Thanks, Jonathan Shinji, If you reimplement this driver to use the new Generic Counter API, I can pick it up and include it with my next patchset submission.

[PATCH 0/2] Add Updown Counter support for Milbeaut M10V SoC
This is a series of patch which adds Updown Counter support on Milbeaut M10V SoC. The Updown Counter counts input pulse signal from external quadrature encoder. It also has input pulse signal counter function.
