Jonathan writes:
Second set of IIO new drivers, functionality and cleanups for the 4.5 cycle.
The big one here is the configfs support which has been a long time in the
works but should allow for cleaner ways to do instantiation of those elements
of IIO that aren't directly connected to specific hardware. Lots of cool new
stuff we can use this for in the works!
New core stuff (basically all configfs support related)
* Configfs support
- Core support (was waiting for a configfs patch that went in around 4.4rc2)
- A little fixlet to add a configfs.h to contain a reference to the
configfs_subsystem structure.
* Some infrastructure to simplify handling of software based triggers
(i.e. ones with no actual hardware associated with them)
* A high resolution timer based trigger. This has been around for years
but until the configfs support was ready we didn't have a sensible way
of instantiating instances of it (the method used for the sysfs_trigger
has never been really satisfactory)
New Device Support
* AMS iAQ Volatile Organic Compounds sensor support.
* Freescale imx7d ADC driver
* Maxim MAX30100 oximeter driver (note that for these devices most of the
smart stuff will be in userspace - effectively they are just light sensors
with some interesting led synchronization as far as the kernel is concerned).
* Microchip mcp3421 support added to the mcp3422 driver.
* TI adc124s021 support added to the adc128s052 driver.
* TI ina219, inda226 power monitors. Note that there is an existing hwmon driver
for these parts, the usecase is somewhat different so it is unclear at this
point if the hwmon driver will eventually be replaced by a bridge from
this driver. In the meantime the Kconfig dependencies should prevent both
from being built.
New driver functionality
* us8152d power management support.
Cleanups, fixups
* Use list_for_each_entry_safe instead of list_for_each_safe with the entry
bit coded longhand.
* Select IRQ_WORK for IIO_DUMMY_EVGEN. This is a fix that somehow got lost
when the driver was moved so lets do it again.
* st-accel - drop an unused define.
* vz89x, lidar - optimize i2c transactions by using a single i2c tranfers
instead of multiple calls where supported (fall back to smbus calls as
before if not).
* Use dev_get_platdata() in staging drivers: tsl2x7x, adcs and frequency
drivers instead of direct access to the structure element.

Kishon writes:
phy: for 4.5
*) new PHY driver for hi6220 usb and rcar gen3 usb2
*) deprecate phy-omap-control driver. phy-omap-control driver was added
when there was no proper infrastructure for doing control module
initialization. The phy-omap-control driver is not an 'actual' PHY
driver and it was just a hack to do PHY related control module
initialization. Now with SYSCON framework in the kernel, control
module setttings can be done using APIs provided by syscon.
*) usbphy-internal pll creates the needed 480MHz and is also a
supply-clock back to the core clock-controller in Rockchip SoCs.
This is now modeled as a real clock.
*) calibrate mt65xx usb3 PHY for better eye diagram and receiver
sensitivity.
*) Miscellaneous cleanups.

usb: patches for v4.5
A ton of improvements to dwc2 have been made. The
driver should be a lot more stable on v4.5 then ever
before.
Our good old dwc3 got a few cleanups and misc fixes
and also added support to Xilinx's integration of
this IP.
Yoshihiro Shimoda gives us support for a new USB3
peripheral controller from Renesas.
Other than these, the usual misc fixes all over the
place.

Since gpiochip .get() callback may return a negative error value, it
strictly limits the range of possible non-error returned values to
a subset of [30:0] bitmask, however on practice on success all
gpiochip drivers return either 0 for low signal or 1 for high signal,
this is assured by "gpio: *: Be sure to clamp return value" series of
changes. To avoid any confusion, misinterpretation and potential
errors while developing gpiochip drivers in future convert this
implicit assumption to a mandatory rule.
For output signals with unknown output signal state gpiochip drivers
should return a negative error instead of 0.

NCM buffer sizes are negotiated with the device independently of
the network device MTU. The RX buffers are allocated by the
usbnet framework based on the rx_urb_size value set by cdc_ncm. A
single RX buffer can hold a number of MTU sized packets.
The default usbnet change_mtu ndo only modifies rx_urb_size if it
is equal to hard_mtu. And the cdc_ncm driver will set rx_urb_size
and hard_mtu independently of each other, based on dwNtbInMaxSize
and dwNtbOutMaxSize respectively. It was therefore assumed that
usbnet_change_mtu() would never touch rx_urb_size. This failed to
consider the case where dwNtbInMaxSize and dwNtbOutMaxSize happens
to be equal.
Fix by implementing an NCM specific change_mtu ndo, modifying the
netdev MTU without touching the buffer size settings.

Some clocks need to be enabled to accept rate changes. This patch adds a
new flag CLK_SET_RATE_UNGATE that lets clk_change_rate enable the clock
before trying to change the rate and disable it again afterwards.
This of course doesn't effect clocks that are already running at that
point, as their refcount will only temporarily increase.

TRACE_EVENT_FN can't be used in some circumstances
like invoking trace functions from offlined CPU due
to RCU usage.
This patch adds the TRACE_EVENT_FN_COND macro
to make such trace points conditional.

Currently perf has its own list function within the ftrace infrastructure
that seems to be used only to allow for it to have per-cpu disabling as well
as a check to make sure that it's not called while RCU is not watching. It
uses something called the "control_ops" which is used to iterate over ops
under it with the control_list_func().
The problem is that this control_ops and control_list_func unnecessarily
complicates the code. By replacing FTRACE_OPS_FL_CONTROL with two new flags
(FTRACE_OPS_FL_RCU and FTRACE_OPS_FL_PER_CPU) we can remove all the code
that is special with the control ops and add the needed checks within the
generic ftrace_list_func().

Add a function svc_age_temp_xprts_now() to close temporary transports
whose xpt_local matches the address passed in server_addr immediately
instead of waiting for them to be closed by the timer function.
The function is intended to be used by notifier_blocks that will be
added to nfsd and lockd that will run when an ip address is deleted.
This will eliminate the ACK storms and client hangs that occur in
HA-NFS configurations where nfsd & lockd is left running on the cluster
nodes all the time and the NFS 'service' is migrated back and forth
within a short timeframe.

ASoC: Updates for v4.5
This is quite a busy release on the driver front with a lot of new
drivers being added but comparatively quiet on the core side with only
one big change going in and that a fairly straightforward refactoring.
- Conversion of the array of DAI links to a list by Mengdong Lin,
supporting dynamically adding and removing DAI links.
- Some more fixes for the topology code, though it is still not final
and ready for enabling in production. We really need to get to the
point where that can be done.
- A pile of changes for Intel SkyLake drivers which hopefully deliver
some useful initial functionality for systems with this chipset,
though there is more work still to come.
- New drivers for a number of Imagination Technologies IPs.
- Lots of new features and cleanups for the Renesas drivers.
- ANC support for WM5110.
- New driver for Atmel class D speaker drivers.
- New drivers for Cirrus CS47L24 and WM1831.
- New driver for Dialog DA7128.
- New drivers for Realtek RT5659 and RT56156.
- New driver for Rockchip RK3036.
- New driver for TI PC3168A

When working with the compressed framework occasionally vendors will
use esoteric internal audio formats. For such formats it doesn't really
make sense to add an new define to the kernel as their use is not
sufficiently general.
This patch adds a new define SND_AUDIOCODEC_BESPOKE that vendors can use
in such situations.
