From cd16c57bd0d6c498d5c180d70c6f0f690e9c32de Mon Sep 17 00:00:00 2001 From: Dario Binacchi Date: Mon, 13 Apr 2020 14:36:26 +0200 Subject: [PATCH] dm: test: clk: add the test for the ccf gated clock Unlike the other clock types, in the case of the gated clock, a new driver has been developed which does not use the registering routine provided by the common clock framework. The addition of the ecspi0 clock to sandbox therefore allows testing the ccf gate clock.
