commit 007773e16a6f3f49d1439554078c3ba8af131998 upstream.
Make use of a core helper to ensure the desired width is respected
when calling spi-mem operators.
Otherwise only the SPI controller will be matched with the flash chip,
which might lead to wrong widths. Also consider the width specified by
the user in the device tree.

commit c52c91bb9aa6bd8c38dbf9776158e33038aedd43 upstream.
When switching ChipSelect from default CS0 to any other CS, driver fails
to update the bits in system control module register that control which
CS is mapped for MMIO access. This causes reads to fail when driver
tries to access QSPI flash on CS1/2/3.
Fix this by updating appropriate bits whenever active CS changes.

commit ca59d5a51690d5b9340343dc36792a252e9414ae upstream.
When used in Extended SPI mode on LS1021A, the DSPI controller wants to
have the least significant 16-bit word written first to the TX FIFO.
In fact, the LS1021A reference manual says:
33.5.2.4.2 Draining the TX FIFO
When Extended SPI Mode (DSPIx_MCR[XSPI]) is enabled, if the frame size
of SPI Data to be transmitted is more than 16 bits, then it causes two
Data entries to be popped from TX FIFO simultaneously which are
transferred to the shift register. The first of the two popped entries
forms the 16 least significant bits of the SPI frame to be transmitted.
So given the following TX buffer:
+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+
| 0x0 | 0x1 | 0x2 | 0x3 | 0x4 | 0x5 | 0x6 | 0x7 | 0x8 | 0x9 | 0xa | 0xb |
+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+-----+
| 32-bit word 1 | 32-bit word 2 | 32-bit word 3 |
+-----------------------+-----------------------+-----------------------+
The correct way that a little-endian system should transmit it on the
wire when bits_per_word is 32 is:
0x03020100
0x07060504
0x0b0a0908
But it is actually transmitted as following, as seen with a scope:
0x01000302
0x05040706
0x09080b0a
It appears that this patch has been submitted at least once before:
https://lkml.org/lkml/2018/9/21/286
but in that case Chuanhua Han did not manage to explain the problem
clearly enough and the patch did not get merged, leaving XSPI mode
broken.

commit 63aa6a692595d47a0785297b481072086b9272d2 upstream.
Unlike irq_of_parse_and_map() which has a dummy definition on SPARC,
of_irq_to_resource() hasn't.
But as platform_get_irq() can be used instead and is generic, use it.

The problem comes from the error path which calls
irq_dispose_mapping() while the IRQ has been requested with
devm_request_irq().
IRQ doesn't need to be mapped with irq_of_parse_and_map(). The only
need is to get the IRQ virtual number. For that, use
of_irq_to_resource() instead of the
irq_of_parse_and_map()/irq_dispose_mapping() pair.

commit e9a8ba9769a0e354341bc6cc01b98aadcea1dfe9 upstream.
The channels spfi->tx_ch and spfi->rx_ch are not set to NULL after they
are released. As a result, they will be released again, either on the
error handling branch in the same function or in the corresponding
remove function, i.e. img_spfi_remove(). This patch fixes the bug by
setting the two members to NULL.

commit 9f918a728cf86b2757b6a7025e1f46824bfe3155 upstream.
This change is necessary for spidev devices (e.g. /dev/spidev3.0) working
in the slave mode (like NXP's dspi driver for Vybrid SoC).
When SPI HW works in this mode - the master is responsible for providing
CS and CLK signals. However, when some fault happens - like for example
distortion on SPI lines - the SPI Linux driver needs a chance to recover
from this abnormal situation and prepare itself for next (correct)
transmission.
This change doesn't pose any threat on drivers working in master mode as
spi_slave_abort() function checks if SPI slave mode is supported.

commit ada9e3fcc175db4538f5b5e05abf5dedf626e550 upstream.
This patch reverts commit 6e0a32d6f376 ("spi: dw: Fix default polarity
of native chipselect").
The SPI framework always called the set_cs callback with the logic
level it desired on the chip select line, which is what the drivers
original handling supported. commit f3186dd87669 ("spi: Optionally
use GPIO descriptors for CS GPIOs") changed these symantics, but only
in the case of drivers that also support GPIO chip selects, to true
meaning apply slave select rather than logic high. This left things in
an odd state where a driver that only supports hardware chip selects,
the core would handle polarity but if the driver supported GPIOs as
well the driver should handle polarity. At this point the reverted
change was applied to change the logic in the driver to match new
system.
This was then broken by commit 3e5ec1db8bfe ("spi: Fix SPI_CS_HIGH
setting when using native and GPIO CS") which reverted the core back
to consistently calling set_cs with a logic level.
This fix reverts the driver code back to its original state to match
the current core code. This is probably a better fix as a) the set_cs
callback is always called with consistent symantics and b) the
inversion for SPI_CS_HIGH can be handled in the core and doesn't need
to be coded in each driver supporting it.

