Subject: [PATCH 05/10] PM / devfreq: rk3399_dmc: Drop undocumented ondemand DT props
Date: Fri, 7 Jan 2022 15:53:15 -0800 [thread overview]
Message-ID: <20220107155215.5.I4bd77eb751d5bfce8346bfed576bcacb28e4550f@changeid> (raw)
In-Reply-To: <20220107235320.965497-1-briannorris@chromium.org>
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.
