Hi,
I would like to hear some comments about idea of scaling MMC clock
frequency. The basic idea is to lower the clock when device is
completely idle or not busy enough.
The patchset adds MMC card as a devfreq device and uses simple_ondemand
as governor. In idle this gave benefits (less energy
Lower the dw_mmc host clock from 400 MHz to 100 MHz because there are a
lot of MMC errors above 100 MHz.
Enable frequency scaling to reduce energy consumption. In idle this
reduced energy consumption by 2.6% (from 119.5 mA to 116.4 mA).

Now that all DTs have been updated, entierely drop support for
the non-DT code.
This is likely to break platforms that do not update their DT,
so print a warning at boot time.

The GIC is now always initialized from DT on tegra, and there is
no point in keeping non-DT init code.

If we detect that our DT has a LIC node, don't setup gic_arch_extn,
and skip tegra_legacy_irq_syscore_init as well.
This is only a temporary measure until that code is removed for good.

Instead of directly touching gic_arch_extn, which is about to
be removed, use gic_set_irqchip_flags instead.

Support for the TI crossbar used on the DRA7 family of chips
is implemented as an ugly hack on the side of the GIC.
Converting it to stacked domains makes it slightly more
palatable, as it results in a cleanup.
Unfortunately, as the DT bindings failed to acknowledge the
fact that this is
shmobile only uses gic_arch_extn.irq_set_wake to prevent the GIC
from returning -ENXIO when receiving a wake-up configuration request.
It is a lot simpler to tell the irq layer that we don't need any
configuration by using the IRQCHIP_SKIP_SET_WAKE, thanks to the
new gic_set_irqchip_flags

Tegra's LIC (Legacy Interrupt Controller) has been so far only
supported as a weird extension of the GIC, which is not exactly
pretty.
The stacked IRQ domain framework fits this pretty well, and allows
the LIC code to be turned into a standalone irqchip. In the process,
make the driver DT aware,
A common use of gic_arch_extn is to set up additional flags
to the GIC irqchip. It looks like a benign enough hack that
doesn't really require the users of that feature to be converted
to stacked domains.
Add a gic_set_irqchip_flags() function that platform code can
call instead of using the

Now that the users of gic_arch_extn have been fixed, drop the
feature for good. This leads to the removal of some now useless
locking.
