From 5f4252ba04de9d444a72af3ebf5770f6474c4705 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Thu, 30 Nov 2023 10:11:14 +0100 Subject: [PATCH 1/2] net: phy: micrel: use devm_clk_get_optional_enabled for the rmii-ref clock While the external clock input will most likely be enabled, it's not guaranteed and clk_get_rate in some suppliers will even just return valid results when the clock is running. So use devm_clk_get_optional_enabled to retrieve and enable the clock in one go.
