This adds a new counter driver for the Texas Instruments Enhanced
Quadrature Encoder Pulse (eQEP) module.

Only very basic functionality is currently implemented - only enough to
be able to read the position. The actual device has many more features
which can be added to the driver on an as-needed basis.

It's not obvious why the change to drivers/pwm/Kconfig is needed. Can
you please motivate that in the change log?

Will do. The short version is that it is needed for power management.


Best regards
