Holger Schurig 1b3c9bf2cd imx21: activate i2c
Set the correct clkdev-name for the i2c clock.

It also get's rid of the ARCH_NR_GPIOS define on the rationale
that isn't an ARCH-wide setting anyway. If a device has two
pca953x devices, the reserved number will be wrong.

Russell King be093beb60 [ARM] pass reboot command line to arch_reset()
OMAP wishes to pass state to the boot loader upon reboot in order to
instruct it whether to wait for USB-based reflashing or not.  There is
already a facility to do this via the reboot() syscall, except we ignore
the string passed to machine_restart().

This patch fixes things to pass this string to arch_reset().  This means
that we keep the reboot mode limited to telling the kernel _how_ to
perform the reboot which should be independent of what we request the
boot loader to do.

Sascha Hauer a2865197a5 [ARM] MXC: Use a single function for decoding a PLL
We had 3 versions of this function in clock support for MX1/2/3
Use a single one instead. I picked the one from the MX3 as it seems
to calculate more accurate as the other ones. Also, on MX27 and MX31 mfn
can be negative, this hasn't been handled correctly on MX27 since now.

This patch has been tested on MX27 and MX31 and produces the same clock
frequencies for me.

Internal clock path handling for the i.MX27 CPU.

Changed against the original Freescale code (and against clocklib for example):
 - clock rate is always calculated whenever one ask for the current rate.
   (means no "rate" member in the clock structure).
   So switching the PLL base frequency will propagate immediately to all
   other clocks that are depending on this frequency.
