System workqueues have been able to handle high level of concurrency
for a long time now and there's no reason to use dedicated workqueues
just to gain concurrency. Since aica_queue for AICA sound
driver has workitem dreamcastcard->spu_dma_work (maps to run_spu_dma)
which is involved in aica dma transfers and is not being used on a memory
reclaim path, dedicated aica_queue has been replaced with the
use of system_wq.
Unlike a dedicated per-cpu workqueue created with create_workqueue(),
system_wq allows multiple work items to overlap executions even on
the same CPU; however, a per-cpu workqueue doesn't have any CPU
locality or global ordering guarantees unless the target CPU is
explicitly specified and thus the increase of local concurrency
shouldn't make any difference.
Since the work items could be pending, flush_work() has been used in
snd_aicapcm_pcm_close() to ensure that there is no pending task while
disconnecting the driver.

The reset values for all the PCF lines are high and hence on
shutdown we should drive all the lines high in order to
bring it to the reset state.
This is actually required since PCF doesn't have a reset
line and even after warm reset (by invoking "reboot" in
prompt) the PCF lines maintains it's previous programmed
state. This becomes a problem if the boards are designed to
work with the default initial state.
DRA7XX_evm uses PCF8575 and one of the PCF output lines
feeds to MMC/SD VDD and this line should be driven high in order
for the MMC/SD to be detected. This line is modelled as
regulator and the hsmmc driver takes care of enabling and
disabling it. In the case of 'reboot', during shutdown path
as part of it's cleanup process the hsmmc driver disables
this regulator. This makes MMC *boot* not functional.
Fix it by driving all the pcf lines high.
This patch was sent long back
(https://patchwork.ozlabs.org/patch/420382/)
But there was a concern that contention might occur if the
PCF shutdown handler is invoked before the shutdown handler
of the PCF's consumers. In that case PCF shutdown handler can't
drive all the pcf lines high without knowing if the PCF
consumers are still active.
However commit 52cdbdd498 ("driver core: correct device's
shutdown order") will make sure shutdown handler of PCF's
consumers are invoked before invoking the shutdown
handler of PCF. So it should be safe to merge this now.

As kmalloc, especially when used with SLUB_DEBUG, may return a non page

This patch adds gb_timesync_to_timespec_by_svc() and
gb_timesync_to_timespec_by_interface() respectively. These routines will
convert from a given FrameTime to a ktime/timespec within an envelope of
about 17 seconds. The purpose of this routine is to enable reporting of a
FrameTime from a Module such as a Camera Module and to allow the AP to
then convert this timestamp into a Linux-native timestamp such as ktime.
This is useful and required in the v4l layer.
At 19.2MHz the accuracy of this conversion is about .3 femtoseconds per
count, which means at a 1 second offset from the reference the cumulative
error is about 1.59 nanoseconds. 1.59 nanoseconds is still less than 1
clock's worth of error @ 19.2MHz where each clock is 52.0833~ nanoseconds.
We're aiming for a maximum error rate of 30 nanoseconds which means at the
clock rate we are running at, the conversion from a FrameTime to a Linux
ktime/timespec can be plus-or-minus about 17 seconds from the reference
FrameTime/ktime pair before the routine will refuse to convert.
A realistic use-case for this routine is envisaged to be
- Greybus message received
- Some processing takes place - taking milliseconds
- Call into this routine is made
- Actual time between event in Module and conversion in AP < 1 second
- Error rate in conversion at 1.59 nanoseconds is less than 1 clock
@ 19.2MHz
This routine is not designed to allow for conversions for events with
large gaps between the event time and the current reference time for
conversion. Since FrameTime can be a very large integer we cannot convert
an arbitrarily large FrameTime to ktime, the feeling and objective here is
to make an over-provisioned envelope that in practical terms can never be
exceeded by expected use-cases. To convert longer gaps more work would have
to be done but ultimately some limit needs to be imposed and right now 0.3
femotseconds per clock on MSM8994 is both accurate and generous.
Adds:
- timesync.c::gb_timesync_frame_time_to_timespec_by_svc(
struct gb_svc *,
u64 frame_time,
struct timespec *ts)
- gb_svc is a pointer to a standard greybus SVC data structure
- frame_time is a system FrameTime.
- ts is an output parameter which represents the converted FrameTime
as a CLOCK_MONOTONIC timespec value.
- Returns 0 on success or a negative number indicating the type of
error on failure.
- timesync.c::gb_timesync_frame_time_to_timespec_by_interface(
struct gb_interface *,
u64 frame_time,
struct timespec *ts)
- gb_svc is a pointer to a standard greybus Interface data structure
- frame_time is a system FrameTime.
- ts is an output parameter which represents the converted FrameTime
as a CLOCK_MONOTONIC timespec value.
- Returns 0 on success or a negative number indicating the type of

TimeSync needs to bind into Greybus in a few places.
- core.c
To initialize its internal state and tear-down its internal state.
To schedule a timesync to a newly added Bundle after probe() completes.
- svc.c
To get access to the SVC and enable/disable timesync as well as
extracting the authoritative time from the SVC to subsequently
disseminate to other entities in the system.

This patch adds the core timesync functionality.
0. arche-platform.c/arche-apb-ctrl.c
Modifies the platform layer to hook the incoming TIME_SYNC signal up to
the timesync strobe IRQ handler. If the arche-platform driver can't
satisfy the request for the wake-detect line, it will return -EAGAIN and
the calling work-queue must reschedule the attempt to get exclusive
access to the wake-detect pin logic. A private data field is added to
the arche-platform driver to enable passing of a timesync pointer to the
ISR responsible for synchronizing time.
1. timesync.c
A new file added which contains all of the logic associated with sending
greybus commands to SVC, APBx or Interfaces to enable, disable and
disseminate timing information.
2. timesync_platform.c
Any platform/arch specific code goes into timesync_platform.c.
Originally the idea was to keep the x86 and ARM arch dependencies in a
timesync_platform_arch.c file - however with further refinement that's
currently not necessary however just-in-case it becomes necessary to
resuscitate arch or platform specific methods for accessing timer
resources that access shouldn't be part of the core timesync.c logic and
so for the moment we access these timer resources through a thin access
layer in timesync_platform.c. Expect this to go away long term ideally.

Reporting DISCONNECT event immediately on module removal causes

Ideally, it should report 'MODULE_NOT_READY' on module plug-out and
DISCONNECT after resource cleanup. This would involve changes in GB
Audio manager and HAL layer.
Since we already have a plan to remove GB Audio manager, I'm making this
change in GB codec driver to avoid any race condition. Also, codec
