Realtek card reader supports both SD and MS card. According to the
settings of rtsx MFD driver, SD host will be probed before MS host.
If we boot/reboot Linux with SD card inserted, the resetting flow of SD
card will succeed, and the following resetting flow of MS is sure to fail.
Then MS upper-level driver will ask rtsx driver to turn power off. This
request leads to the result that the following SD commands fail and SD card
can't be accessed again.
In this commit, Realtek's SD and MS host driver will check whether the card
that upper driver requesting is the one existing in the slot. If not, Realtek's
host driver will refuse the operation to make sure the exlusive accessing
at the same time.

When compiling the AB8500 core driver in the latest
MFD tree the following happens:
CC drivers/mfd/ab8500-debugfs.o
/home/elinwal/linux-next/drivers/mfd/ab8500-debugfs.c:157:3: error: 'AB8500_SYS_CTRL1_BLOCK' undeclared here (not in a function)

/home/elinwal/linux-next/drivers/mfd/ab8500-debugfs.c:157:2: error: (near initialization for 'debug_ranges')
(...)
This is due to a missing include statement, so fix
it up.

A lot of mfd drivers select MFD_CORE which however depends on
GENERIC_HARDIRQS support.
So add the missing dependency to all drivers to get rid of
this link error:
ERROR: "irq_create_mapping" [drivers/mfd/mfd-core.ko] undefined!

Add irqdomains for max8925's main irq, wrap irq register operations
into irqdomain's map func. it is necessary for dt support.
Also, add dt support for max8925 driver.

The vexpress_sysreg_init() is a core_initcall() already and it can
trigger the early initialisation if a matching node is found. This patch
allows the SoC code to avoid calling vexpress_sysreg_of_early_init()
explicitly.

Implement different ways of selecting driving capability(a necessary adjustment
along with voltage change). It was origionally in device-independent
mmc/host/rtsx_pci_sdmmc.c. Moving it here to support devices which may have a
different way of adjustment.

1. Schedule card detect work at the end of the ISR
2. Callback function ops->cd_deglitch may delay for a period of time.
It is not proper to call this callback when local irq disabled.
3. Card detect flow can't be executed in parallel with other card reader
operations, so it's better to be protected by mutex.

In function rtsx_pci_switch_clock, some variables, such as min_n, max_n,
and max_div, are not necessary. And those assigned values look very
obscure for others. It's more proper to use macro definitions here to
replace these variables.

The tps65090 mfd driver implement the suspend/resume callbacks
which just disable and enable irqs in suspend/resume respectively.
This operation is already done in irq suspend and irq_resume and
hence it is not require to implement the same in the driver.
Remove this non-require code.

When device is get added through DT then irq_base is 0 (zero)
and in this case regmap_irq_chip_get_base() generates warning.
The interrupt of this device get added through irq_domain_add_linear()
when irq_base is 0.
Hence pass the irq domain in place of base_irq when calling
mfd_add_devices().
