Fixes: computation of actual bytes to fill/receive in/from FIFO in unpacked
mode when transfer length is not a multiple of requested bits per word.
unpacked mode transfers fails when the transfer includes partial bytes in
the last word.
Total words to be written/read to/from FIFO is computed based on transfer
length and bits per word. Unpacked mode includes 0 padding bytes for partial
words to align with bits per word and these extra bytes are also accounted
for calculating bytes left to transfer in the current driver.
This causes extra bytes access of tx/rx buffers along with buffer index
position crossing actual length where remain_len becomes negative and due to
unsigned type, negative value is a 32 bit representation of signed value
and transferred bytes never meets the actual transfer length resulting in
transfer timeout and a hang.
This patch fixes this with proper computation of the actual bytes to fill in
FIFO during transmit and the actual bytes to read from FIFO during receive
ignoring 0 padded bytes.

To transfer via SPI the tegra20-slink driver first sets the command
register, which contains the chip select value, and after that the
command2 register, which contains the chip select line. This leads to a
small spike in the chip selct 0 line between the set of the value and
the selection of the chip select line.
This commit changes the order of the register writes so that first the
chip select line is chosen and then the value is set, removing the
spike.

If we don't use CONT to keep SS activated or use DMA mode without
cs-gpio, SS will be inactivated between every words. The word here
means the data sent once which length can be set as 1/2/4 bytes.
In the isr function, we read the FSR_RXCOUNT just behind the
fsl_lpspi_read_rx_fifo. This causes the value of FSR_RXCOUNT cannot
reflect whether there is still data not sent timely. So do this
judgement by FSR_TXCOUNT.

While the sequencer is reset after each SPI message since commit
880c6d114fd79a69 ("spi: rspi: Add support for Quad and Dual SPI
Transfers on QSPI"), it was never reset for the first message, thus
relying on reset state or bootloader settings.

The Renesas RSPI/QSPI driver performs SPI controller register
initialization in its spi_operations.setup() callback, without calling
pm_runtime_get_sync() first, which may cause spurious failures.
So far this went unnoticed, as this SPI controller is typically used
with a single SPI NOR FLASH containing the boot loader:
1. If the device's module clock is still enabled (left enabled by the
bootloader, and not yet disabled by the clk_disable_unused() late
initcall), register initialization succeeds,
2. If the device's module clock is disabled, register writes don't
seem to cause lock-ups or crashes.
Data received in the first SPI message may be corrupted, though.
Subsequent SPI messages seem to be OK.
E.g. on r8a7791/koelsch, one bit is lost while receiving the 6th
byte of the JEDEC ID for the s25fl512s FLASH, corrupting that byte
and all later bytes. But until commit a2126b0a010905e5 ("mtd:
spi-nor: refine Spansion S25FL512S ID"), the 6th byte was not
considered for FLASH identification.
Fix this by moving all initialization from the .setup() to the
.prepare_message() callback. The latter is always called after the
device has been runtime-resumed by the SPI core.
This also makes the driver follow the rule that .setup() must not change
global driver state or register values, as that might break a transfer
in progress.

Commit 71abd29057cb ("spi: imx: Add support for SPI Slave mode") added
an RX FIFO flush before start of a transfer. In slave mode, the master
may have sent more data than expected and this data will still be in the
RX FIFO at the start of the next transfer, and so needs to be flushed.
However, the code to do the flush was accidentally saving this data into
the previous transfer's RX buffer, clobbering the contents of whatever
followed that buffer.
Change it to empty the FIFO and throw away the data. Every one of the
RX functions for the different eCSPI versions and modes reads the RX
FIFO data using the same readl() call, so just use that, rather than
using the spi_imx->rx function pointer and making sure all the different
rx functions have a working "throw away" mode.
There is another issue, which affects master mode when switching from
DMA to PIO. There can be extra data in the RX FIFO which triggers this
flush code, causing memory corruption in the same manner. I don't know
why this data is unexpectedly in the FIFO. It's likely there is a
different bug or erratum responsible for that. But regardless of that,
I think this is proper fix the for bug at hand here.

This fixes a bug for messages containing both zero length and
unidirectional xfers.
The function spi_map_msg will allocate dummy tx and/or rx buffers
for use with unidirectional transfers when the hardware can only do
a bidirectional transfer. That dummy buffer will be used in place
of a NULL buffer even when the xfer length is 0.
Then in the function __spi_map_msg, if he hardware can dma,
the zero length xfer will have spi_map_buf called on the dummy
buffer.
Eventually, __sg_alloc_table is called and returns -EINVAL
because nents == 0.
This fix prevents the error by not using the dummy buffer when
the xfer length is zero.

The NXP's Vybryd vf610 can work as a SPI slave device (the CS and clock
signals are provided by master).
It is possible to specify a single device to work in that mode. As we do
use DMA for transferring data, the RX channel must be prepared for
incoming data.
Moreover, in slave mode we just set a subset of control fields in
configuration registers (CTAR0, PUSHR).
For testing the spidev_test program has been used.

Some devices are slow and cannot keep up with the SPI bus and therefore
require a short delay between words of the SPI transfer.
The example of this that I'm looking at is a SAMA5D2 with a minimum SPI
clock of 400kHz talking to an AVR-based SPI slave. The AVR cannot put
bytes on the bus fast enough to keep up with the SoC's SPI controller
even at the lowest bus speed.
This patch introduces the ability to specify a required inter-word
delay for SPI devices. It is up to the controller driver to configure
itself accordingly in order to introduce the requested delay.
Note that, for spi_transfer, there is already a field word_delay that
provides similar functionality. This field, however, is specified in
clock cycles (and worse, SPI controller cycles, not SCK cycles); that
makes this value dependent on the master clock instead of the device
clock for which the delay is intended to provide some relief. This
patch leaves this old word_delay in place and provides a time-based
word_delay_us alongside it; the new field fits in the struct padding
so struct size is constant. There is only one in-kernel user of the
word_delay field and presumably that driver could be reworked to use
the time-based value instead.
The time-based delay is limited to 8 bits as these delays are intended
to be short. The SAMA5D2 that I've tested this on limits delays to a
maximum of ~100us, which is already many word-transfer periods even at
the minimum transfer speed supported by the controller.

- Add driver for NXP FlexSPI host controller
(0) What is the FlexSPI controller?
FlexSPI is a flexsible SPI host controller which supports two SPI
channels and up to 4 external devices. Each channel supports
Single/Dual/Quad/Octal mode data transfer (1/2/4/8 bidirectional
data lines) i.e. FlexSPI acts as an interface to external devices,
maximum 4, each with up to 8 bidirectional data lines.
It uses new SPI memory interface of the SPI framework to issue
flash memory operations to up to four connected flash
devices (2 buses with 2 CS each).
(1) Tested this driver with the mtd_debug and JFFS2 filesystem utility
on NXP LX2160ARDB and LX2160AQDS targets.
LX2160ARDB is having two NOR slave device connected on single bus A
i.e. A0 and A1 (CS0 and CS1).
LX2160AQDS is having two NOR slave device connected on separate buses
one flash on A0 and second on B1 i.e. (CS0 and CS3).
Verified this driver on following SPI NOR flashes:
Micron, mt35xu512ab, [Read - 1 bit mode]
Cypress, s25fl512s, [Read - 1/2/4 bit mode]
