[PATCH v2 0/4] firmware: qcom: scm: simplify code by using classes

Posted by Bartosz Golaszewski 2 months ago

There's a pattern of enabling the clocks and/or setting the bandwith
limits before performing an SCM call and reverting the above after it's
node. In all places it's done unconditionally and can be simplified by
providing appropriate classes. There are also a few places where we can
use __free() for tzmem pointers.
