The commit 30f3a6ab44d8 ("spi: pxa2xx: Add support for both chip selects on
Intel Braswell") introduces a support of chipselects for Intel Braswell SPI
host controller. Though it missed to convert the PCI part of the driver.
Do conversion here which enables both chipselects on Intel Braswell when
enumerated via PCI.
We don't care about num_chipselect value since it is overrided inside core
driver.

When the clock is coming from the cmu it is not required to be
disabled and then re-enabled in order to change the rate.
Besides, some exynos chipsets (e.g. exynos5433) do not deliver
any to the SFR if one from the pclk ("spi" in this case) or sclk
("busclk") is disabled.
Remove the clock disabling/enabling to avoid falling into this
situation.

OMAP35x and OMAP37x mentions in the McSPI End-of-Transfer Sequences section
that if the McSPI is configured as a Master and only DMA RX is being
performed then the DMA transfer size needs to be reduced by 1 or 2.
This was originally implemented by:
commit 57c5c28dbc83 ("spi: omap2_mcspi rxdma bugfix")
This patch adds comments to clarify what is going on in the code since its
not obvious what problem its addressing.

Some IoT and maker software stacks are using spidev to perform raw access
to the SPI bus instead of relying existing drivers provided by the kernel.
They then implement their own "drivers" in userspace on top of the spidev
raw interface. This is far from being an ideal solution but we do not want
to prevent using mainline Linux in these devices.
Now, it turns out that Windows has similar SPI devices than spidev which
allow raw access on the SPI bus to userspace programs as described in the
link below:
https://msdn.microsoft.com/windows/hardware/drivers/spb/spi-tests-in-mitt
These SPI test devices are also meant to be used during development and
testing.
In order to allow usage of spidev for development and testing in Linux, add
those same ACPI IDs to the spidev driver (which is Linux counterpart of the
Windows SPI test devices), but complain loudly so that users know it is not
good idea to use it in production systems. Instead they should be using
proper drivers for peripherals connected to the SPI bus.

The workqueue "workqueue" serves as a driver message queue.
It has a single work item(&drv_data->pump_messages) and hence doesn't
require ordering. Also, it is not being used on a memory reclaim path.
Hence, the singlethreaded workqueue has been replaced with the use of
system_wq.
System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.
Work item has been flushed in bfin_sport_spi_destroy_queue() to ensure
that there are no pending tasks while disconnecting the driver.

The speed limits are unset in the sun4i and sun6i SPI drivers.
The maximum speed of SPI master is used when maximum speed of SPI slave
is not specified. Also the __spi_validate function should check that
transfer speeds do not exceed the master limits.
The user manual for A10 and A31 specifies maximum
speed of the SPI clock as 100MHz and minimum as 3kHz.
Setting the SPI clock to out-of-spec values can lock up the SoC.

Currently, even if the PXA2xx SPI master supports DMA, it won't be
enabled unless (i) the slave device is enumerated through ACPI, or
(ii) the slave device is registered with board-specific
controller_data specified. Even then, there isn't a field in the
controller_data that explicitly enables dma - it just gets enabled
if the master supports it and controller_data is non-NULL.
This means that drivers which register SPI devices on a bus without
awareness of this controller cannot avail of DMA performance gains.
This patch allows DMA transfers to be used if supported.

window (linked to one SPI chip-select on one of the SPI controllers)
will be transferred directly to the SPI bus. Without the need to control
the SPI registers in between. This can improve the SPI transfer rate in
such cases.
Both, direct-read and -write mode are supported. But only the write
mode has been tested. This mode especially benefits from the SPI direct
mode, as the data bytes are written head-to-head to the SPI bus,
without any additional addresses.
One use-case for this direct write mode is, programming a FPGA bitstream
image into the FPGA connected to the SPI bus at maximum speed.
This mode is described in chapter "22.5.2 Direct Write to SPI" in the
Marvell Armada XP Functional Spec Datasheet.

Pull more sound updates from Takashi Iwai:
"This is the second update round for 4.7-rc1. Most of changes are
about the pending ASoC updates and fixes, including a few new drivers.
Below are some highlights:
ASoC:
- New drivers for MAX98371 and TAS5720
- SPI support for TLV320AIC32x4, along with the module split
- TDM support for STI Uniperf IPs
- Remaining topology API fixes / updates
HDA:
- A couple of Dell quirks and new Realtek codec support"

Pull spi updates from Mark Brown:
"Another quiet release for SPI, almost entirely driver specific changes
with the diffstat dominated by two new drivers which are about two
thirds of it in terms of lines of code:
- new drivers for PIC32 standard and SQI controllers
- the Cadence driver has had runtime PM support added and quite a few
fixes and cleanups
- flash-specific accelerated path support now has a feature query
interface
- the pxa2xx driver has been moved to use the core DMA mapping support"
