This became wide and scattered updates all over the sound tree as
diffstat shows: lots of (still ongoing) refactoring works in ASoC,
fixes and cleanups caught by static analysis, inclusive term
conversions as well as lots of new drivers. Below are highlights:
ASoC core:
* API cleanups and conversions to the unified mute_stream() call
* Simplify I/O helper functions
* Use helper macros to retrieve RTD from substreams
ASoC drivers:
* Lots of fixes and cleanups in Intel ASoC drivers
* Lots of new stuff: Freescale MQS and i.MX6sx, Intel KeemBay I2S,
Maxim MAX98360A and MAX98373 SoundWire, various Mediatek boards,
nVidia Tegra 186 and 210, RealTek RL6231, Samsung Midas and Aries
boards, TI J721e EVM
ALSA core:
* Minor code refacotring for SG-buffer handling
HD-audio:
* Generalization of mute-LED handling with LED classdev
* Intel silent stream support for HDMI
* Device-specific fixes: CA0132, Loongson-3
Others:
* Usual USB- and HD-audio quirks for various devices
* Fixes for echoaudio DMA position handling
* Various documents and trivial fixes for sparse warnings
* Conversion to adapt inclusive terms

static priority level knowledge from non-scheduler code.
The three APIs for non-scheduler code to set SCHED_FIFO are:
- sched_set_fifo()
- sched_set_fifo_low()
- sched_set_normal()
These are two FIFO priority levels: default (high), and a 'low' priority level,
plus sched_set_normal() to set the policy back to non-SCHED_FIFO.
Since the changes affect a lot of non-scheduler code, we kept this in a separate
tree.
When merging to the latest upstream tree there's a conflict in drivers/spi/spi.c,
which can be resolved via:
sched_set_fifo(ctlr->kworker_task);

A fairly quiet release for SPI, nothing really going on in the core
although there's been quite a bit of driver related activity. This pull
request includes the addition of some shared code in drivers/memory for
the Renesas RPC-IF which is used by a newly added SPI driver, the memory
subsystem doesn't seem to have a fixed maintainer at the minute and this
seemed like the most sensible way to get that hardware supported.
- Quite a few cleanups and optimizations for the Altera, Qualcomm GENI,
sun6i and lantiq drivers.
- Several more GPIO descriptor conversions.
- Move the Cadence QuadSPI driver from drivers/mtd to drivers/spi.
- New support for Mediatek MT8192 and Renesas RPC-IF, R8A7742 and
R8A774e1.

Before generic upgrade, both .suspend() and .resume() were invoking
pci_enable_wake(pci_dev, PCI_D3hot, 0). Hence, disabling wakeup in both
states. (Normal trend is .suspend() enables and .resume() disables the
wakeup.)
This was ambiguous and may be buggy. Instead of replicating the legacy
behavior, drop the wakeup-disable call.

Simply copying all xfers from userspace into one bounce buffer causes
alignment problems if the SPI controller uses DMA.
Ensure that all transfer data blocks within the rx and tx bounce buffers
are aligned for DMA (according to ARCH_KMALLOC_MINALIGN).
Alignment may increase the usage of the bounce buffers. In some cases,
the buffers may need to be increased using the "bufsiz" module
parameter.

Drivers using legacy PM have to manage PCI states and device's PM states
themselves. They also need to take care of configuration registers.
With improved and powerful support of generic PM, PCI Core takes care of
above mentioned, device-independent, jobs.
This driver makes use of PCI helper functions like
pci_save/restore_state(), pci_enable/disable_device(), pci_enable_wake()
and pci_set_power_state() to do required operations. In generic mode, they
are no longer needed.
Change function parameter in both .suspend() and .resume() to
"struct device*" type. Use dev_get_drvdata() to get drv data.
Compile-tested only.

This converts the PPC4xx SPI driver to use GPIO descriptors.
The driver is already just picking some GPIOs from the device
tree so the conversion is pretty straight forward. However
this driver is looking form a pure "gpios" property rather
than the standard binding "cs-gpios" so we need to add a new
exception to the gpiolib OF parser to allow this for this
driver's compatibles.

It turns out having a Rx DMA channel serviced with higher priority than
a Tx DMA channel is not enough to provide a well balanced DMA-based SPI
transfer interface. There might still be moments when the Tx DMA channel
is occasionally handled faster than the Rx DMA channel. That in its turn
will eventually cause the SPI Rx FIFO overflow if SPI bus speed is high
enough to fill the SPI Rx FIFO in before it's cleared by the Rx DMA
channel. That's why having the DMA-based SPI Tx interface too optimized
is the errors prone, so the commit 0b2b66514f ("spi: dw: Use DMA max
burst to set the request thresholds") though being perfectly normal from
the standard functionality point of view implicitly introduced the problem
described above. In order to fix that the Tx DMA activity is intentionally
slowed down by limiting the SPI Tx FIFO depth with a value twice bigger
than the Tx burst length calculated earlier by the
dw_spi_dma_maxburst_init() method.
Fixes: 0b2b66514f ("spi: dw: Use DMA max burst to set the request thresholds")

The lantiq-ssc driver uses internally an own workqueue to wait till the
data is not only written out of the FIFO but really written to the wire.
This workqueue is flushed while the SPI subsystem is working in some
other system workqueue.
The system workqueue is marked as WQ_MEM_RECLAIM, but the workqueue in
the lantiq-ssc driver does not use WQ_MEM_RECLAIM for now. Add this flag
too to prevent this warning.
This fixes the following warning:
[ 2.975956] WARNING: CPU: 1 PID: 17 at kernel/workqueue.c:2614 check_flush_dependency+0x168/0x184
[ 2.984752] workqueue: WQ_MEM_RECLAIM kblockd:blk_mq_run_work_fn is flushing !WQ_MEM_RECLAIM 1e100800.spi:0x0

Hello,
I've picked up and forward ported Martin Sperl's patches which add support for
effective_speed_hz to the SPI controllers found on all raspberry pi models.
See the following patch, which adds this feature to the SPI core, for more
information:
5d7e2b5ed5 spi: core: allow reporting the effectivly used speed_hz for a transfer
regards,
Marc
