spi: cadence-quadspi: allow operations with cmd/addr buswidth >1
With the removal of the incorrect logic of cqspi_set_protocol(), ops with
cmd/addr buswidth >1 are now working correctly.

Tested on a TI AM64x with a Macronix MX25U51245G QSPI flash using 1-4-4
operations.

DTR operations are currently untested, so we leave them disabled for now
(except for the previously allowed 8-8-8 ops).

spi: cadence-quadspi: drop cqspi_set_protocol()
As suggested, this removes the whole cqspi_set_protocol() function, as it
is not actually needed:

- Checks for unsupported operations are already handled by supports_op(),
  removing the need to distinguish DTR and non-DTR modes in the buswidth
  setup
- supports_op() ensures that the DTR flags match for all relevant parts of
  an operation, so op->cmd.dtr can be used instead of copying the flag to
  the cqspi_flash_pdata
- The logic in cqspi_set_protocol() is moved to cqspi_calc_rdreg() and
  cqspi_write_setup() (with a helper macro CQSPI_OP_WIDTH())

The helper macro checks nbytes instead of buswidth for 0, for consistency
with supports_op() etc.

spi: rockchip: fix missing error on unsupported SPI_CS_HIGH
The hardware (except for the ROCKCHIP_SPI_VER2_TYPE2 version) does not
support active-high native chip selects. However if such a CS is configured
the core does not error as it normally should, because the
'ctlr->use_gpio_descriptors = true' line in rockchip_spi_probe() makes the
core set SPI_CS_HIGH in ctlr->mode_bits.

In such a case the spi-rockchip driver operates normally but produces an
active-low chip select signal without notice.

There is no provision in the current core code to handle this
situation. Fix by adding a check in the ctlr->setup function (similarly to
what spi-atmel.c does).

This cannot be done reading the SPI_CS_HIGH but in ctlr->mode_bits because
that bit gets always set by the core for master mode (see above).

spi: ingenic: Add support for new Ingenic SoCs.
1.Since it would be dangerous to specify a newer SoC's compatible
  string as the fallback of an older SoC's compatible string, we
  add support for the "ingenic,jz4775-spi" compatible string in
  the driver.

  This will permit to support the JZ4775 by having:
  compatible = "ingenic,jz4775-spi";

  Instead of doing:
  compatible = "ingenic,jz4775-spi", "ingenic,jz4780-spi";

2.Add support for probing the spi-ingenic driver on the X1000 SoC
  from Ingenic. From the X1000 SoC onwards, the maximum frequency
  allowed by the SSI module of Ingenic SoCs has been changed from
  54MHz to 50MHz. So "max_speed_hz" is introduced in "jz_soc_info"
  to set different maximum frequency values.

3.Add support for probing the spi-ingenic driver on the X2000 SoC
  from Ingenic. The X2000 SoC has only one native chip select line,
  so "max_native_cs" is introduced in "jz_soc_info" to set different
  maximum number of native chip select lines.

4.Because of the introduction of support for the X-series SoCs, the
  current driver is not only applicable to the JZ-series SoCs, so
  the description texts has been modified to avoid misunderstanding.

spi: spi-mem: check if data buffers are on stack
The buffers passed in the data phase must be DMA-able. Programmers often

stack. This can be hard to spot when reviewing code. Reject ops if their
data buffer is on the stack to avoid this.

58d37dc1df ARM: omap1: move perseus spi pinconf to board file
The driver has always had a FIXME about this, and it seems
like this trivial code move avoids a mach header inclusion,
so just do it.

With that out of the way, and the header file inclusions
changed to global files, the driver can also be compile-tested
on other platforms.

spi: intel: Implement dirmap hooks
Currently the driver goes over the supported opcodes list each time
->exec_op() is called and finds the suitable for the given operation.
This consumes unnecessary amount of CPU cycles because the operation is
always the same. For this reason populate dirmap hooks for the driver so
that we cache the selected operation and then simply call it on each
read/write.

spi: cadence-quadspi: fix incorrect supports_op() return value
Since the conversion to spi-mem, the driver advertised support for
various operations that cqspi_set_protocol() was never expected to handle
correctly - in particuar all non-DTR operations with command or address
buswidth > 1. For DTR, all operations except for 8-8-8 would fail, as
cqspi_set_protocol() returns -EINVAL.

In non-DTR mode, this resulted in data corruption for SPI-NOR flashes that
support such operations. As a minimal fix that can be backported to stable
kernels, simply disallow the unsupported operations again to avoid this
issue.

spi: core: Only check bits_per_word validity when explicitly provided
On SPI device probe, the core will call spi_setup in spi_add_device
before the corresponding driver was probed. When this happens, the
bits_per_word member of the device is not yet set by the driver,
resulting in the default being set to 8 bits-per-word.

However some controllers do not support 8 bits-per-word at all, which
results in a failure when checking the bits-per-word validity.

