From 7d4901d96584764388568d68412b4b536312a8fb Mon Sep 17 00:00:00 2001 From: Will McVicker Date: Thu, 14 Oct 2021 19:53:46 +0000 Subject: [PATCH] clk: samsung: exynos5433: update apollo and atlas clock probing Use the samsung common clk driver to initialize the apollo and atlas clocks. This removes their custom init functions and uses the samsung_cmu_register_one() instead.
