audio:sst:print IPC messages using pr_info

BZ: 31581

IPC messages are exchanged between SST driver and LPE during audio
activity. These IPC messages are the main pulse of audio activity.
Printing these messages using pr_info helps us to debug issues

audio:sst:error handling during stream alloc

BZ: 32085

In rarest cases, the previous stream free may not freed by
firmware.  In such error conditions, firmware will not be
able to do stream alloc and returns stream in use error.
This causes no audio activity in a device until reboot.

If stream alloc fails due to stream in use error, free it
immediately and return the error to application.  Application
would retry again and will succeed in audio playback or capture.

mmc: sd: Handle SD3.0 cards not supporting UHS-I bus speed mode

BZ: 34834

This patch is a variant of an upstream patch. It fixed SD cannot
change high spee mode issue. Below is the original commit info:

Here is Essential conditions to indicate Version 3.00 Card
(SD_SPEC=2 and SD_SPEC3=1) :
(1) The card shall support CMD6
(2) The card shall support CMD8
(3) The card shall support CMD42
(4) User area capacity shall be up to 2GB (SDSC) or 32GB (SDHC)
User area capacity shall be more than or equal to 32GB and
up to 2TB (SDXC)
(5) Speed Class shall be supported (SDHC or SDXC)

So even if SD card doesn't support any of the newly defined
UHS-I bus speed mode, it can advertise itself as SD3.0 cards
as long as it supports all the essential conditions of
SD3.0 cards. Given this, these type of cards should atleast
run in High Speed mode @50MHZ if it supports HS.

But current initialization sequence for SD3.0 cards is
such that these non-UHS-I SD3.0 cards runs in Default
Speed mode @25MHz.

This patch makes sure that these non-UHS-I SD3.0 cards run
in High Speed Mode @50MHz.

audio: cs42l73: Fix capture widget map issues

BZ: 30339 27806 32448

The DAPM map for the capture path in the codec had a common Mic widget for both
DMIC and AMIC. Also, the multiplexing was not set up properly, as a result of
which the AMIC path was also getting enabled on DMIC recording.

Fix by providing separate DMICA, DMICB widgets for DMICs and setting up the Mux
widget properly. The Mux widget selects the path (AMIC, DMIC) based on the ALSA
mixer settings set by HAL.

This changes the ALSA mixer interface and needs a fix in the HAL layer for
recording to work properly. The HAL layer should use the new mixers provided for
recording instead of the earlier mixers.

The codec DAPM map contained different widgets like APSINL, ASPINR, ASPINM that
modify the same port settings. Having 3 widgets for the same port confuses DAPM

Additionally, replace snd_soc_write with snd_soc_update_bits which checks for

Gergely Kalman reported crashes in check_peer_redir().

It appears commit f39925dbde778 (ipv4: Cache learned redirect
information in inetpeer.) added a race, leading to possible NULL ptr
dereference.

Since we can now change dst neighbour, we should make sure a reader can
safely use a neighbour.

Add RCU protection to dst neighbour, and make sure check_peer_redir()
can be called safely by different cpus in parallel.

As neighbours are already freed after one RCU grace period, this patch
should not add typical RCU penalty (cache cold effects)

Many thanks to Gergely for providing a pretty report pointing to the
bug.

emmc_ipanic: Do not warn about harmless notifications

BZ: 23560

The notification handler currently prints error messages of
severity KERN_EMERG for any unknown notifications.  There are currently
two perfectly valid notifications that we don't need to process,
so ignore these explicitly, and lower the severity to KERN_ERR for the
notifications that we don't known about currently.  Since the driver

mt9e013: async power up sequence to decrease Lanuch2preview time

BZ: 32405

Currently power up time for mt9e013 takes about 130ms which blocks the v4l2 call

intel_scu_ipc: remove PM command synchronization

BZ: 32160

In R2 we had added serialization of IPC and PM (s0ix/lpmp3/d0ix) commands
since there were fabric errors, those issues were root caused and fixed in
SCU hence we no longer require this synchronization.

Also adding synchronization may adversly affect IPC communication, since
WatchDog keepalive is sent thru and IPC command and if s0ix is in progress the
watchdog keep alive timer may get blocked till the s0ix command gets completed
and this could take couple of seconds, by which time watch dog could get
triggerred.