In order to support these devices, skip the bits-per-word validity
check when it is not explicitly provided by drivers.

spi: spidev: replace usage of found with dedicated list iterator variable
To move the list iterator variable into the list_for_each_entry_*()
macro in the future it should be avoided to use the list iterator
variable after the loop body.

To *never* use the list iterator variable after the loop it was
concluded to use a separate iterator variable instead of a
found boolean [1].

This removes the need to use a found variable and simply checking if
the variable was set, can determine if the break/goto was hit.

ad9c6ee642 spi: Updates for v5.18
The overwhelming bulk of this pull request is a change from Uwe
 Kleine-König which changes the return type of the remove() function to
 void as part of some wider work he's doing to do this for all bus types,
 causing updates to most SPI device drivers.  The branch with that on has
 been cross merged with a couple of other trees which added new SPI
 drivers this cycle, I'm not expecting any build issues resulting from
 the change.
 
 Otherwise it's been a relatively quiet release with some new device
 support, a few minor features and the welcome completion of the
 conversion of the subsystem to use GPIO descriptors rather than numbers:
 
  - Change return type of remove() to void.
  - Completion of the conversion of SPI controller drivers to use GPIO
    descriptors rather than numbers.
  - Quite a few DT schema conversions.
  - Support for multiple SPI devices on a bus in ACPI systems.
  - Big overhaul of the PXA2xx SPI driver.
  - Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
    MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and
    Sunplus SP7021.

spi: fsi: Implement a timeout for polling status
The data transfer routines must poll the status register to
determine when more data can be shifted in or out. If the hardware
gets into a bad state, these polling loops may never exit. Prevent
this by returning an error if a timeout is exceeded.

spi: Fix erroneous sgs value with min_t()
While computing sgs in spi_map_buf(), the data type
used in min_t() for max_seg_size is 'unsigned int' where
as that of ctlr->max_dma_len is 'size_t'.

min_t(unsigned int,x,y) gives wrong results if one of x/y is
'size_t'

Consider the below examples on a 64-bit machine (ie size_t is
64-bits, and unsigned int is 32-bit).
    case 1) min_t(unsigned int, 5, 0x100000001);
    case 2) min_t(size_t, 5, 0x100000001);

Case 1 returns '1', where as case 2 returns '5'. As you can see
the result from case 1 is wrong.

This patch fixes the above issue by using the data type of the
parameters that are used in min_t with maximum data length.

spi: Fix invalid sgs value

(for eg:-RZ_DMAC driver sets dma_set_max_seg_size as U32_MAX)
When this value is used in min_t() as an integer type, it becomes
-1 and the value of sgs becomes 0.

Fix this issue by replacing the 'int' data type with 'unsigned int'
in min_t().

spi: use specific last_cs instead of last_cs_enable
Commit d40f0b6f2e instroduced last_cs_enable to avoid setting
chipselect if it's not necessary, but it also introduces a bug. The
chipselect may not be set correctly on multi-device SPI busses. The
reason is that we can't judge the chipselect by bool last_cs_enable,
since chipselect may be modified after other devices were accessed.

So we should record the specific state of chipselect in case of
confusion.

spi: stm32: ignore Rx queue not empty in stm32f4 Tx only mode
STM32F4_SPI_SR_RXNE and STM32F4_SPI_SR_OVR are distinct bits in the same
status register.  ~STM32F4_SPI_SR_OVR | STM32F4_SPI_SR_RXNE is thus
equal to ~STM32F4_SPI_SR_OVR.

The original intention was likely for transmission-only transfers to
ignore interrupts both for when the Rx queue has bytes (RXNE) as well
as when these bytes haven't been read in time (OVR).

Fix the typo by adding the missing parenthesis.

mtd: spi-nor / spi / MFD: Convert intel-spi to SPI MEM
Merge series from Mika Westerberg <mika.westerberg@linux.intel.com>:

Based on discussion on the patch I sent some time ago here:

  http://lists.infradead.org/pipermail/linux-mtd/2021-June/086867.html

it turns out that the preferred way to deal with the SPI flash controller
drivers is through SPI MEM which is part of Linux SPI subsystem.

This series does that for the intel-spi driver. This also renames the
driver to follow the convention used in the SPI subsystem. The first patch
improves the write protection handling to be slightly more safer. The
following two patches do the conversion itself. Note the Intel SPI flash
controller only allows commands such as read, write and so on and it
internally uses whatever addressing etc. it figured from the SFDP on the
flash device.

00360ebae4 spi: mxic: Add support for pipelined ECC operations
Some SPI-NAND chips do not have a proper on-die ECC engine providing
error correction/detection. This is particularly an issue on embedded
devices with limited resources because all the computations must
happen in software, unless an external hardware engine is provided.

These external engines are new and can be of two categories: external
or pipelined. Macronix is providing both, the former being already
supported. The second, however, is very SoC implementation dependent
and must be instantiated by the SPI host controller directly.

