Let's set the 'use_gpio_descriptors' field so that we use the new way of
requesting the CS GPIOs in the core. This allows us to avoid having to
configure the CS pins in "output" mode with an 'output-enable' pinctrl
setting.

There isn't any need to overwrite the mode here in the driver with what
has been detected by the firmware, such as DT or ACPI. In fact, if we
use the SPI CS gpio descriptor feature we will overwrite the mode with
SPI_MODE_0 where it already contains SPI_MODE_0 and more importantly
SPI_CS_HIGH. Clearing the SPI_CS_HIGH bit causes the CS line to toggle
when the device is probed when it shouldn't change, confusing the driver
and making it fail to probe. Drop the assignment and let the spi core
take care of it.

The Canaan Kendryte K210 RISC-V SoC includes a DW apb_ssi v4 controller
which is documented to have a 32 words deep TX and RX FIFO. The FIFO
length detection in spi_hw_init() correctly detects this value.
However, when the controller RX FIFO is filled up to 32 entries
(RXFLR = 32), an RX FIFO overrun error occurs. This likely due to a
hardware bug which can be avoided by force setting the fifo_len field of
struct dw_spi to 31.
Define the dw_spi_canaan_k210_init() function to force set fifo_len to
31 when the device node compatible string is "canaan,k210-spi".

The Synopsis DesignWare DW_apb_ssi specifications version 3.23 onward
define a 32-bits maximum transfer size synthesis parameter
(SSI_MAX_XFER_SIZE=32) in addition to the legacy 16-bits configuration
(SSI_MAX_XFER_SIZE=16) for SPI controllers. When SSI_MAX_XFER_SIZE=32,
the layout of the ctrlr0 register changes, moving the data frame format
field from bits [3..0] to bits [16..20], and the RX/TX FIFO word size
can be up to 32-bits.
To support this new format, introduce the DW SPI capability flag
DW_SPI_CAP_DFS32 to indicate that a controller is configured with
SSI_MAX_XFER_SIZE=32. Since SSI_MAX_XFER_SIZE is a controller synthesis
parameter not accessible through a register, the detection of this
parameter value is done in spi_hw_init() by writing and reading the
ctrlr0 register and testing the value of bits [3..0]. These bits are
ignored (unchanged) for SSI_MAX_XFER_SIZE=16, allowing the detection.
If a DFS32 capable SPI controller is detected, the new field dfs_offset
in struct dw_spi is set to SPI_DFS32_OFFSET (16).
dw_spi_update_config() is modified to set the data frame size field at
the correct position is the CTRLR0 register, as indicated by the
dfs_offset field of the dw_spi structure.
The DW_SPI_CAP_DFS32 flag is also unconditionally set for SPI slave
controllers, e.g. controllers that have the DW_SPI_CAP_DWC_SSI
capability flag set. However, for these ssi controllers, the dfs_offset
field is set to 0 as before (as per specifications).
Finally, for any controller with the DW_SPI_CAP_DFS32 capability flag
set, dw_spi_add_host() extends the value of bits_per_word_mask from
16-bits to 32-bits. dw_reader() and dw_writer() are also modified to
handle 32-bits iTX/RX FIFO words.

atmel_qspi_remove() accesses the driver's private data after calling
spi_unregister_controller() even though that function releases the last
reference on the spi_controller and thereby frees the private data.
Fix by switching over to the new devm_spi_alloc_master() helper which
keeps the private data accessible until the driver has unbound.

If the call to devm_spi_register_controller() fails on probe of the
Qualcomm Atheros AR934x/QCA95xx SPI driver, the spi_controller struct is
erroneously not freed. Fix by switching over to the new
devm_spi_alloc_master() helper.
Moreover, the controller's clock is enabled on probe but not disabled if
any of the subsequent probe steps fail.
Finally, there's an ordering issue in ar934x_spi_remove() wherein the
clock is disabled even though the controller is not yet unregistered.
It is unregistered after ar934x_spi_remove() by the devres framework.
As long as it is not unregistered, SPI transfers may still be ongoing
and disabling the clock may break them. It is not possible to use
devm_spi_register_controller() in this case, so move to the non-devm
variant.
All of these bugs have existed since the driver was first introduced,
so it seems fair to fix them together in a single commit.

Commit 702b15cb9712 ("spi: mt7621: fix missing clk_disable_unprepare()

errors, but only did so for 2 of 3 potentially failing calls: The clock
needs to be disabled on failure of devm_spi_register_controller() as
well.
Moreover, the commit purports to fix a bug in commit cbd66c626e16 ("spi:

If the call to devm_spi_register_master() fails on probe of the GPIO SPI
driver, the spi_master struct is erroneously not freed:
After allocating the spi_master, its reference count is 1. The driver
unconditionally decrements the reference count on unbind using a devm
action. Before calling devm_spi_register_master(), the driver
unconditionally increments the reference count because on success,
that function will decrement the reference count on unbind. However on
failure, devm_spi_register_master() does *not* decrement the reference
count, so the spi_master is leaked.
The issue was introduced by commits 8b797490b4db ("spi: gpio: Make sure
spi_master_put() is called in every error path") and 79567c1a321e ("spi:
gpio: Use devm_spi_register_master()"), which sought to plug leaks
introduced by 9b00bc7b901f ("spi: spi-gpio: Rewrite to use GPIO
descriptors") but missed this remaining leak.
The situation was later aggravated by commit d3b0ffa1d75d ("spi: gpio:
prevent memory leak in spi_gpio_probe"), which introduced a
use-after-free because it releases a reference on the spi_master if
devm_add_action_or_reset() fails even though the function already
does that.

QSPI_IFR is set as the last QSPI Instruction Frame register
regardless of the sama5d2 or sam9x60 version of the IP. Move
the writing of QSPI_IFR outside of the IP specific code.

That bit describes the APB transfer type. We are writing
serial memory registers via AHB acesses, that bit does not
make sense in the current context.

Following error was seen when mounting a 16MByte ubifs:
UBIFS error (ubi0:0 pid 1893): check_lpt_type.constprop.6: invalid type (15) in LPT node type
QSPI_IFR.TFRTYP was not set correctly. When data transfer is enabled
and one wants to access the serial memory through AHB in order to:
- read in the serial memory, but not a memory data, for example
a JEDEC-ID, QSPI_IFR.TFRTYP must be written to '0' (both sama5d2
and sam9x60).
- read in the serial memory, and particularly a memory data,
TFRTYP must be written to '1' (both sama5d2 and sam9x60).
- write in the serial memory, but not a memory data, for example
writing the configuration or the QSPI_SR, TFRTYP must be written
to '2' for sama5d2 and to '0' for sam9x60.
- write in the serial memory in particular to program a memory data,
TFRTYP must be written to '3' for sama5d2 and to '1' for sam9x60.
Fix the setting of the QSPI_IFR.TFRTYP field.
