[PATCH v8 00/13] add ecspi ERR009165 for i.mx6/7 soc family

[PATCH v8 00/13] add ecspi ERR009165 for i.mx6/7 soc family

[Robin Gong]

There is ecspi ERR009165 on i.mx6/7 soc family, which cause FIFO
transfer to be send twice in DMA mode. Please get more information from:
https://www.nxp.com/docs/en/errata/IMX6DQCE.pdf. The workaround is adding
new sdma ram script which works in XCH  mode as PIO inside sdma instead
of SMC mode, meanwhile, 'TX_THRESHOLD' should be 0. The issue should be
exist on all legacy i.mx6/7 soc family before i.mx6ul.
NXP fix this design issue from i.mx6ul, so newer chips including i.mx6ul/
6ull/6sll do not need this workaroud anymore. All other i.mx6/7/8 chips
still need this workaroud. This patch set add new 'fsl,imx6ul-ecspi'
for ecspi driver and 'ecspi_fixed' in sdma driver to choose if need errata
or not.
The first two reverted patches should be the same issue, though, it
seems 'fixed' by changing to other shp script. Hope Sean or Sascha could
have the chance to test this patch set if could fix their issues.
Besides, enable sdma support for i.mx8mm/8mq and fix ecspi1 not work
on i.mx8mm because the event id is zero.

PS:
   Please get sdma firmware from below linux-firmware and copy it to your
local rootfs /lib/firmware/imx/sdma.
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git/tree/imx/sdma

v2:
  1.Add commit log for reverted patches.
  2.Add comment for 'ecspi_fixed' in sdma driver.
  3.Add 'fsl,imx6sll-ecspi' compatible instead of 'fsl,imx6ul-ecspi'
    rather than remove.
v3:
  1.Confirm with design team make sure ERR009165 fixed on i.mx6ul/i.mx6ull
    /i.mx6sll, not fixed on i.mx8m/8mm and other i.mx6/7 legacy chips.
    Correct dts related dts patch in v2.
  2.Clean eratta information in binding doc and new 'tx_glitch_fixed' flag
    in spi-imx driver to state ERR009165 fixed or not.
  3.Enlarge burst size to fifo size for tx since tx_wml set to 0 in the
    errata workaroud, thus improve performance as possible.
v4:
  1.Add Ack tag from Mark and Vinod
  2.Remove checking 'event_id1' zero as 'event_id0'.
v5:
  1.Add the last patch for compatible with the current uart driver which
    using rom script, so both uart ram script and rom script supported
    in latest firmware, by default uart rom script used. UART driver
    will be broken without this patch.
v6:
  1.Resend after rebase the latest next branch.
  2.Remove below No.13~No.15 patches of v5 because they were mergered.
  	ARM: dts: imx6ul: add dma support on ecspi
  	ARM: dts: imx6sll: correct sdma compatible
  	arm64: defconfig: Enable SDMA on i.mx8mq/8mm
  3.Revert "dmaengine: imx-sdma: fix context cache" since
    'context_loaded' removed.
v7:
  1.Put the last patch 13/13 'Revert "dmaengine: imx-sdma: fix context
    cache"' to the ahead of 03/13 'Revert "dmaengine: imx-sdma: refine
    to load context only once" so that no building waring during comes out
    during bisect.
  2.Address Sascha's comments, including eliminating any i.mx6sx in this
    series, adding new 'is_imx6ul_ecspi()' instead imx in imx51 and taking
    care SMC bit for PIO.
  3.Add back missing 'Reviewed-by' tag on 08/15(v5):09/13(v7)
   'spi: imx: add new i.mx6ul compatible name in binding doc'
v8:
  1.remove 0003-Revert-dmaengine-imx-sdma-fix-context-cache.patch and merge
    it into 04/13 of v7
  2.add 0005-spi-imx-fallback-to-PIO-if-dma-setup-failure.patch for no any
    ecspi function broken even if sdma firmware not updated.
  3.merge 'tx.dst_maxburst' changes in the two continous patches into one
    patch to avoid confusion.
  4.fix typo 'duplicated'.

[PATCH v8 01/13] Revert "ARM: dts: imx6q: Use correct SDMA script for SPI5 core"

[Robin Gong]

  There are two ways for SDMA accessing SPBA devices: one is SDMA->AIPS
->SPBA(masterA port), another is SDMA->SPBA(masterC port). Please refer
to the 'Figure 58-1. i.MX 6Dual/6Quad SPBA connectivity' of i.mx6DQ
Reference Manual. SDMA provide the corresponding app_2_mcu/mcu_2_app and
shp_2_mcu/mcu_2_shp script for such two options. So both AIPS and SPBA
scripts should keep the same behaviour, the issue only caught in AIPS
script sounds not solide.
  The issue is more likely as the ecspi errata
ERR009165(http://www.nxp.com/docs/en/errata/IMX6DQCE.pdf):
eCSPI: TXFIFO empty flag glitch can cause the current FIFO transfer to
       be sent twice
So revert commit 'df07101e1c4a' firstly.

