Hello, Initial versions of the patchset intended to introduce the use of iio_hwmon for Vybrid SoC's. Currently the iio_hwmon driver has two users and as per the binding documentation, the node names use the underscore. Use of hypen in device tree node names is acceptable, however currently the hwmon core code rejects it due to perhaps user space not liking the hypen and getting confused. As per Guenter Roeck's suggestion, the first patch looks for a hypen and replaces it with a underscore in the probe call of iio_hwmon driver before calling hwmon_device_register_with_groups for registration. Any users of iio_hwmon driver can now use hypen in the node name. As per Shawn's suggestion, the existing users have been changed to use the hypen instead of the underscore and the iio-bindings document updated. Third patch introduces the usage for Vybrid itself. Patchset is based on top of shawn's for-next branch. Feedbacks and comments most welcome. Thank you for feedbacks. @Guenter I hope I understood and implemented correctly what you had in mind.
