices. Make
it a multiple of preferred erase size that is greater than or equal to 4MiB.

This sdio card supports having its sdio clock shutdown.
It is also not using the SDIO IRQ, but rather uses a side gpio irq.

Some sdio card are not following sdio standard, and do not work
when the sdio bus's clock is gated.
To keep functionnality for all legacy driver, we turn this quirk on
for every sdio card.
Drivers needs to disable the quirk manually when someone verifies that
their supported card works with clock gating.

Some cards have quirks valid for every platforms using current
platform quirk hooks leads to a lot of code and debug duplication.
So we inspire a bit from what exists in PCI subsystem and do our own
per vendorid/deviceid quirk. We still drop the complexity of the pci
quirk system (with special section tables, and so on).
That can be added later if needed.

While the MMC handled the card's read only flag correctly on open,
it did not setup the flag in the allocated disk structure. The
consequence being that probing the /sys/class/block/mmcblkX/ro
attribute always reported 0.

Enhanced area feature is a new feature defined in eMMC4.4 standard. This
user data area provides higher performance/reliability, at the expense
of using twice the effective media space due to the area using SLC.
The MMC driver now reads out the enhanced area offset and size and adds
them to the device attributes in sysfs. Enabling the enhanced area can
only be done once, and should be done in manufacturing. To use this
feature, bit ERASE_GRP_DEF should also be set.
Documentation/ABI/testing/sysfs-devices-mmc describes the two new
attributes.

The code path entered via mmc_host_enable() can include register
accesses to the HSMMC IP block. For this to work, both the device
interface clock and functional clock need to be enabled before
mmc_host_enable() is called. However, omap_hsmmc_probe() calls
mmc_host_enable() before enabling the device interface clock.
Fix by calling mmc_host_enable() after the device interface clock is
enabled.

OMAP2420 platform consists of mmc block as in omap1 and not the
hsmmc block as present in omap2430, omap3, omap4 platforms.
Removing all base address macro defines except keeping one for OMAP2420 and
adapting only hsmmc device registration and driver to hwmod framework.
Changes involves:
1) Remove controller reset in devices.c which is taken care of
by hwmod framework.
2) Using omap-device layer to register device and utilizing data from
hwmod data file for base address, dma channel number, Irq_number,
device attribute.
3) Update the driver to use dev_attr to find whether controller
supports dual volt cards

Based on a patch from Linus Walleij.
Add dmaengine based support for DMA to the MMCI driver, using the
Primecell DMA engine interface. The changes over Linus' driver are:
- rename txsize_threshold to dmasize_threshold, as this reflects the
purpose more.
- use 'mmci_dma_' as the function prefix rather than 'dma_mmci_'.
- clean up requesting of dma channels.
- don't release a single channel twice when it's shared between tx and rx.
- get rid of 'dma_enable' bool - instead check whether the channel is NULL.
- detect incomplete DMA at the end of a transfer. Some DMA controllers
(eg, PL08x) are unable to be configured for scatter DMA and also listen
to all four DMA request signals [BREQ,SREQ,LBREQ,LSREQ] from the MMCI.
They can do one or other but not both. As MMCI uses LBREQ/LSREQ for the
final burst/words, PL08x does not transfer the last few words.
- map and unmap DMA buffers using the DMA engine struct device, not the
MMCI struct device - the DMA engine is doing the DMA transfer, not us.
- avoid double-unmapping of the DMA buffers on MMCI data errors.
- don't check for negative values from the dmaengine tx submission
function - Dan says this must never fail.
- use new dmaengine helper functions rather than using the ugly function
pointers directly.
- allow DMA code to be fully optimized away using dma_inprogress() which
is defined to constant 0 if DMA engine support is disabled.
- request maximum segment size from the DMA engine struct device and
set this appropriately.
- removed checking of buffer alignment - the DMA engine should deal with
its own restrictions on buffer alignment, not the individual DMA engine
users.
- removed setting DMAREQCTL - this confuses some DMA controllers as it
causes LBREQ to be asserted for the last seven transfers, rather than
six SREQ and one LSREQ.
- removed burst setting - the DMA controller should not burst past the
transfer size required to complete the DMA operation.

We don't need to store the number of bytes transferred in our host

We don't need to switch to data available interrupts if there's at
least half a FIFO depth worth of data remaining, as we'll still get
the FIFO half full interrupt. Keep this interrupt masked off until
we have less than half the FIFO depth worth of data remaining.

The data counter counts the number of bytes transferred on the MMC bus.
When a FIFO overrun occurs, we will not have transferred a FIFOs-worth
of data to memory, and so the data counter will be a FIFOs-worth ahead.
If this occurs on a block boundary, we will report one too many sectors
as successful. Fix this.

We don't actually need this and it causes problems for internal use of
this functionality. Currently there is a single use of the FILE * pointer.
That is the serial core which uses it to check tty_hung_up_p. However if
that is true then IO_ERROR is also already set so the check may be removed.
