The "nop" driver isn't a do-nothing-stub but supports a couple functions
like clock on/off or is able to use a voltage regulator. This patch
simply renames the driver to "generic" since it is easy possible to
extend it by a simple function istead of writing a complete driver.

With the recent cleanup in Exynos platform code notably commits
17859bec ("ARM: EXYNOS: Do not select legacy Kconfig symbols any
more") and b9222210 ("ARM: EXYNOS: Remove mach/gpio.h"), the definition
of ARCH_NR_GPIOS got removed. This started causing problems on SoCs like
Exynos4412 which have more than the default number of GPIOs. Thus define
this number in KConfig file which takes care of current SoC requirements
and provides scope for GPIO expanders. Without this patch we get the
following errors during boot:

This patch restores serial port operation which has been broken since
commit 60e93575 ("serial: samsung: enable clock before clearing
pending interrupts during init")

That commit only uncovered the real issue which was missing clkdev
entries for the "uart" clocks on S3C2440. It went unnoticed so far
because return value of clk API calls were not being checked at all
in the samsung serial port driver.

This patch should be backported to at least 3.10 stable kernel, since
the serial port has not been working on s3c2440 since 3.10-rc5.

The fec/enet driver calculates MDC rate with the formula below.

  ref_freq / ((MII_SPEED + 1) x 2)

The ref_freq here is the fec internal module clock, which is missing
from clk-vf610 clock driver right now.  And clk-vf610 driver mistakenly
supplies RMII clock (50 MHz) as the source to fec.  This results in the
situation that fec driver gets ref_freq as 50 MHz, while physically it
runs at 66 MHz (fec module clock physically sources from ipg which runs
at 66 MHz).  That's why software expects MDC runs at 2.5 MHz, while the
measurement tells it runs at 3.3 MHz.  And this causes the PHY KSZ8041
keeps swithing between Full and Half mode as below.
