The i2c-exynos5.c driver can be reused for the HSI2C controller
on Exynos7 SoCs from Samsung.
This patch adds the Kconfig dependency to choose i2c-exynos5.c
for CONFIG_ARCH_EXYNOS7.

. Introduce a variant struct to support the changes in H/W
3. Reset the module during init. Thus, bringing the module back
to default state irrespective of what firmware did with it.

From: Naveen Krishna Ch
Using pdev->dev with device_for_each_child() would iterate over all
of the children of the platform device and delete them.
Thus, causing crashes during module unload.
We should be using the indio_dev->dev structure for
registering/unregistering child nodes.
Do a soft reset software if a timeout happens.
This is applicable only for ADC_V2.

drivers/iio/adc/exynos_adc.c | 50
ADC module on Exynos5 SoCs runs at 600KSPS. At this conversion rate,
waiting for 1000 msecs is wasteful (incase of h/w failure).
Hence, reduce the time out to 100msecs and use
wait_for_completion_timeout() instead of
wait_for_completion_interruptible_timeout()

This patch maintains the following order in
probe(), remove(), resume() and suspend() calls
regulator enable, clk prepare enable
...
clk disable unprepare, regulator disable
While at it,
1. enable the regulator before the iio_device_register()
2. handle the return
Add reinit_completion() before the wait_for_completion_timeout in
raw_read() call.
