From d3eb317ea50ef763a5a1ef5ff4e2bc19498542d1 Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Tue, 12 Nov 2019 19:28:38 +0800 Subject: [PATCH] arm: drop eSDHC clock getting in mxc_get_clock() for layerscape Although layerscape platforms reuse mxc_get_clock() of i.MX platforms, eSDHC clock getting do not have to use it. It uses global data gd->arch.sdhc_clk directly in fsl_esdhc driver. Even there are more than one eSDHC controllers on SoC, they use same reference clock.
