Provide an explicit match string for PXA3xx SSP ports.
Without this match string, SSP0/SSP1/SSP2 in PXA3xxx will be consided as
PXA27x SSP Port.

James Drew reports another bug whereby the NFS client is now sending
an OPEN_DOWNGRADE in a situation where it should really have sent a
CLOSE: the client is opening the file for O_RDWR, but then trying to
do a downgrade to O_RDONLY, which is not allowed by the NFSv4 spec.

There is a race between nfs4_state_manager() and
nfs_server_remove_lists() that happens during a nfsv3 mount.
The v3 mount notices there is already a supper block so
nfs_server_remove_lists() called which uses the nfs_client_lock
spin lock to synchronize access to the client list.
At the same time nfs4_state_manager() is running through
the client list looking for work to do, using the same
lock. When nfs4_state_manager() wins the race to the
list, a v3 client pointer is found and not ignored
properly which causes the panic.
Moving some protocol checks before the state checking
avoids the panic.

DRA74x and DRA72x family of processors vary slightly in the number
of CPUs. So, add different instances of PMU for each of these processor
groups. Further, since the interrupts bypass crossbar and are directly
connected to GIC, mark the dts nodes with relevant information.

In order to handle errata I688, a page of sram was reserved by doing a
static iotable map. Now that we use gen_pool to manage sram, we can
completely remove all of these static mappings and use gen_pool_alloc()
to get the one page of sram space needed to implement errata I688.
omap_bus_sync will be NOP until SRAM initialization happens.

Use drivers/misc/sram.c driver to manage SRAM on all DT only
OMAP platforms (am33xx, am43xx, omap4 and omap5) instead of
the existing private plat-omap/sram.c
Address and size related data is removed from mach-omap2/sram.c
and now passed to drivers/misc/sram.c from DT.
Users can hence use general purpose allocator apis instead of
OMAP private ones to manage and use SRAM.

cgroup_pidlist_start() holds cgrp->pidlist_mutex and then calls
pidlist_array_load(), and cgroup_pidlist_stop() releases the mutex.
It is wrong that we release the mutex in the failure path in
pidlist_array_load(), because cgroup_pidlist_stop() will be called
no matter if cgroup_pidlist_start() returns errno or not.

With the IO chain reconfigure fixed, we can now enable the PMIC

As we have support for this in board-rx51-peripherals.c, let's
add it to the .dts files too.
Note that the reset GPIO will eventually go to the driver.
For now let's just pull it down and skip any further reset
in case the bootloader has configured the MAC address so
NFSroot works.
Also note that after 3430-sdp are using proper GPMC timings
we can remove the tests for smsc,lan91c94 in gpmc.c.

This is no longer needed as the device specific wake-up event
can now be specified with interrupts-extended property where
the second interrupt is the pinctrl-single register, such as
the UART3 RX pin.
Note that twl4030_omap3.dtsi needs to set WAKEUPENABLE for
off-idle to properly trigger the PMIC scripts. And GPIO pins
still need to set WAKEUPENABLE for wake-up events.

Compared to legacy booting, we don't have wake-up events enabled
for device tree based booting. This means that if deeper idle
states are enabled, the device won't wake up to UART events and
seems like it has hung.
Let's fix that by adding the wake-up interrupt. Note that we
don't need to set the PIN_OFF_WAKEUPENABLE any longer, that's
handled by the wake-up interrupt when the serial driver does
request_irq on it.
Tested with the following on omap3-overo-summit that has the
ES2.1 omap:
#!/bin/bash
uarts=$(find /sys/class/tty/ttyO*/device/power/ -type d)
for uart in $uarts; do
echo 3000 > $uart/autosuspend_delay_ms
done
uarts=$(find /sys/class/tty/ttyO*/power/ -type d)
for uart in $uarts; do
echo enabled > $uart/wakeup

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 cc824534d4fe ("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
flag. Let's add HWMOD_RECONFIG_IO_CHAIN as suggested by Paul.

We can only determine the final security level when both pairing request
and response have been exchanged. When initiating pairing the starting
target security level is set to MEDIUM unless explicitly specified to be
HIGH, so that we can still perform pairing even if the remote doesn't
have MITM capabilities. However, once we've received the pairing
response we should re-consult the remote and local IO capabilities and
upgrade the target security level if necessary.
Without this patch the resulting Long Term Key will occasionally be
reported to be unauthenticated when it in reality is an authenticated
one.
