3d8ca8c0b9 mfd/mmc: SDHI Kconfig update
Enable the sh_mobile_sdhi mfd driver on SH-Mobile ARM
processors. While at it, make CONFIG_TMIO_MMC depend on
CONFIG_MFD_SH_MOBILE_SDHI.

f92e8f8144 mfd: Add WM831x revision B support
Revision B of the WM831x devices changes the sense of the tristate
bit for GPIO configuration, inverting it to become an enable instead.
Take account of this in the gpiolib driver.

A current sink regulation status bit has also been added in revision B,
add a flag indicating if it's present but don't use it yet.

This revision also adds an interrupt on key up for the ON pin event
which the existing code is able to take advantage of.

6d9af5af61 tmio_mmc: Use 100ms mmc_detect_change() delay
This patch changes the tmio_mmc driver to wait 100ms
before checking the card detect status. This type of
delay is quite common among mmc drivers, it seems that
most hardware platforms need to give the hardware some
time to settle before checking card availabilty.

a29aaf55cd mfd: Disable TWL4030/5030 I2C1/I2C4 internal pull-ups
This patch disables TWL4030/5030 I2C1 adn I2C4(SR) internal pull-up, to
use only the external HW resistor >=470 Ohm for the assured
functionality in HS mode.

While testing the I2C in High Speed mode, it was discovered that
without a proper pull-up resistor, there is data corruption during
multi-byte transfer. RTC(time_set) test case was used for testing.

From the analysis done, it was concluded that ideally we need a
pull-up of 1.6k Ohm(recomended) or atleast 470 Ohm or greater for
assured performance in HS mode.

6048a3dd23 mfd: Add HTCPLD driver
This change introduces a driver for the HTC PLD chip found
on some smartphones, such as the HTC Wizard and HTC Herald.
It works through the I2C bus and acts as a GPIO extender.
Specifically:

 * it can have several sub-devices, each with its own I2C
   address
 * Each sub-device provides 8 output and 8 input pins
 * The chip attaches to one GPIO to signal when any of the
   input GPIOs change -- at which point all chips must be
   scanned for changes

This driver implements the GPIOs throught the kernel's
GPIO and IRQ framework.  This allows any GPIO-servicing
drivers to operate on htcpld pins, such as the gpio-keys
and gpio-leds drivers.

53dbab7af9 mfd: Support 88pm8606 in 860x driver
88PM8606 and 88PM8607 are two discrete chips used for power management.
Hardware designer can use them together or only one of them according to
requirement.

There's some logic tightly linked between these two chips. For example, USB
charger driver needs to access both chips by I2C interface.

Now share one driver to these two devices. Only one I2C client is identified
in platform init data. If another chip is also used, user should mark it in
companion_addr field of platform init data. Then driver could create another
I2C client for the companion chip.

All I2C operations are accessed by 860x-i2c driver. In order to support both
I2C client address, the read/write API is changed in below.

reg_read(client, offset)
reg_write(client, offset, data)

The benefit is that client drivers only need one kind of read/write API. I2C
and MFD driver can be shared in both 8606 and 8607.

Since API is changed, update API in 8607 regulator driver.
