This reverts stable commit baad618d078c857f99cc286ea249e9629159901f.
This commit is adding lines to spinand_write_to_cache_op, wheras the upstream
commit 868cbe2a6d that this was supposed to
backport was touching spinand_read_from_cache_op.
It causes a crash on writing OOB data by attempting to write to read-only
kernel memory.

commit bc36860211 upstream.
After each codeword NAND_FLASH_STATUS is read for possible operational
failures. But there is no DMA sync for CPU operation before reading it
and this leads to incorrect or older copy of DMA buffer in reg_read_buf.
This patch adds the DMA sync on reg_read_buf for CPU before reading it.

[ Upstream commit 1b391c7f2e ]
pm_runtime_get_sync() will increment pm usage at first and it
will resume the device later. If runtime of the device has
error or device is in inaccessible state(or other error state),
resume operation will fail. If we do not call put operation to
decrease the reference, it will result in reference leak in
the two functions(gpmi_init and gpmi_nfc_exec_op). Moreover,
this device cannot enter the idle state and always stay busy or
other non-idle state later. So we fixed it through adding
pm_runtime_put_noidle.

Merge tag 'v5.4.67' into 5.4-2.2.x-imx
This is the 5.4.67 stable release
This updates the kernel present in the NXP release imx_5.4.47_2.2.0 to the

Base stable kernel version present in the NXP BSP release is v5.4.47.
Following conflicts were recorded and resolved:

case if exception interrupt is enabled and tasklet is scheduled. Since

NXP version here.

commit c27075772d upstream.
In a previous fix, I changed the condition on which the timeout of an
IRQ is reached from:
if (!ret)
into:
if (ret && !pending)
While having a non-zero return code is usual in the Linux kernel, here
ret comes from a wait_for_completion_timeout() which returns 0 when
the waiting period is too long.
Hence, the revised condition should be:
if (!ret && !pending)
The faulty patch did not produce any error because of the !pending
condition so this change is finally purely cosmetic and does not
change the actual driver behavior.

commit 9c6c2e5cc7 upstream.
nand_release() is supposed be called after MTD device registration.
Here, only nand_scan() happened, so use nand_cleanup() instead.
There is no real Fixes tag applying here as the use of nand_release()
in this driver predates by far the introduction of nand_cleanup() in
commit d44154f969 ("mtd: nand: Provide nand_cleanup() function to free NAND related resources")
which makes this change possible. However, pointing this commit as the
culprit for backporting purposes makes sense even if this commit is not
introducing any bug.

commit c5be12e459 upstream.
Not sure nand_cleanup() is the right function to call here but in any
case it is not nand_release(). Indeed, even a comment says that
calling nand_release() is a bit of a hack as there is no MTD device to
unregister. So switch to nand_cleanup() for now and drop this
comment.

commit 1d5d08ee9b upstream.
During ONFI detection, the CRC derived from the parameter page and the
CRC supposed to be at the end of the parameter page are compared. If
they do not match, the second then the third copies of the page are
tried.
The current implementation compares the newly derived CRC with the CRC
contained in the first page only. So if this particular CRC area has
been corrupted, then the detection will fail for a wrong reason.
Fix this issue by checking the derived CRC against the right one.

[ Upstream commit 3507273d5a ]
This is done by default in the raw NAND core (nand_base.c) but was
missing in the SPI-NAND core. Without these two lines the ecc_strength
and ecc_step_size values are not exported to the user through sysfs.

commit 621a7b780b upstream.
When writing the bad block marker to the OOB area the access mode
should be set to MTD_OPS_RAW as it is done for reading the marker.
Currently this only works because req.mode is initialized to
MTD_OPS_PLACE_OOB (0) and spinand_write_to_cache_op() checks for
req.mode != MTD_OPS_AUTO_OOB.
Fix this by explicitly setting req.mode to MTD_OPS_RAW.

commit b645ad39d5 upstream.
Currently when marking a block, we use spinand_erase_op() to erase
the block before writing the marker to the OOB area. Doing so without
waiting for the operation to finish can lead to the marking failing
silently and no bad block marker being written to the flash.
In fact we don't need to do an erase at all before writing the BBM.
The ECC is disabled for raw accesses to the OOB data and we don't
need to work around any issues with chips reporting ECC errors as it
is known to be the case for raw NAND.