An entire subsystem has been contributed to support these engines which
makes the insertion into another subsystem such as SPI quite
straightforward without the need for a lot of specific functions.

spi: make remove callback a void function
The value returned by an spi driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)

So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

spi: spi-zynq-qspi: Fix a NULL pointer dereference in zynq_qspi_exec_mem_op()
In zynq_qspi_exec_mem_op(), kzalloc() is directly used in memset(),
which could lead to a NULL pointer dereference on failure of
kzalloc().

Fix this bug by adding a check of tmpbuf.

This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.

Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.

Builds with CONFIG_SPI_ZYNQ_QSPI=m show no new warnings,
and our static analyzer no longer warns about this code.

The driver should get spi_master from the platform device and retrieve
the private data from it.

These patches is mainly for adding mt8186 support.
The spi nor controller of mt8186 has some differences,
it needs one more clk, axi_s, for dma feature.
And also needs one extra dummy bit when read flash registers.

spi: s3c24xx: Convert to GPIO descriptors
This driver has a bunch of custom oldstyle GPIO number-passing
fields and a custom set-up callback.

The good thing is: nothing in the kernel is using it.

Convert the driver to use GPIO descriptors with a SPI_MASTER_GPIO_SS
flag so that the local CS callback also get invoked as the hardware
needs this.

New users of this driver can provide GPIO descriptor tables like
the other converted drivers.

spi: stm32: make SPI_MASTER_MUST_TX flags only specific to STM32F4
Commit 61367d0b8f ("spi: stm32: Add 'SPI_SIMPLEX_RX', 'SPI_3WIRE_RX' support for stm32f4")
allowed to properly communicate with the st-gyro-spi even when
there is no tx_buf provided by setting the flag SPI_MASTER_MUST_TX and
thus forcing a dummy TX buffer to work in Full Duplex.
This behavior should kept only for the STM32F4 and not for other
compatible since the STM32H7 do support SIMPLEX_RX and SIMPLEX_TX.
Add the flags variable within the struct stm32_spi_cfg so that flags
used at master registration time are compatible specific.

spi: stm32-qspi: Update spi registering
Some device driver need to communicate to qspi device during the remove
process, qspi controller must be functional when spi_unregister_master()
is called.

To ensure this, replace devm_spi_register_master() by spi_register_master()
and spi_unregister_master() is called directly in .remove callback before
stopping the qspi controller.

This issue was put in evidence using kernel v5.11 and later
with a spi-nor which supports the software reset feature introduced
by commit d73ee7534c ("mtd: spi-nor: core: perform a Soft Reset on
shutdown")

3ceff4ea07 sound updates for 5.17-rc1
It's a relatively calm development cycle, but still lots of updates in
 the driver side like Intel SOF.  Below are some highlights:
 
 * ALSA / ASoC core:
 - A new kselftest for ALSA control API
 - PCM NO_REWINDS support
 - Potential race fixes around control removals
 - Unify x86 SG-buffer memory allocation code
 - Cleanups and race fixes for ASoC DPCM locking
 
 * ASoC:
 - Refinements and cleanups around the delay() APIs
 - Wider use of dev_err_probe().
 - Continuing cleanups and improvements to the SOF code
 - Support for pin switches in simple-card derived cards
 - Support for AMD Renoir ACP, Asahi Kasei Microdevices AKM4375, Intel
   systems using NAU8825 and MAX98390, Mediatek MT8915, nVidia Tegra20
   S/PDIF, Qualcomm systems using ALC5682I-VS and Texas Instruments
   TLV320ADC3xxx
 
 * HD-audio / USB-audio:
 - Fix deadlock at HD-audio codec unbinding
 - Fixes for Tegra194 HD-audio, new HDA support for CS35L41 codec
 - Quirks for Lenovo and HP machines, Gigabyte mobo, Bose device
 
 * Misc:
 - Fix virmidi drain behavior
 
 Note that the merge of CS35L41 codec support is still half-baked, and
 at least one ACPI change is missing.  Although this won't hinder the
 kernel build itself, we're going to catch up before RC1.

Add missing pm_runtime_disable() for meson_spifc_probe.

spi: qcom: geni: handle timeout for gpi mode
We missed adding handle_err for gpi mode, so add a new function
spi_geni_handle_err() which would call handle_fifo_timeout() or newly
added handle_gpi_timeout() based on mode

spi: qcom: geni: set the error code for gpi transfer
Before we invoke spi_finalize_current_transfer() in
spi_gsi_callback_result() we should set the spi->cur_msg->status as
appropriate (0 for success, error otherwise).

The helps to return error on transfer and not wait till it timesout on
error

spi: uniphier: Fix a bug that doesn't point to private data correctly
In uniphier_spi_remove(), there is a wrong code to get private data from
the platform device, so the driver can't be removed properly.

The driver should get spi_master from the platform device and retrieve
the private data from it.
