  docs: counter: Include counter-chrdev kernel-doc to generic-counter.rst (2021-10-17 10:57:18 +0100)

----------------------------------------------------------------
First set of and counter subsystem new feature support for the 5.16 cycle

Most interesting element this time is the new chrdev based interface
for the counter subsystem.  Affects all drivers. Some minor precursor
patches.

Major parts:
* Bring all the sysfs attribute setup into the counter core rather than
  leaving it to individual drivers.  Docs updates accompany these changes.
* Move various definitions to a uapi header as now needed from userspace.
* Add the chardev interface + extensive documentation and example tool
* Add new ABI needed to identify indexes needed for chrdev interface
* Implement new interface for the 104-quad-8
* Follow up deals with wrong path for documentation build
* Various trivial cleanups and missing feature additions related to this
  series

I get the following error when trying to push this from my scripts:

Commit: 50cda7cc4ab1 ("counter: fix docum. build problems after filename change")
	Fixes tag: Fixes: d70e46af7531 ("counter: Internalize sysfs interface code")
	Has these problem(s):
	        - Target SHA1 does not exist

Was this caused by rebasing?

thanks,

greg k-h

Almost certainly.  I remember checking the IIO pull but guess I forgot to run
the test script on the Counter one.  Will tidy up and resend.

Thanks,

False memory on the IIO tree being fine.   Gah. I hate rebases.

Anyhow, new pull requests coming up once I've unwound this.
