Once a spi_master_get() call succeeds, we need an additional

leak a reference to master. Fix by removing the unnecessary

We had set the platform drvdata in rspi_probe() as a type of
struct rspi_data, but use it as struct spi_master in rspi_remove()
Fix by remove the unnecessary spi_master_[get|put]() since rspi->master
is no longer used after spi_unregister_master().

There is a bug in qspi removal path, as a result of which
qspi cannot be removed when used as a module. The patch
solves the bug and qspi can be removed cleanly.
The bugs fixed are:
-pm_runtime used around register access.
- pm_runtime_disable need to be done before removal.
- spi_unregister_master need to be called to unregister
the spi device.
Tested on DRA7 board.

devres_add() should be called when the action to be undone succeeded,
not when it failed. Fix the inverted test in devm_spi_register_master()
which was doing the opposite.
The user-visible issue without this fix is:
insmod spi-tegra114.ko
Assume there's an MTD device on that SPI bus, which creates /dev/mtd0.
rmmod spi-tegra114
Doesn't remove devices on the SPI bus.
insmod spi-tegra114.ko
Creates a duplicate SPI device which creates /dev/mtd1.
hexdump -C /dev/mtd0
That's the old device, which uses an SPI bus hosted by a non-existent
module, which causes the oops below.

Current spi bus_num.chip_select "spix.y" based device naming scheme may not
be stable enough to be used in name based matching, for instance within
ALSA SoC subsystem.
This can be problem in PC kind of platforms if there are changes in SPI bus
configuration, amount of busses or probe order.
This patch addresses the problem by using the ACPI device name with
"spi-" prefix for ACPI enumerated SPI slave. For them device name
"spix.y" becomes "spi-INTABCD:ij".

Modify struct acpi_dev_node to contain a pointer to struct acpi_device
associated with the given device object (that is, its ACPI companion
device) instead of an ACPI handle corresponding to it. Introduce two
new macros for manipulating that pointer in a CONFIG_ACPI-safe way,
ACPI_COMPANION() and ACPI_COMPANION_SET(), and rework the
ACPI_HANDLE() macro to take the above changes into account.
Drop the ACPI_HANDLE_SET() macro entirely and rework its users to
use ACPI_COMPANION_SET() instead. For some of them who used to
pass the result of acpi_get_child() directly to ACPI_HANDLE_SET()
introduce a helper routine acpi_preset_companion() doing an
equivalent thing.
The main motivation for doing this is that there are things
represented by struct acpi_device objects that don't have valid
ACPI handles (so called fixed ACPI hardware features, such as
power and sleep buttons) and we would like to create platform
device objects for them and "glue" them to their ACPI companions
in the usual way (which currently is impossible due to the
lack of valid ACPI handles). However, there are more reasons
why it may be useful.
First, struct acpi_device pointers allow of much better type checking
than void pointers which are ACPI handles, so it should be more
difficult to write buggy code using modified struct acpi_dev_node
and the new macros. Second, the change should help to reduce (over
time) the number of places in which the result of ACPI_HANDLE() is
passed to acpi_bus_get_device() in order to obtain a pointer to the
struct acpi_device associated with the given "physical" device,
because now that pointer is returned by ACPI_COMPANION() directly.
Finally, the change should make it easier to write generic code that
will build both for CONFIG_ACPI set and unset without adding explicit
compiler directives to it.

If the SPI device is enumerated from ACPI namespace (it has an ACPI handle)
it might have ACPI methods that needs to be called in order to transition
the device to different power states (such as _PSx).
We follow what has been done for platform and I2C buses here and attach the
SPI device to the ACPI power domain if the device has an ACPI handle. This
makes sure that the device is powered on when its ->probe() is called.
For non-ACPI devices this patch is a no-op.

usual for this cycle with lots of clean-up.
- Cross arch clean-up and consolidation of early DT scanning code.
- Clean-up and removal of arch prom.h headers. Makes arch specific
prom.h optional on all but Sparc.
- Addition of interrupts-extended property for devices connected to
multiple interrupt controllers.
- Refactoring of DT interrupt parsing code in preparation for
deferred probe of interrupts.
- ARM cpu and cpu topology bindings documentation.
- Various DT vendor binding documentation updates"

The tegra114 driver wasn't currently handling the cs_change
functionality. cs_change is meant to invert the decisions of whether
or not to deactivate CS after each transfer. Without cs_change, after
every transfer (other than the last in the message) the normal behavior
is to leave CS active. For the last transfer, normally CS is
deactivated when the transfer is complete.
With cs_change set on a transfer (other than last one) CS would be
deactivated and the next transfer would need to activate it again. If
cs_change was set on the last tranfer in a message, then CS would be
left active when the message compeleted.
Also, this builds in logic so that if a different device tries to start
a transfer while CS is active from a different device, it will abort the
previous transfer and start a new one for the new device.
This splits tegra_spi_start_transfer_one into 2 functions, the new one
being tegra_spi_setup_transfer_one. The setup function is safe to call
on all transfers, sets up for the transfer, and handles the special case
of the first transfer in a message. In this special case, it needs to
know whether or not it needs to activate CS.
This work was based on the spi-atmel driver.

This is more idiomatic for the factored out message processing and gives a
small simplification of the code since we always set the per-transfer
parameters in the same fashion.

This is a half done conversion with minimal code reorganisation provided
for bisection purposes. A further patch will move the first transfer
preparation into tegra_slink_prepare_message().
The cs_change and udelay handling is removed, these should be
implemented by the framework and in any case are buggy - the two fields
should not be related and the cs_change handling appears to at best only
work the first time it's used in a message.

The R8A7790 has QSPI module which added into RSPI together.
The transmit or receive data should be read from or written to
with the longword-, word-, or byte-access width. Modify word-
access to byte-access. In 16-bit data register, QSPI send or
receive datas access from high 8-bit while RSPI send or receive
datas access from low 8-bit on single mode.
Modify to reset transmit-receive buffer data and reading dummy
after data are transmited. RSPI has a TXMD bit on control
register(SPCR) to set transmit-only mode when transmit data or
Full-duplex synchronous mode when receive data. In QSPI the TXMD
bit is not supported, so after transmit data, dummy should be
read and before transmit or receive data the bufer register
should be reset.
This driver is the implementation of send and receive pio only,
DMA is not supported at this time.
Without this patch, it will occur error when transmit and receive
