The new Generic Counter interface sysfs attributes are intended to
expose the same functionality and data available via the existing

counter: Introduce the Generic Counter interface
This patch introduces the Generic Counter interface for supporting
counter devices.
In the context of the Generic Counter interface, a counter is defined as
a device that reports one or more "counts" based on the state changes of
one or more "signals" as evaluated by a defined "count function."
Driver callbacks should be provided to communicate with the device: to
read and write various Signals and Counts, and to set and get the
"action mode" and "count function" for various Synapses and Counts
respectively.
To support a counter device, a driver must first allocate the available
Counter Signals via counter_signal structures. These Signals should
be stored as an array and set to the signals array member of an
allocated counter_device structure before the Counter is registered to
the system.
Counter Counts may be allocated via counter_count structures, and
respective Counter Signal associations (Synapses) made via
counter_synapse structures. Associated counter_synapse structures are
stored as an array and set to the the synapses array member of the
respective counter_count structure. These counter_count structures are
set to the counts array member of an allocated counter_device structure
before the Counter is registered to the system.
A counter device is registered to the system by passing the respective
initialized counter_device structure to the counter_register function;
similarly, the counter_unregister function unregisters the respective
Counter. The devm_counter_register and devm_counter_unregister functions
serve as device memory-managed versions of the counter_register and
counter_unregister functions respectively.

iio: gyro: add core driver for fxas21002c
Add core support for the NXP fxas21002c Tri-axis gyroscope,
using the iio subsystem. It supports PM operations, axis reading,
temperature, scale factor of the axis, high pass and low pass
filtering, and sampling frequency selection.
It will have extras modules to support the communication over i2c and
spi.

staging: kpc2000: add initial set of Daktronics drivers
These drivers have been outside of the kernel tree since the 2.x days,
and it's time to bring them into the tree so they can get properly
cleaned up.
This first dump of drivers is based on a tarball Matt gave to me, minus
an odd "dma" driver that I could not get to build at all. I renamed a
few files, added the proper SPDX lines to it, added Kconfig entries and
tied it into the kernel build. I also fixed up a number of initial
obvious kernel build warnings, but left the odd bitfield warning that
gcc is spitting out, as I'm not quite sure what to do about that.
There's loads of low-hanging coding style cleanups in here for people to
start attacking, as well as the more obvious logic and api cleanups as
well.
