As sysfs_notify_dirent has been made irq safe, there is no reason to not
call it directly from irq. With the work_struct removed, the remaining
element in poll_desc is a sysfs_dirent pointer which may not be NULL. We
can therefore store it directly in the idr and pass it as context to the
irq handler.
Most part of the patch deals with renaming defines and variables to
reflect their new use without functional change.
I also took the opportunity to initialize the idr statically.

The gpios on the max730x chips have support for internal pullups while in
input mode.
This patch adds support for configuring these pullups via platform data.
A new member ("input_pullup_active") to the platform data struct is
introduced. A set bit in this variable activates the pullups while the
respective port is in input mode. This is a compatible enhancement since
unset bits lead to disables pullups which was the default in the original
driver.
_Note_: the 4 lowest bits in "input_pullup_active" are unused because the
first 4 ports of the controller are not used, too.

On some Samsung SoCs not all SDHCI controllers have card detect (CD) line.
For some embedded designs it is not even needed, because ususally the
device (like SDIO flash memory or wifi controller) is permanently wired to
the controller. There are also systems which have a card detect line
connected to some of the external interrupt lines or the presence of the
card depends on some other actions (like enabling a power regulator).
This patch adds support for all these cases. The following card detection
methods are possible:
1. internal sdhci host card detect line
2. external event
3. external gpio interrupt
4. no card detect line, controller will poll for the card
5. no card detect line, card is permanently wired to the controller
(once detected host won't poll it any more)
By default, all existing code would use method #1, what is compatible with
the previous version of the driver.
In case of external event, two callbacks must be provided in platdata:
ext_cd_init and ext_cd_cleanup. Both of them get a callback to a function
that notifies the s3c-sdhci host contoller as their argument. That
callback function should be called from the even dispatcher to let host
notice the card insertion/removal.
In case of external gpio interrupt, a gpio pin number must be provided in
platdata (ext_cd_gpio parameter), as well as the information about the
polarity of that gpio pin (ext_cd_gpio_invert). By default
(ext_cd_gpio_invert == 0) gpio value 0 means 'card has been removed', but
this can be changed to 'card has been removed' when ext_cd_gpio_invert ==
1.
This patch adds all required changes to sdhci-s3c driver.

By default host bus clock is used, what causes some problems on machines
with 133MHz bus, because the SDHCI divider cannot be as high get proper
clock value for identification mode. This is not a problem for the
controller, because it can generate lower frequencies from other clock
sources. This patch changes sdhci driver to use get_min_clock() call if
it has been provided.

There are some chips (like TI WL12xx series) that can be interfaced over
SDIO but don't support the SDIO specification, meaning that they are
missing CIA (Common I/O Area) with all it's registers. Current Linux SDIO
implementation relies on those registers to identify and configure the
card, so non-standard cards can not function and cause lots of warnings
from the core when it reads invalid data from non-existent registers.
After this patch, init_card() host callback can now set new quirk
MMC_QUIRK_NONSTD_SDIO, which means that SDIO core should not try to access
any standard SDIO registers and rely on init_card() to fill all SDIO
structures instead. As those cards are usually embedded chips, all the
required information can be obtained from machine board files by the host
driver when it's called through init_card() callback.
