872c1b14e7 mfd: Section cleanup of 88pm860x driver
This patch fixes three section mismatches.

WARNING: drivers/mfd/88pm860x.o(.text+0x12): Section mismatch in
reference from the function pm860x_device_exit() to the function
.devexit.text:device_irq_exit()
The function pm860x_device_exit() references a function in an exit
section.
Often the function device_irq_exit() has valid usage outside the exit
section
and the fix is to remove the __devexit annotation of device_irq_exit.

WARNING: drivers/mfd/88pm860x.o(.text+0xb0): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8606_init()
The function pm860x_device_init() references
the function __devinit device_8606_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8606_init is wrong.

WARNING: drivers/mfd/88pm860x.o(.text+0xbe): Section mismatch in
reference from the function pm860x_device_init() to the function
.devinit.text:device_8607_init()
The function pm860x_device_init() references
the function __devinit device_8607_init().
This is often because pm860x_device_init lacks a __devinit
annotation or the annotation of device_8607_init is wrong.

9f79e9db2e regulator: use voltage number array in 88pm860x
A lot of condition comparision statements are used in original driver. These
statements are used to check the boundary of voltage numbers since voltage
number isn't linear.

Now use array of voltage numbers instead. Clean code with simpler way.

2afa62ea76 mfd: Use genirq in 88pm860x
Use genirq to simplify IRQ handling in 88pm860x. Remove the interface of
mask/free IRQs on 88pm860x. All these work is taken by genirq. Update the
touchscreen driver of 88pm860x since IRQ handling is changed.

5c42e8c4a9 mfd: Add irq support in 88pm860x
88PM860x is a complex PMIC device. It contains touch, charger, sound, rtc,
backlight, led, and so on.

Host communicates to 88PM860x by I2C bus. Use thread irq to support this
usage case.

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.
