The __exit section is left out for built-in drivers, so a
'remove' callback must not be marked as such to avoid breaking when
we unbind a device at runtime. This was pointed out by kbuild:
`sprd_spi_remove' referenced in section `.data' of drivers/spi/spi-sprd.o: defined in discarded section `.exit.text' of drivers/spi/spi-sprd.o

Some combinations are simply not valid and should be rejected before
the op is passed to the SPI controller driver.
Add an spi_mem_check_op() helper and use it in spi_mem_exec_op() and
spi_mem_supports_op() to make sure the spi-mem operation is valid.

This remove the check and subsequent return of error for the case when
a SPI device requires SPI_CS_WORD and is also configured to use a GPIO
for the CS line.
Commit a134cc414e86 ("spi: always use software fallback for SPI_CS_WORD
when using cs_gio") handles this case now, so this check is no longer
necessary.

This modifies the condition for using the software fallback
implementation for SPI_CS_WORD when the SPI controller is using a GPIO
for the CS line. When using a GPIO for CS, the hardware implementation
won't work, so we just enable the software fallback globally in this
case.

Mediatek SPI driver modifies some fields (tx_buf, rx_buf, len, tx_dma,
rx_dma) of the spi_transfer* passed in when doing transfer_one and in
interrupt handler. This is somewhat unexpected, and there are some
caller (e.g. Cr50 spi driver) that reuse the spi_transfer for multiple
messages. Add a field to record how many bytes have been transferred,
and calculate the right len / buffer based on it instead.

spi: Provide SPI_CS_WORD
This provides a SPI operation mode which changes chip select after every
word, used by some devices such as ADCs and DACs.
|
|
This adds a default software implementation for the SPI_CS_WORD flag for
controllers that don't have such a feature.
The SPI_CS_WORD flag indicates that the CS line should be toggled
between each word sent, not just between each transfer. The
implementation works by using existing functions to split transfers into
one-word-sized transfers and sets the cs_change bit for each of the
new transfers.

The DaVinci SPI can use either:
- Internal chip selects (inside the SPI host)
- External chip selects (using GPIO)
- External chip selects passed in pdata
The last way of passing external chip selects through
platform data is not used in the kernel. Delete it to make
the code simpler when refactoring GPIO.

There is a logical problem in spi-gpio with host just
assigning a MOSI line and no MISO: this is interpreted
as the host cannot do RX and the host is flagged with
SPI_MASTER_NO_RX.
This is wrong: since GPIO lines can switch direction,
in 3WIRE operation the host will simply reverse the
direction of the GPIO line and start reading from it,
there is even code for doing this in the driver, but
it went unnoticed because it was tested by using a
master with 4 wires but a device using just 3 wires.
Remove the offending flag.

Pull libnvdimm memory-failure update from Dave Jiang:
"As it stands, memory_failure() gets thoroughly confused by dev_pagemap
backed mappings. The recovery code has specific enabling for several
possible page states and needs new enabling to handle poison in dax
mappings.
In order to support reliable reverse mapping of user space addresses:
1/ Add new locking in the memory_failure() rmap path to prevent races
that would typically be handled by the page lock.
2/ Since dev_pagemap pages are hidden from the page allocator and the
"compound page" accounting machinery, add a mechanism to determine
the size of the mapping that encompasses a given poisoned pfn.
3/ Given pmem errors can be repaired, change the speculatively
accessed poison protection, mce_unmap_kpfn(), to be reversible and
otherwise allow ongoing access from the kernel.
A side effect of this enabling is that MADV_HWPOISON becomes usable
for dax mappings, however the primary motivation is to allow the
system to survive userspace consumption of hardware-poison via dax.
Specifically the current behavior is:
mce: Uncorrected hardware memory error in user-access at af34214200
{1}[Hardware Error]: It has been corrected by h/w and requires no further action
mce: [Hardware Error]: Machine check events logged
{1}[Hardware Error]: event severity: corrected

Injecting memory failure for pfn 0x20cb00 at process virtual address 0x7f763dd00000
Memory failure: 0x20cb00: Killing dax-pmd:5421 due to hardware memory corruption
Memory failure: 0x20cb00: recovery action for dax page: Recovered

"A couple of late-merged changes that would be useful to get in this
merge window:
- Driver support for reset of audio complex on Meson platforms. The
audio driver went in this merge window, and these changes have been
in -next for a while (just not in our tree).
- Power management fixes for IOMMU on Rockchip platforms, getting
closer to kexec working on them, including Chromebooks.
- Another pass updating "arm,psci" -> "psci" for some properties that
have snuck in since last time it was done"
