The USB core and sysfs will attempt to enumerate certain parameters
which are unsupported by the au0828 - causing inconsistent behavior
and sometimes causing the chip to reset. Avoid making these calls.
This problem manifested as intermittent cases where the au8522 would
be reset on analog video startup, in particular when starting up ALSA
audio streaming in parallel - the sysfs entries created by
snd-usb-audio on streaming startup would result in unsupported control
messages being sent during tuning which would put the chip into an
unknown state.

Some LEDs can be related to a specific device(s) described in the DT.
This property allows specifying such relations. E.g. USB LED should
usually be used to indicate some USB port(s) state.
Please note this binding is designed to be generic and not influenced by
any operating system design. Linux developers may find "trigger" part a
bit confusing since in Linux triggers are separated drivers. It
shouldn't define the binding though (we shouldn't add an extra level of
indirection).

Driver for ACPI UCSI interface method. This driver replaces

UCSI - USB Type-C Connector System Software Interface - is a
specification that defines set of registers and data
structures for controlling the USB Type-C ports. It's
designed for systems where an embedded controller (EC) is in
charge of the USB Type-C PHY or USB Power Delivery
controller. It is designed for systems with EC, but it is
not limited to them, and for example some USB Power Delivery
controllers will use it as their direct control interface.
With UCSI the EC (or USB PD controller) acts as the port
manager, implementing all USB Type-C and Power Delivery state
machines. The OS can use the interfaces for reading the
status of the ports and controlling basic operations like
role swapping.
The UCSI specification highlights the fact that it does not
define the interface method (PCI/I2C/ACPI/etc.).
Therefore the driver is implemented as library and every
supported interface method needs its own driver. Driver for
ACPI is provided in separate patch following this one.
The initial driver includes support for all required
features from UCSI specification version 1.0 (getting
connector capabilities and status, and support for power and
data role swapping), but none of the optional UCSI features
(alternate modes, power source capabilities, and cable
capabilities).

Instead of requesting the DMA channel in tusb_omap_dma_allocate() do it
when the controller is created and in runtime work from the DMA channel
pool.
This change is needed for the DMAengine conversion of the driver since the
tusb_omap_dma_allocate() is called in interrupt context which might lead
to lock within the DMAengine API when requesting channel.

When the port_window support was verified it was done on setup where only
the MEM_TO_DEV direction was enabled. This got un-noticed and thus only
this direction worked.
Now that I have managed to get a setup to verify both direction it turned
out that the setup was incorrect:
omap_desc members are settings for the slave port while the omap_sg members
apply to the memory side of the sDMA setup.

Stack guard page is a useful feature to reduce a risk of stack smashing
into a different mapping. We have been using a single page gap which
is sufficient to prevent having stack adjacent to a different mapping.
But this seems to be insufficient in the light of the stack usage in
userspace. E.g. glibc uses as large as 64kB alloca() in many commonly
used functions. Others use constructs liks gid_t buffer[NGROUPS_MAX]
which is 256kB or stack strings with MAX_ARG_STRLEN.
This will become especially dangerous for suid binaries and the default
no limit for the stack size limit because those applications can be
tricked to consume a large portion of the stack and a single glibc call
could jump over the guard page. These attacks are not theoretical,
unfortunatelly.
Make those attacks less probable by increasing the stack guard gap
to 1MB (on systems with 4k pages; but make it depend on the page size
because systems with larger base pages might cap stack allocations in
the PAGE_SIZE units) which should cover larger alloca() and VLA stack
allocations. It is obviously not a full fix because the problem is
somehow inherent, but it should reduce attack space a lot.
One could argue that the gap size should be configurable from userspace,
but that can be done later when somebody finds that the new 1MB is wrong
for some special case applications. For now, add a kernel command line
option (stack_guard_gap) to specify the stack gap size (in page units).
Implementation wise, first delete all the old code for stack guard page:
because although we could get away with accounting one extra page in a
stack vma, accounting a larger gap can break userspace - case in point,
a program run with "ulimit -S -v 20000" failed when the 1MB gap was
counted for RLIMIT_AS; similar problems could come with RLIMIT_MLOCK
and strict non-overcommit mode.
Instead of keeping gap inside the stack vma, maintain the stack guard
gap as a gap between vmas: using vm_start_gap() in place of vm_start
(or vm_end_gap() in place of vm_end if VM_GROWSUP) in just those few
places which need to respect the gap - mainly arch_get_unmapped_area(),
and and the vma tree's subtree_gap support for that.

This patch adds a new function 'f_uac1'
(f_uac1 with virtual "ALSA card") that
uses recently created u_audio API. Comparing
to legacy f_uac1 function implementation it
doesn't require any real Audio codec to be
present on the device. In f_uac1 audio
streams are simply sinked to and sourced
from a virtual ALSA sound card created
using u_audio API.
Legacy f_uac1 approach is to write audio
samples directly to existing ALSA sound
card
f_uac1 approach is more generic/flexible
one - create an ALSA sound card that
represents USB Audio function and allows to
be used by userspace application that
may choose to do whatever it wants with the
data received from the USB Host and choose
to provide whatever it wants as audio data
to the USB Host.
f_uac1 also has capture support (gadget->host)
thanks to easy implementation via u_audio.
By default, capture interface has 48000kHz/2ch
configuration, same as playback channel has.
f_uac1 descriptors naming convention
uses f_uac2 driver naming convention that
makes it more common and meaningful.
Comparing to f_uac1_legacy, the f_uac1 doesn't
have volume/mute functionality. This is because
the f_uac1 volume/mute feature unit was dummy
implementation since that driver creation (2009)
and never had any real volume control or mute
functionality, so there is no any difference
here.
Since f_uac1 functionality, exposed
interface to userspace (virtual ALSA card),
input parameters are so different comparing
to f_uac1_legacy, that there is no any
reason to keep them in the same file/module,
and separate function was created.
g_audio can be built using one of existing
UAC functions (f_uac1, f_uac1_legacy or f_uac2)
