8b40eeeadc plat-nomadik: change sleep/wakeup setting in GPIO SLPM register
This patch fixes a bug when setting SLPM register for DB8500.
When calling__nmk_gpio_set_slpm(...) offset to GPIO is now used
instead of the GPIO number itself.

01727e61f0 plat-nomadik: implement safe switch sequence for Alt-C
Setting pinmux alternative C for a GPIO pin is actually not
so easy since it ivolves setting value "1" in two registers,
and since the combined result will take effect for intermediate
values (01 or 10) this will cause glitches while you wrote one
register but have not yet written the other.

This patch implements a series of kludges including an optional
machine-specific callback to avoid glitches when changing pin
mux mode to alternative C.

9c66ee6f55 plat-nomadik: pull-up/down settings for GPIO resume
Suspend/resume didn't take care of pull-up and pull-down

change pull up/down settings, depending on pin input value.
Output values are now also restored.

33b744b351 plat-nomadik: support secondary GPIO interrupts
When GPIOs wake up the system from sleep mode, the normal GPIO interrupt
handler does not hit and the normal interrupt status register does not
contain the status. Instead the secondary GPIO handler does, and the
interrupt status needs to be retrieved from the wakeup status saved by
the suspend/resume code.

f91f9cd505 arm: tcc8k: Fix bus clock calculation
There are two dividers used to derive bus clock from system clock:
system clock is divided by SCKDIV+1, then by BCKDIV+1. SCKDIV divider
has been ignored up to now, which is no problem as long as it is 0.

Take SCKDIV into account for bus clock calculation.

fe03a9f7bb arm: tcc8k: Fix clock rate calculation
The calculation of the best divider value for a requested clock rate
always returned a value that was slightly too large. It was also not
protected against possible divisions by zero.

Request for very low, but non zero rates would cause the ACLK divisor
field to overflow. Catch this situation by using the maximum value.

The internal function aclk_set_rate() calculates the correct divider
value, but doesn't write it back to the register. Add the write back.
