Subject: [PATCH v16 00/14] Introduce the Counter character device interface
Date: Fri, 27 Aug 2021 12:47:44 +0900 [thread overview]
Message-ID: <cover.1630031207.git.vilhelm.gray@gmail.com> (raw)
Changes in v16:
- Define magic numbers for stm32-lptimer-cnt clock polarities
- Define magic numbers for stm32-timer-cnt encoder modes
- Bump KernelVersion to 5.16 in sysfs-bus-counter ABI documentation
- Fix typos in driver API generic-counter.rst documentation file
For convenience, this patchset is also available on my personal git
repo: https://gitlab.com/vilhelmgray/iio/-/tree/counter_chrdev_v16
The patches preceding "counter: Internalize sysfs interface code" are
primarily cleanup and fixes that can be picked up and applied now to the
IIO tree if so desired. The "counter: Internalize sysfs interface code"
patch as well may be considered for pickup because it is relatively safe
and makes no changes to the userspace interface.
To summarize the main points of this patchset: there are no changes to
the existing Counter sysfs userspace interface; a Counter character
device interface is introduced that allows Counter events and associated
data to be read() by userspace; the events_configure() and
watch_validate() driver callbacks are introduced to support Counter
events; and IRQ support is added to the 104-QUAD-8 driver, serving as an
example of how to support the new Counter events functionality.
