In various cases errors may be expected, ie probe-deferral or a call to
phy_get from a driver where the use of a phy is optional.
Rather then adding all sort of complicated checks for this, and/or adding
special functions like devm_phy_get_optional, simply don't log an error,
and let deciding if get_phy returning an error really should result in a
dev_err up to the caller.

schedule_delayed_work() takes the delay in jiffies, not msecs. Fix the
caller sites in musb. This bug caused regressions with the cleanups
that went in for 3.14 (8ed1fb790ea: "usb: musb: finish suspend/reset
work independently from musb_hub_control()").

musb_port_reset() is called from musb_hub_control() which in turn holds
a spinlock, so musb_port_reset() is not allowed to call msleep().
With the asynchronous work helpers in place, this is fortunately easy to
fix by rescheduling the reset deassertion function to after the time
when the wait period is finished.
Note, however, that the MUSB_POWER_RESUME bit is only set on AM33xx
processors under rare conditions such as when to another driver
reporting an error during suspend. Hence, this didn't hit me yet in
normal operation.

High-speed USB connections revert back to full-speed signalling when
the device goes into suspend. This takes several milliseconds, and
during that time it's not possible to tell reliably whether the device
has been disconnected.
On some platforms, the Wake-On-Disconnect circuitry gets confused
during this intermediate state. It generates a false wakeup signal,
which can prevent the controller from going to sleep.
To avoid this problem, this patch adds a 5-ms delay to the
ehci_bus_suspend() routine if any ports have to switch over to
full-speed signalling. (Actually, the delay was already present for
devices using a particular kind of PHY power management; the patch
merely causes the delay to be used more widely.)

CIK parts are 128x128, older parts are 64x64.

Some hardware may not support standard 64x64 cursors. Add
a drm cap to query the cursor size from the kernel. Some examples
include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32).
This allows things like device specific ddxes to remove asics specific
logic and also allows xf86-video-modesetting to work properly with hw
cursors on this hardware. Default to 64 if the driver doesn't specify
a size.

We were already storing the bpc (bits per color) information

Commit 3dc6475 ("bcm63xx_enet: add support Broadcom BCM6345 Ethernet")
changed the ENETDMA[CS] macros such that they are no longer macros, but
actual register offset definitions. The bcm63xx_udc driver was not
updated, and as a result, causes the following build error to pop up:
CC drivers/usb/gadget/u_ether.o
drivers/usb/gadget/bcm63xx_udc.c: In function 'iudma_write':
drivers/usb/gadget/bcm63xx_udc.c:642:24: error: called object '0' is not

a function
drivers/usb/gadget/bcm63xx_udc.c:700:49: error: called object '0' is not
a function
Fix this by updating usb_dmac_{read,write}l and usb_dmas_{read,write}l to
take an extra channel argument, and use the channel width
(ENETDMA_CHAN_WIDTH) to offset the register we want to access, hence
doing again what the macro implicitely did for us.

During resume don't touch SUSPENDM/RESUME bits of POWER register
while restoring controller context. These bits might be changed
by the controller during resume operation and so will be different
than what they were during suspend.
e.g. SUSPENDM bit is set by software during USB global suspend but
automatically cleared by the controller during remote wakeup or
during resume. Setting this bit back while restoring context
causes undesired behaviour. i.e. Babble interrupt is generated
and USB is broken.

The driver was not able to manage the sensor: during probe function
and wai check, the driver stops and writes: "device name and WhoAmI mismatch."
The correct value of L3GD20H wai is 0xd7 instead of 0xd4.
Dropped support for the sensor.

Integration time of cm32181 is guessed about milliseconds.
But cm32181_read_als_it function return IIO_VAL_INT.
So fixed to return IIO_VAL_INT_PLUS_MICRO.
Next, add .write_raw_get_fmt callback function for call iio_str_to_fixpoint.
v2: cm32181_write_als_id function fixed as it was.

This patch is fixed [read/write] integration time function.
cm36651 have integration time from 1 to 640 milliseconds.
But, print more then the thousand second. when call *_integration_time attribute.
Because read_integration_time function return IIO_VAL_INT.
read integration time function is changed return IIO_VAL_INT_PLUS_MICRO;
And then .write_raw_get_fmt callback function for parse a fixed-point number from a string.
Some description is revised milliseconds unit.
v2: cm36651_write_int_time function fixed as it was.

My rework of handling of notification events (namely commit 7053aee26a35
"fsnotify: do not share events between notification groups") broke
sending of cookies with inotify events. We didn't propagate the value
passed to fsnotify() properly and passed 4 uninitialized bytes to
userspace instead (so it is also an information leak). Sadly I didn't
notice this during my testing because inotify cookies aren't used very
much and LTP inotify tests ignore them.
Fix the problem by passing the cookie value properly.

Provide services for Intel SST drivers to load SST modular firmware.

Most of the SST devices will be exposed as ACPI devices. It makes sense to
avoid duplication of the driver enumeration logic and concentrate the functionality
into a single ACPI SST enumeration file.
Idea of this loader is to parse data we get from ACPI and to be able to load
needed other SST drivers and ASoC machine driver runtime based on single
ACPI ID what BIOS gives to us.

Add support for Intel Smart Sound Technology (SST) audio DSPs.
This driver provides the low level IO, reset, boot and IRQ management
for Intel audio DSPs. These files make up the low level part of the SST
audio driver stack and will be used by many Intel SST cores like
Haswell, Broadwell and Baytrail.
SST DSPs expose a memory mapped region (shim) for config and control.
The shim layout is mostly shared without much modification across cores
and this driver provides a uniform API to access the shim and to enable
basic shim functions. It also provides functionality to abstract some shim
functions for cores with different shim features.

There are a few known (minor) problems with having the support code for both I2C
and SPI in the same module:
* We need to be extra careful to make sure to not build the driver into the
kernel if one of the subsystems is build as a module (Currently only I2C
can be build as a module).
* The module init path error handling is rather ugly. E.g. what should be
done if either the SPI or the I2C driver fails to register. Most drivers
that implement SPI and I2C in the same module currently fallback to
undefined behavior in that case. Splitting the the driver into two
modules, one for each bus, allows the registration of the other bus drive
to continue without problems if one of them fails.
This patch splits the ADAV80X driver into 3 modules. One core module that
implements the device logic, but is independent of the bus method used. And one
module for SPI and I2C each that registers the drivers and sets up the regmap
struct for the bus.

Use devm_kzalloc() to allocate the device state struct. Saves use from having to
free it manually on the error path and in the remove callback.
Now that the adav80x_bus_probe() function is only a call to
snd_soc_unregister_codec() also inline that.