Hence removing this synchronization.

usb:langwell_udc: fix pullup issue

BZ: 32720

Pullup shouldn't be connected/disconnected if dev->stopped is set which indicates interrupt
is not enabled and the controller maybe in a low power state.

Pullup should be connected if and only if the condition
dev->driver && dev->softconnected && dev->vbus_active && !dev->stopped is true.
dev->driver && dev->softconnected indicates the gadget want to connect pullup and
dev->vbus_active && !dev->stopped indicates uB is plugged in, in which state
vbus is active and controller is powered in device mode.
One related issue is in intel_mid_start_peripheral, pullup can be connected even
dev->softconnected is 0.

Solution:
1. add langwell_udc_pullup() to manage pullup connection/disconnection.
2. Check dev->stopped in langwell_udc_pullup(). If it's set, do nothing.
3. Check condition "dev->driver && dev->softconnected && dev->vbus_active && !dev->stopped"
in langwell_udc_pullup() before connecting pullup.
4. Every time when dev->driver/dev->softconnected/dev->vbus_active/dev->stopped changes,
langwell_udc_pullup should be called to connect pullup whenever is possible or disconnect
if necessary.

intel_mid_hsi.c: improving hsi_pm_runtime_get_sync and start tx synchronicity

BZ: 30613

The purpose of this patch is two fold: making the hsi_pm_runtime_get_sync()
function call synchronous to the PM management as well as start TX callback
functions.

This patch is actually waiting for the hsi_pm_resume() callback event
completion in the hsi_pm_runtime_get_sync() and start_tx() functions to ensure
that the IP is actually resumed upon the completion of these functions. Relying
solely on the wake_lock and pm_runtime_get_sync is not sufficient for this
purpose because of some race conditions between the Linux PM runtime state
machine and Android's PM state machine.

The TX path of the FFL modem protocol driver has been updated to manage the
synchronous start TX call. Since the TTY write function can be called in non
sleepable contexts, the start TX is actually called in a separate work, outside
the ffl_tty_write() function. Using the single threaded TX worqueue to manage
the start TX and stop TX is also serialiasing this management and easing the
stop TX to start TX pulse delay implementation.

This patch is also the opportunity to switch to a 3-workqueue modem protocol
implementation instead of the exisiting 5 workqueues (without considering the
start TX and stop TX workqueue), which is making much more sense.

Here is a prototype and it could work well on X86 architecture.

/proc/xxx/stack only output kernel stack call chain. We extend it to output user
space call chain With hex format.In user space, we implement a backtrace tool, it
read kernel space and user space stack call chain from /proc/xxx/stack, and converts
 the hex format into symbols., we tested it on i386/i686 and x86-64. It works well.

n_gsm.c: Enhancement of gsm_mux TX/RX buf allocate

BZ: 28510

In LEX platform, we found huge kmalloc fail if repeated gsmld open and close
that trigged by stmd(userspace) or modem reset.

LEX memory size is 512M, only the half of Medfield.

Enhancement:
1. gsm_mux buf/txframe allocation moved to gsmld_config, according to mtu/mru of cfg
2. if encoding ==0, txframe allocate one mtu; otherwise allocate double mtu
3. if allocation size less than PAGE, use kmalloc; otherwise use vmalloc

This patch is part of the solution to TX/RX buffer allocate fail.
We also need to change mtu/mru in STMD, it should matched to N1 of AT+CMUX.
N1(Maximum Frame Size) of modem is 1509 now.

atomisp: reserve ioctls to avoid ABI conflicts for customer

BZ: 27960

Customer asked us to implement 2 ioctls for debug purpose. As such
ioctls can't be merged to our tree for security purpose, we're marking
them as reserved ioctls to avoid create ABI conflicts.

lm3554: restructure i2c communications

BZ: 32196

Currently the driver uses the lm3554 registers as a storage for the values. Due
to this it communicates too often in both ways with the chip. It's a bit
suboptimal (*) and even potentialy wrong in some cases (**).

* driver uses an additional mutex for serialization and the
  read-before-write technique

** when driver had used power on or off for the chip, the storage would have
   become to the inconsistent state.

Thus this patch addresses mentioned inconveniences. It moves storege from
hardware to the struct lm3554 fields and uses only sequential writes to set a
value.

lm3554: use struct lm3554 as storage of actual values

BZ: 32196

There is no need to keep value in the hardware and sometimes it's even a bad
idea.

This patch partialy moves the storage from hardware to the struct lm3554 fields
and will be used later as well.
