Subject: [PATCH] clk: tests: Add test suites description
|
|
|
|
We start to have a few test suites, and we'll add more, so it will get
|
|
pretty confusing to figure out what is supposed to be tested in what
|
|
suite.
|
|
|
|
Let's add some comments to explain what setup they create, and what we
|
|
should be testing in every suite.
