The soc_compr_copy callback is currently broken. Since the
changes to move the compr_ops over to the component the return
value is not correctly propagated, always returning zero on
success rather than the number of bytes copied. This causes
user-space to stall continuously reading as it does not believe
it has received any data.
Furthermore, the changes to move the compr_ops over to the
component iterate through the list of components and will call
the copy callback for any that have compressed ops. There isn't
currently any consensus on the mechanism to combine the results
of multiple copy callbacks.
To fix this issue for now halt searching the component list when
we locate a copy callback and return the result of that single
callback. Additional work should probably be done to look at the
other ops, tidy things up, and work out if we want to support
multiple components on a single compressed, but this is the only
fix required to get things working again.

For certain platforms, it is required to start the clocks (mclk/sclk/fs)
before the stream start. Example: for few chrome systems, codec needs the
mclk/sclk to be enabled early for a successful clock synchronization and
for few IVI platforms, clock need to be enabled at boot and should be ON
always.
Add the required structures and create set_dma_control ipc to enable or
disable the clock. To enable sclk without fs, mclk ipc structure is used,
else sclkfs ipc structure is used.
Clock prepare/unprepare are used to enable/disable the clock as the IPC
will be sent in non-atomic context. The clk set_dma_control IPC
structures are populated during the set_rate callback and IPC is sent
to enable the clock during prepare callback.
This patch creates virtual clock driver, which allows the machine driver
to use the clock interface to send IPCs to DSP to enable/disable the
clocks.

Commit 3bb0f7c31b ("ASoC: don't use snd_soc_write/read on twl4030")
caused regressions for both twl4030 and twl6040 as it assumes the
ASoC driver is using regmap. As a side effect, this also causes a
considerable increase in idle power consumption omap3 boards using
twl4030 as the PMIC.
This is because the removal of read and write function pointers
causes some of the ASoC IO functions to not do anything. For example,
snd_soc_register_card() calls snd_soc_dapm_new_widgets() that calls
snd_soc_codec_drv_read() that now does nothing.
A long term solution suggested by Mark Brown <broonie@kernel.org>
is to make the twl drivers use regmap by adding a call to
snd_soc_codec_set_regmap(). This however needs more consideration
as currently the driver internal reads do caching and we would have
both regmap access and internal read/write access accessing the same
hardware registers.
So to fix the regression, let's just do a partial revert adding back
the read and write function pointers. Note that other non-regmap
ASoC drivers may need similar patches.

Power Down Release Command (PMVR, PMDAC, RSTN, PMDA1-PMDA6)
which are located on PW_MGMT1 / PW_MGMT3 register must be
write again after at least 5 LRCK cycle or later on each command.
Otherwise, Playback volume will be 0dB.
Basically, it should be

1.x Dummy write to Power Management1
2. PowerDownRelease by Power Management3 <= call 2.x after 5LRCK

To avoid too many dummy write, this patch is merging these.

The conversion of the alpha architecture PCI host bridge legacy IRQ
mapping/swizzling to the new PCI host bridge map/swizzle hooks carried
out through:
commit 0e4c2eeb75 ("alpha/PCI: Replace pci_fixup_irqs() call with
host bridge IRQ mapping hooks")
implies that IRQ for devices are now allocated through pci_assign_irq()
function in pci_device_probe() that is called when a driver matching a
device is found in order to probe the device through the device driver.
Alpha noname platforms required IRQ level programming to be executed
in sio_fixup_irq_levels(), that is called in noname_init_pci(), a
platform hook called within a subsys_initcall.
In noname_init_pci(), present IRQs are detected through
sio_collect_irq_levels() that check the struct pci_dev->irq number
to detect if an IRQ has been allocated for the device.
By the time sio_collect_irq_levels() is called, some devices may still
have not a matching driver loaded to match them (eg loadable module)
therefore their IRQ allocation is still pending - which means that
sio_collect_irq_levels() does not programme the correct IRQ level for
those devices, causing their IRQ handling to be broken when the device
driver is actually loaded and the device is probed.
Fix the issue by adding code in the noname map_irq() function
(noname_map_irq()) that, whilst mapping/swizzling the IRQ line, it also
ensures that the correct IRQ level programming is executed at platform
level, fixing the issue.

workqueue: avoid hard lockups in show_workqueue_state()
We have various small DT fixes, and one important regression fix:
The recent device tree bugfixes that were intended to address issues that
'dtc' started warning about in 4.15 fixed various USB PHY device nodes,
but it turns out that we had code that depended on those nodes being
incorrect and the probe failing with a particular error code. With the
workaround we can also deal with correct device nodes.
The DT fixes include:
- Allwinner A10 and A20 had the display pipeline set up incorrectly
(introduced in v4.15)
- The Altera PMU lacked an interrupt-parent (never worked)
- Pin muxing on the Openblocks A7 (never worked)
- Clocks might get set up wrong on Armada 7K/8K (4.15 regression)
We now have additional device tree patches to address all the remaining
warnings introduced in 4.15, but decided to queue them for 4.16 instead,
to avoid risking another regression like the USB PHY thing mentioned
above.

More than we'd like after rc8, but nothing very alarming either, just tying up
loose ends before the release:
Since we changed powernv to use cpufreq_get() from show_cpuinfo(), we see
warnings with PREEMPT enabled. But the preempt_disable() in show_cpuinfo()
doesn't actually prevent CPU hotplug as it suggests, so remove it.
Two updates to the recently merged RFI flush code. Wire up the generic sysfs
file to report the status, and add a debugfs file to allow enabling/disabling it
at runtime.
Two updates to xmon, one to add the RFI flush related fields to the paca dump,
and another to not use hashed pointers in the paca dump.
And one minor fix to add a missing include of linux/types.h in asm/hvcall.h, not
seen to break the build in upstream, but correct anyway.