This reverts commit ad0d92d7ba6aecbe2705907c38ff8d8be4da1e9c, because
in spi-imx case, burst length may be changed dynamically.

ERR009165 fixed on i.mx6ul/6ull/6sll. All other i.mx6/7 and
i.mx8m/8mm still need this errata. Please refer to nxp official

[PATCH v8 12/13] dmaengine: imx-sdma: fix ecspi1 rx dma not work on i.mx8mm

[Robin Gong]

Because the number of ecspi1 rx event on i.mx8mm is 0, the condition
check ignore such special case without dma channel enabled, which caused
ecspi1 rx works failed. Actually, no need to check event_id0/event_id1
and replace checking 'event_id1' with 'DMA_DEV_TO_DEV', so that configure
event_id1 only in case DEV_TO_DEV.

[PATCH v8 13/13] dmaengine: imx-sdma: add uart rom script

[Robin Gong]

For the compatibility of NXP internal legacy kernel before 4.19 which
is based on uart ram script and upstreaming kernel based on uart rom
script, add both uart ram/rom script in latest sdma firmware. By default
uart rom script used.
Besides, add two multi-fifo scripts for SAI/PDM on i.mx8m/8mm and add
back qspi script miss for v4(i.mx7d/8m/8mm family, but v3 is for i.mx6).

rom script:
        uart_2_mcu_addr
	uartsh_2_mcu_addr /* through spba bus */
am script:
	uart_2_mcu_ram_addr
	uartsh_2_mcu_ram_addr /* through spba bus */

Please get latest sdma firmware from the below and put them into the path
(/lib/firmware/imx/sdma/):
https://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

[1/1] spi: imx: fallback to PIO if dma setup failure
      commit: bcd8e7761ec9c128b9102b0833d9c7052ae2dbcf

All being well this means that it will be integrated into the linux-next
tree (usually sometime in the next 24 hours) and sent to Linus during
the next merge window (or sooner if it is a bug fix), however if
problems are discovered then the patch may be dropped or reverted.

You may get further e-mails resulting from automated or manual testing
and review of the tree, please engage with people reporting problems and
send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they
should be sent as incremental updates against current git, existing
patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying
to this mail.

Thanks,
Mark

Hello Robin,

we have tried out this series, and there seems to be an issue with the
PIO fallback. We are testing on an i.MX6Q board, and our kernel is a
mostly-unmodified 5.4, on which we backported all SDMA patches from
next-20200602 (imx-sdma.c is identical to next-20200602 version), and 
then applied this whole series.

We build the SDMA driver as a kernel module, which is loaded by udev,
so the root filesystem is ready and the SDMA firmware can be loaded.
The behaviour we're seeing is the following:

1. As long as the SDMA driver is not loaded, initializing spi_imx will
be deferred
2. imx_sdma is loaded. The SDMA firmware is not yet loaded at this
point
3. spi_imx is initialized and an SPI-NOR flash is probed. To load the
BFPT, the driver will attempt to use DMA; this will fail with EINVAL as
long as the SDMA firmware is not ready, so the fallback to PIO happens
(4. SDMA firmware is ready, subsequent SPI transfers use DMA)

The problem happens in step 3: Whenever the driver falls back to PIO,
the received data is corrupt. The behaviour is specific to the
fallback: When I disable DMA completely via spi_imx.use_dma, or when
the timing is lucky and the SDMA firmware gets loaded before the flash
is probed, no corruption can be observed.

Kind regards,
Matthias

I have attached the following log files:
- pio.log: DMA disabled via module parameter
- dma.log: "lucky" timing, SDMA firmware loaded before SPI-NOR probe
- fallback.log: DMA->PIO fallback

The logs include some additional log messages:
- Return value of spi_imx_dma_transfer() before PIO fallback
- SPI-NOR SFPT dump

It can be seen that the BFPT data is identical in pio.log and dma.log,
and differs almost completely in fallback.log. The corrupted data seems
to be random, or uninitialized memory; it differs with every boot.

Kind regards,
Matthias

Subject: [PATCH v9 06/14] spi: imx: add dma_sync_sg_for_device after fallback
 from dma

In case dma transfer failed and fallback to pio, tx_buf/rx_buf need to be
taken care cache since they have already been  mapped by dma_map_sg() in
spi.c.
