From ac76dd0836468445e1ba4d756617d677ed58f59b Mon Sep 17 00:00:00 2001 From: Yangbo Lu Date: Thu, 19 Dec 2019 18:59:28 +0800 Subject: Add global variable sdhc_per_clk for arm/powerpc The QorIQ eSDHC controller supports two reference clocks. They are platform clock and periperhal clock. The global variable sdhc_clk has already been used for platform clock. This patch is to add another global variable sdhc_per_clk for periperhal clock, which provides higher frequency and is required to be used for SD UHS and eMMC HS200/HS400 speed modes.
