[ Upstream commit b6e05ba0844139dde138625906015c974c86aa93 ]

It is not valid to call pm_runtime_set_suspended() for devices
with runtime PM enabled because it returns -EAGAIN if it is enabled
already and working. So, call pm_runtime_disable() before to fix it.

[ Upstream commit ce1dac560a74220f2e53845ec0723b562288aed4 ]

While in commit 2dd33f9cec90 ("spi: imx: support DMA for imx35") it was
claimed that DMA works on i.MX25, i.MX31 and i.MX35 the respective
device trees don't add DMA channels. The Reference manuals of i.MX31 and
i.MX25 also don't mention the CSPI core being DMA capable. (I didn't
check the others.)

Since commit e267a5b3ec59 ("spi: spi-imx: Use dev_err_probe for failed
DMA channel requests") this results in an error message

spi_imx 43fa4000.spi: error -ENODEV: can't get the TX DMA channel!

during boot. However that isn't fatal and the driver gets loaded just
fine, just without using DMA.

[ Upstream commit df75470b317b46affbe1f5f8f006b34175be9789 ]

spi: spi-imx: imx51: revert burst length calculation back to bits_per_word

[ Upstream commit df75470b317b46affbe1f5f8f006b34175be9789 ]

The patch 15a6af94a277 ("spi: Increase imx51 ecspi burst length based
on transfer length") increased the burst length calculation in
mx51_ecspi_prepare_transfer() to be based on the transfer length.

This breaks HW CS + SPI_CS_WORD support which was added in
6e95b23a5b2d ("spi: imx: Implement support for CS_WORD") and transfers
with bits-per-word != 8, 16, 32.

SPI_CS_WORD means the CS should be toggled after each word. The
implementation in the imx-spi driver relies on the fact that the HW CS
is toggled automatically by the controller after each burst length
number of bits. Setting the burst length to the number of bits of the
_whole_ message breaks this use case.

Further the patch 15a6af94a277 ("spi: Increase imx51 ecspi burst
length based on transfer length") claims to optimize the transfers.
But even without this patch, on modern spi-imx controllers with
"dynamic_burst = true" (imx51, imx6 and newer), the transfers are
already optimized, i.e. the burst length is dynamically adjusted in
spi_imx_push() to avoid the pause between the SPI bursts. This has
been confirmed by a scope measurement on an imx6d.

Subsequent Patches tried to fix these and other problems:

- 5f66db08cbd3 ("spi: imx: Take in account bits per word instead of assuming 8-bits")
- e9b220aeacf1 ("spi: spi-imx: correctly configure burst length when using dma")
- c712c05e46c8 ("spi: imx: fix the burst length at DMA mode and CPU mode")
- cf6d79a0f576 ("spi: spi-imx: fix off-by-one in mx51 CPU mode burst length")

but the HW CS + SPI_CS_WORD use case is still broken.

To fix the problems revert the burst size calculation in
mx51_ecspi_prepare_transfer() back to the original form, before
15a6af94a277 ("spi: Increase imx51 ecspi burst length based on
transfer length") was applied.

c712c05e46c8 ("spi: imx: fix the burst length at DMA mode and CPU mode")
corrects three cases of setting the ECSPI burst length but erroneously
leaves the in-range CPU case one bit to big (in that field a value of
0 means 1 bit). The effect was that transmissions that should have been
8-bit bytes appeared as 9-bit causing failed communication with SPI
devices.

For DMA mode, the bus width of the DMA is equal to the size of data
word, so burst length should be configured as bits per word.

For CPU mode, because of the spi transfer len is in byte, so calculate
the total number of words according to spi transfer len and bits per
word, burst length should be configured as total data bits.

spi: spi-imx: correctly configure burst length when using dma

[ Upstream commit e9b220aeacf109684cce36a94fc24ed37be92b05 ]

If DMA is used, burst length should be set to the bus width of the DMA.
Otherwise, the SPI hardware will transmit/receive one word per DMA
request.
Since this issue affects both transmission and reception, it cannot be
detected with a loopback test.
