Third set of IIO new device support cleanups and fixes for the 5.5 cycle.
New device support
* ad5446
- Support the ad5600 DAC (id only needed).
* ad7292 ADC DAC etc
- New driver plus dt-bindings.
* veml6030 ambient light sensor
- New driver plus dt-bindings and sysfs docs.
Features
* mpu6050
- Explicit VDD control.
* stm32-adc
- Allow limiting of max clock frequency from devicetree to ensure it's
suitable for external circuitry.
yaml binding conversions
* ltc1660
* mcp3911
Fixes
* adis16480
- Fix wrong scale factors.
- Fix debugfs reg access by providing the callback.
* cros_ec_baro
- Fixing missing mask entry to make available sample frequencies visible
in sysfs.
* st_lsm6dsx
- Explicitly handle different ODR table sizes.
- Handle restrictions between slave ODR and accel ODR when
both are enabled.
- Allow ODR to be expressed more accurately by using miliHz.
* tools
- Fix an issue with parallel builds.
Cleanups and warning fixes
* adis16136, adis16400, adis16460, adis-lib
- Change some checks on return values to be for 0 rather than strictly
negative. Avoids some fiddly issues with the compiler concluding some
variables are initialized due to a mixture of error checks.
- Assign values only on success of 'read' operations - avoiding any
chance the compiler will falsly suggest they might be used uninitialized.
- Whitespace and simlar cleanups.
* aspeed adc
- devm_platfom_ioremap_resource to reduce boilerplate.
* bcm-iproc-adc
- Stray semicolon removal.
* cc10001
- devm_platfom_ioremap_resource to reduce boilerplate.
* dln2-adc
- Reorganise the buffered mode setup and tear down. Part of moving towards
being able to refactor this area of the IIO core.
* hdc100x
- Reorganise the buffered mode setup and tear down.
* ingenic-adc
- devm_platfom_ioremap_resource to reduce boilerplate.

Intel Wired LAN Driver Fixes 2019-11-08
This series contains fixes to igb, igc, ixgbe, i40e, iavf and ice
drivers.
Colin Ian King fixes a potentially wrap-around counter in a for-loop.
Nick fixes the default ITR values for the iavf driver to 50 usecs
interval.
Arkadiusz fixes 'ethtool -m' for X722 devices where the correct value
cannot be obtained from the firmware, so add X722 to the check to ensure
the wrong value is not returned.
Jake fixes igb and igc drivers in their implementation of launch time
support by declaring skb->tstamp value as ktime_t instead of s64.
Magnus fixes ixgbe and i40e where the need_wakeup flag for transmit may
not be set for AF_XDP sockets that are only used to send packets.

ixgbe: need_wakeup flag might not be set for Tx
The need_wakeup flag for Tx might not be set for AF_XDP sockets that
are only used to send packets. This happens if there is at least one
outstanding packet that has not been completed by the hardware and we
get that corresponding completion (which will not generate an
interrupt since interrupts are disabled in the napi poll loop) between
the time we stopped processing the Tx completions and interrupts are
enabled again. In this case, the need_wakeup flag will have been
cleared at the end of the Tx completion processing as we believe we
will get an interrupt from the outstanding completion at a later point
in time. But if this completion interrupt occurs before interrupts
are enable, we lose it and should at that point really have set the
need_wakeup flag since there are no more outstanding completions that
can generate an interrupt to continue the processing. When this
happens, user space will see a Tx queue need_wakeup of 0 and skip
issuing a syscall, which means will never get into the Tx processing
again and we have a deadlock.
This patch introduces a quick fix for this issue by just setting the
need_wakeup flag for Tx to 1 all the time. I am working on a proper
fix for this that will toggle the flag appropriately, but it is more
challenging than I anticipated and I am afraid that this patch will
not be completed before the merge window closes, therefore this easier
fix for now. This fix has a negative performance impact in the range
of 0% to 4%. Towards the higher end of the scale if you have driver
and application on the same core and issue a lot of packets, and
towards no negative impact if you use two cores, lower transmission
speeds and/or a workload that also receives packets.

igb/igc: use ktime accessors for skb->tstamp
When implementing launch time support in the igb and igc drivers, the
skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t
value.
Although ktime_t is typedef'd to s64 it wasn't always, and the kernel
provides accessors for ktime_t values.
Use the ktime_to_timespec64 and ktime_set accessors instead of directly
assuming that the variable is always an s64.
This improves portability if the code is ever moved to another kernel
version, or if the definition of ktime_t ever changes again in the
future.

iavf: initialize ITRN registers with correct values
Since commit 92418fb14750 ("i40e/i40evf: Use usec value instead of reg
value for ITR defines") the driver tracks the interrupt throttling
intervals in single usec units, although the actual ITRN registers are
programmed in 2 usec units. Most register programming flows in the driver
correctly handle the conversion, although it is currently not applied when
the registers are initialized to their default values. Most of the time
this doesn't present a problem since the default values are usually
immediately overwritten through the standard adaptive throttling mechanism,
or updated manually by the user, but if adaptive throttling is disabled and
the interval values are left alone then the incorrect value will persist.
Since the intended default interval of 50 usecs (vs. 100 usecs as
programmed) performs better for most traffic workloads, this can lead to
performance regressions.
This patch adds the correct conversion when writing the initial values to
the ITRN registers.

there is a potential wrap-around of counter i back to zero if
