Subject: [PATCH v3 06/15] PM / devfreq: rk3399_dmc: Drop undocumented ondemand DT props
Date:   Mon,  7 Mar 2022 16:09:36 -0800

These properties are:

* undocumented
* directly representing software properties, not hardware properties
* unused (no in-tree users, yet; this IP block has so far only been used
  in downstream kernels)

Let's just stick the values that downstream users have been using
directly in the driver and call it a day.
