It is expected for ARM and ARM64 SoC related code to go through
sub-architecture maintainers. Their addresses were therefore not
documented to push patch traffic through sub-architecture maintainers.
However when patches touch generic code, e.g. multi_v7_defconfig, the
patch might not be picked up by them and instead should go to the SoC
maintainers - Arnd and Olof.
Add a minimal maintainer's entry for SoC covering only Makefile, so it
will not appear on most of submissions (except new devicetree boards).
It will though serve as a documentation and reference for cases when
submitter does not know where to send his SoC-related patches.

The new control-message helpers include a pipe-type check which is
almost completely redundant.
Control messages are generally sent to the default pipe which always
exists and is of the correct type since its endpoint representation is
created by USB core as part of enumeration for all devices.
There is currently only one instance of a driver in the tree which use
a control endpoint other than endpoint 0 (and it does not use the new
helpers).
Drivers should be testing for the existence of their resources at probe
rather than at runtime, but to catch drivers failing to do so USB core
already does a sanity check on URB submission and triggers a WARN().
Having the same sanity check done in the helper only suppresses the
warning without allowing us to find and fix the drivers.

log_level uuid_id pipe_id comp_id;
This file may be updated by userspace applications such sof-logger,
or directly by the user during debugging process.
An unused (wildcard) pipe_id or comp_id value should be set to -1,
uuid_id is hexadecimal value, so when unused then should be set to 0.
When the file is modified, an IPC command is sent to FW with new

It is unregistered after ar934x_spi_remove() by the devres framework.
As long as it is not unregistered, SPI transfers may still be ongoing
and disabling the clock may break them. It is not possible to use
devm_spi_register_controller() in this case, so move to the non-devm

If the call to devm_spi_register_master() fails on probe of the GPIO SPI
driver, the spi_master struct is erroneously not freed:
After allocating the spi_master, its reference count is 1. The driver
unconditionally decrements the reference count on unbind using a devm
action. Before calling devm_spi_register_master(), the driver
unconditionally increments the reference count because on success,
that function will decrement the reference count on unbind. However on
failure, devm_spi_register_master() does *not* decrement the reference
count, so the spi_master is leaked.
The issue was introduced by commits 8b797490b4 ("spi: gpio: Make sure
spi_master_put() is called in every error path") and 79567c1a32 ("spi:
gpio: Use devm_spi_register_master()"), which sought to plug leaks
introduced by 9b00bc7b90 ("spi: spi-gpio: Rewrite to use GPIO
descriptors") but missed this remaining leak.
The situation was later aggravated by commit d3b0ffa1d7 ("spi: gpio:
prevent memory leak in spi_gpio_probe"), which introduced a
use-after-free because it releases a reference on the spi_master if
devm_add_action_or_reset() fails even though the function already
does that.

If the calls to devm_clk_get() or devm_ioremap_resource() fail on probe
of the Macronix SPI driver, the spi_master struct is erroneously not freed.
Fix by switching over to the new devm_spi_alloc_master() helper.

spi_geni_remove() accesses the driver's private data after calling
spi_unregister_master() even though that function releases the last
reference on the spi_master and thereby frees the private data.
Moreover, since commit 1a9e489e61 ("spi: spi-geni-qcom: Use OPP API to
set clk/perf state"), spi_geni_probe() leaks the spi_master allocation
if the calls to dev_pm_opp_set_clkname() or dev_pm_opp_of_add_table()
fail.

keeps the private data accessible until the driver has unbound and also

Following error was seen when mounting a 16MByte ubifs:
UBIFS error (ubi0:0 pid 1893): check_lpt_type.constprop.6: invalid type (15) in LPT node type
QSPI_IFR.TFRTYP was not set correctly. When data transfer is enabled
and one wants to access the serial memory through AHB in order to:
- read in the serial memory, but not a memory data, for example
a JEDEC-ID, QSPI_IFR.TFRTYP must be written to '0' (both sama5d2
and sam9x60).
- read in the serial memory, and particularly a memory data,
TFRTYP must be written to '1' (both sama5d2 and sam9x60).
- write in the serial memory, but not a memory data, for example
writing the configuration or the QSPI_SR, TFRTYP must be written
to '2' for sama5d2 and to '0' for sam9x60.
- write in the serial memory in particular to program a memory data,
TFRTYP must be written to '3' for sama5d2 and to '1' for sam9x60.
Fix the setting of the QSPI_IFR.TFRTYP field.

A recent change removed the call to send the DAPM_STREAM_STOP
event in dpcm_fe_dai_shutdown. But this causes a regression
when a PCM prepare is not paired with a hw_free. So, add
the DAPM_STREAM_STOP event back to dpcm_fe_dai_shutdown()
to fix this.
The new sequence would be:
soc_pcm_prepare()
-> SND_SOC_DAPM_STREAM_START
soc_pcm_hw_free()
-> soc_pcm_hw_free()
-> SND_SOC_DAPM_STREAM_STOP
dpcm_fe_dai_shutdown()
-> SND_SOC_DAPM_STREAM_STOP
Note that the DAPM_STREAM_STOP will be called twice but it seems
harmless.