commit 61acd19f9c56fa0809285346bd0bd4a926ab0da0 upstream.
To fix a regression on the Cadence SPI driver, this patch reverts
commit 6046f5407ff0 ("spi: cadence: Fix default polarity of native
chipselect").
This patch was not the correct fix for the issue. The SPI framework
calls the set_cs line with the logic level it desires on the chip select
line, as such the old is_high handling was correct. However, this was
broken by the fact that before commit 3e5ec1db8bfe ("spi: Fix SPI_CS_HIGH
setting when using native and GPIO CS") all controllers that offered
the use of a GPIO chip select had SPI_CS_HIGH applied, even for hardware
chip selects. This caused the value passed into the driver to be inverted.
Which unfortunately makes it look like a logical enable the chip select
value.
Since the core was corrected to not unconditionally apply SPI_CS_HIGH,
the Cadence driver, whilst using the hardware chip select, will deselect
the chip select every time we attempt to communicate with the device,
which results in failed communications.

commit 3e5ec1db8bfee845d9f8560d1c64aeaccd586398 upstream.
When improving the CS GPIO support at core level, the SPI_CS_HIGH
has been enabled for all the CS lines used for a given SPI controller.
However, the SPI framework allows to have on the same controller native
CS and GPIO CS. The native CS may not support the SPI_CS_HIGH, so they
should not be setup automatically.
With this patch the setting is done only for the CS that will use a
GPIO as CS

commit 7cbb16b2122c09f2ae393a1542fed628505b9da6 upstream.
Until a few years ago, this driver was only used with CS GPIO. The
only exception is CS0 on AT91RM9200 which has to use internal CS. A
limitation of the internal CS is that they don't support CS High.
So by using the CS GPIO the CS high configuration was available except
for the particular case CS0 on RM9200.
When the support for the internal chip-select was added, the check of
the CS high support was not updated. Due to this the driver accepts
this configuration for all the SPI controller v2 (used by all SoCs
excepting the AT91RM9200) whereas the hardware doesn't support it for
infernal CS.
This patch fixes the test to match the hardware capabilities.

As devm_spi_register_master() is used during probe, spi_master_put()
mustn't be called in .remove() callback.
It fixes the following kernel WARNING/Oops when executing

commit f6910679e17ad4915f008bd2c614d38052426f7c upstream.
Later versions of the QSPI controller (e.g. in i.MX6UL/ULL and i.MX7)
seem to have an additional TDH setting in the FLSHCR register, that
needs to be set in accordance with the access mode that is used (DDR
or SDR).
Previous bootstages such as BootROM or bootloader might have used the
DDR mode to access the flash. As we currently only use SDR mode, we
need to make sure the TDH bits are cleared upon initialization.

by pm_runtime_enable() would disturb the balance of the Force.
In practice, this happens if we fail to allocate any of the GPIOS ("cs",

commit 8d8bef50365847134b51c1ec46786bc2873e4e47 upstream.
Commit 6935224da248 ("spi: bcm2835: enable support of 3-wire mode")
added 3-wire support to the BCM2835 SPI driver by setting the REN bit
(Read Enable) in the CS register when receiving data. The REN bit puts
the transmitter in high-impedance state. The driver recognizes that
data is to be received by checking whether the rx_buf of a transfer is
non-NULL.
Commit 3ecd37edaa2a ("spi: bcm2835: enable dma modes for transfers
meeting certain conditions") subsequently broke 3-wire support because
it set the SPI_MASTER_MUST_RX flag which causes spi_map_msg() to replace
rx_buf with a dummy buffer if it is NULL. As a result, rx_buf is
*always* non-NULL if DMA is enabled.
Reinstate 3-wire support by not only checking whether rx_buf is non-NULL,
but also checking that it is not the dummy buffer.

atmel_spi f0000000.spi: Using dma0chan2 (tx) and dma0chan3 (rx)

atmel_spi: probe of f0000000.spi failed with error -22
Commit 0a919ae49223 ("spi: Don't call spi_get_gpio_descs() before device name is set")
moved the calling of spi_get_gpio_descs() after ctrl->dev is set,
but didn't move the !ctrl->num_chipselect check. When there are
chip selects in the device tree, the spi-atmel driver lets the
SPI core discover them when registering the SPI master.
The ctrl->num_chipselect is thus expected to be set by
spi_get_gpio_descs().
Move the !ctlr->num_chipselect after spi_get_gpio_descs() as it was
before the aforementioned commit. While touching this block, get rid
of the explicit comparison with 0 and update the commenting style.

[ Upstream commit 47300728fb213486a830565d2af49da967c9d16a ]
This fixes tx and bi-directional dma transfers on rk3399-gru-kevin.
It seems the SPI fifo must have room for 2 bursts when the dma_tx_req
signal is generated or it might skip some words. This in turn makes
the rx dma channel never complete for bi-directional transfers.
Fix it by setting tx burst length to fifo_len / 4 and the dma
watermark to fifo_len / 2.
However the rk3399 TRM says (sic):
"DMAC support incrementing-address burst and fixed-address burst. But in
the case of access SPI and UART at byte or halfword size, DMAC only
support fixed-address burst and the address must be aligned to word."
So this relies on fifo_len being a multiple of 16 such that the
burst length (= fifo_len / 4) is a multiple of 4 and the addresses
will be word-aligned.
