Note that we can now use the CONFIG_GENERIC_CPUFREQ_CPU0,
so let's only enable that. Let's use CONFIG_CPU_FREQ_DEFAULT_GOV_ONDEMAND
as suggested by Nishant.
And also let's enable thermal as explained by Nishant Menon:
Many TI SoCs using Highest frequency is not really too nice of an idea for
long periods of time. And not everything is upstream to support things
optimially - example avs class 0, 1.5 ABB consolidation with cpufreq etc..
We definitely need thermal enabled as well for device safety needs.

In sprz318f.pdf "Usage Note 2.7" says that UARTs cannot acknowledge
idle requests in smartidle mode when configured for DMA operations.
This prevents L4 from going idle. So let's use manual idle mode
instead.
Otherwise systems using Sebastian's 8250 patches with DMA will
never enter deeper idle states because of the errata above.

Commit cc824534d4 ("ARM: OMAP2+: hwmod: Rearm wake-up interrupts
for DT when MUSB is idled") fixed issues with hung UART wake-up
events by calling _reconfigure_io_chain() when MUSB is connected
or disconnected.
As pointed out by Paul Walmsley, we may need to also call
_reconfigure_io_chain() in other cases, so it should be a separate

tends to actually function only at a few discrete states. These valid

So, provide a function to easily query valid low power state that the

Based on work originally done by Jean Pihet <j-pihet@ti.com>

create a new powerdomain solution here, except fixing issues seen

Pull "ARM: OMAP2+: DRA72x/DRA74x basic support" from Tony Lindgren:
Add basic subarchitecture support for the DRA72x and DRA74x. These
are OMAP2+ derivative SoCs. This should be low-risk to existing OMAP
platforms.

ARM: DRA7: hwmod: Add dra74x and dra72x specific ocp interface lists
ARM: DRA7: Add support for soc_is_dra74x() and soc_is_dra72x() variants
Signed-off-by: Olof Johansson <olof@lixom.net>
A smattering of bug fixes for the SPI subsystem, all in driver code
which has seen active work recently and none of them with any great
global impact.
There's also a new ACPI ID for the pxa2xx driver which required no code
changes and the addition of kerneldoc for some structure fields that
were missing it and generating warnings during documentation builds as a
result.
