Amba core assumes the pclk to be named as apb_pclk. During device probe,
it tries to get that clock and enable that. When PM_RUNTIME is enabled,
dma clock is not explicitly enabled in pl330_probe, which causes device
probe to fail. Adding a clkdev entry for apb_pclk for mdma1 fixes the
problem.

This patch fixes following runtime error.

The bq24022 on these machines is a very simple regulator using gpios.
One provides the on/off functionality and a second one is used to
change the current between 100 and 500 mA.

This functionality can also be provided by the more generic gpio-regulator.

Therefore convert both machines which makes it possible to remove the
bq24022 driver later on.

The VPBOUNDINTST field of the ERRCONFIG register has an additional
functional meaning of force clearing the SR internal signal with VP
(sr_interruptz).
This can result in scenarios where the VP->SR protocol is violated
because the SR internal signal with VP is already high and VP will
never clear the vpirqclr signal.
Therefore during the next force update to reset to nominal voltage,
VP cannot pulse vpirqclr, so the PRCM HW cannot generate the tranxdone
IRQ and the situation is not recoverable until a cold reset is invoked.

To prevent this situation, check if status is set before clearing it
as this needs to be done only on a need basis.

SmartReflex fix for erratum ID i724.

Since OMAP's VP and PRM modules do not get reset by warm reset,
we should ensure that proper shutdown procedure is followed prior
to allowing the kernel to reboot back up.

Without this, Smartreflex module might be left active or
system might be caught in an indeterminate sequence when
software controlled reboot is triggered, leaving the next
reboot behavior to be unpredictable.

In the case of hardware controlled warm reset such as that
by watchdog timer, prevention of this scenario is not possible.
