[PATCH v10 00/18] Introduce the Counter subsystem

Changes in v10:
- Fix minor typographical errors in documentation
- Merge the FlexTimer Module Quadrature decoder counter driver patches

This revision is functionally identical to the last; changes in this
version were made to fix minor typos in the documentation files and also
to pull in the new FTM quadrature decoder counter driver.

The Generic Counter API has been and is still in a feature freeze until
it is merged into the mainline. The following features will be
investigated after the merge: interrupt support for counter devices, and
a character device interface for low-latency applications.

Benjamin Gaignard (2):
counter: Add STM32 Timer quadrature encoder
dt-bindings: counter: Document stm32 quadrature encoder

Fabrice Gasnier (2):
counter: stm32-lptimer: add counter device
dt-bindings: counter: Adjust dt-bindings for STM32 lptimer move

Patrick Havelange (7):
include/fsl: add common FlexTimer #defines in a separate header.
drivers/pwm: pwm-fsl-ftm: use common header for FlexTimer #defines
drivers/clocksource: timer-fsl-ftm: use common header for FlexTimer
#defines
dt-bindings: counter: ftm-quaddec
counter: add FlexTimer Module Quadrature decoder counter driver
counter: ftm-quaddec: Documentation: Add specific counter sysfs
documentation
LS1021A: dtsi: add ftm quad decoder entries

William Breathitt Gray (7):
counter: Introduce the Generic Counter interface
counter: Documentation: Add Generic Counter sysfs documentation
docs: Add Generic Counter interface documentation
iio: 104-quad-8: Update license boilerplate
counter: 104-quad-8: Add Generic Counter interface support
counter: 104-quad-8: Documentation: Add Generic Counter sysfs
documentation
iio: counter: Add deprecation markings for IIO Counter attributes
