Port open call for smux is blocking. There is a 5 seconds default
timeout for the open call. The total number of retries for opening
the port makes the total wait time to be 11 minutes. This timeout
becomes an issue if QSC does not come up in time. Adding a device
attribute lets the user space control/reduce the timeout value.

The MPM drivers keeps account of all enabled interrupts in the system to
be able to configure the MPM hardware during low power sleep modes. To
ensure that MPM receives notification for all interrupts, it needs to be

The APIs are currently unused. They were added for the benefit of
the acpuclock-8960 driver, which needed them to ensure that CPUs
were really power-collapsed before their clocks were disabled.
The current acpuclock-krait driver solves this problem a different
way, by taking advantage of hardware features that were not
available in early (unreleased) versions of the Krait cores. Now,
instead of disabling the CPUs' clocks, a low-frequency always-on
clock source is selected and hardware clock gating is employed to
save power. With this, it is no longer necessary to wait for the
SPM to confirm the CPU has power-collapsed before acpuclock's
CPU_DEAD callback executed.

8064v1.x hardware has a known issue where the CPU's primary and secondary
clock source muxes reset to their default states when the L2 cache is
power-collapsed. To work around this, software sets these muxes to their
default positions (QSB selected) before L2 power-collapse so that software
state remains in sync with the hardware.
Replace this workaround with an improved one that incurs less of a latency
penalty in the hotplug path (since selecting the slow QSB source may slow
down hotplug). The improved workaround targets the root of the problem,
which is that the L2CPUVRF8 CP15 register becomes corrupt when L2CPMR or
L2CPUCPMR are written to. It is this corruption that results in the
change in L2 power-collapse behaviour and the muxes getting reset.
Implement the improved workaround, which saves and restores L2CPUVRF8's
value around L2CPMR and L2CPUCPMR writes. Although the register is still
corrupt for a short period of time before the register is restored, this
is of no consequence since L2 power-collapse cannot happen at that time.
