Alan Cox says <quote>the irq disable/enable is in the register

restore_flags in a different function you mess up all the

So never pass the flags word set by
<function>spin_lock_irqsave()</function> and brethren to another
function (unless it's declared <type>inline</type>). Usually no-one
does this, but now you've been warned. Dave Miller can never do
anything in a straightforward manner (I can say that, because I have
pictures of him and a certain PowerPC maintainer in a compromising
position).

/* Set up the 405LP clock and power management unit for aggressive power
management.
Briefly, there are 3 CPM "classes":
Class 1 - Either completely asleep or awake. The "force" state is
equivalent to the "enabled" state. Many Class 1 units are
critical system components and are never power managed.
Class 2 - Can be enabled for power management, where sleep requests are
made by the peripheral, typically after an inactivity timeout.
When sleeping, critical interfaces remain active, and
awaken the unit whenever it is targeted with a transaction.
Class 3 - Can be enabled for power management, where sleep requests are
made by the CPM. Power management for these units typically
will require intelligence in a device driver.
In the current implementation, the "force" bits are only used on Class 1
devices, and only when the associated driver has the intelligence necessary
to "unforce" the power management state. A previous scheme, which tried to
enable power management based on whether a particular driver was compiled
with the kernel, caused many problems and is never used here.
Class 2 devices with timeouts are normally initialized for the most
aggressive values. There is no power management benefit of "forcing" Class
2 devices over letting their inactivity timeouts take effect. Therefore,
after being set up here, Class 2 device drivers don't need to worry about
CPM.

tell the system the Pixel clock frequency it needs, regardless of whether
run-time frequency scaling is configured. A hook and a couple of global
variables are always present and will be used by the RTVFS driver if it is
loaded.
Pixel clock setting is kind of a hack, as the frequency steps available from
the PLB/PixClk divider may be too large to guarantee that we'll hit within
the given limits. We never set the frequency above the upper bound, but due
to quantization may need to set the frequency below the lower bound. So far
it works OK for the panels we've tried.
In general, the choice of a system clock frequency should be made with
consideration of the LCD panel to be attached, to guarantee a good clock
divider for the Pixel clock regardless of frequency scaling.
Clock frequencies are in KHz. If pixclk_min or pixclk_max are zero, we set
the lowest possible frequency to conserve energy. */
