From 6e3dc127545247f123de063a6a101960e3eb2ccd Mon Sep 17 00:00:00 2001 From: =?utf8?q?Beno=C3=AEt=20Th=C3=A9baudeau?= Date: Thu, 27 Sep 2012 10:26:02 +0000 Subject: [PATCH] mx35: Fix eSDHC clocks MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Each eSDHC instance has a dedicated clock. gd->sdhc_clk must also be set accordingly. This is good for the case only a single SDHC instance is used (initialization made with fsl_esdhc_mmc_init()). A future patch will fix the multi-instance use case (initialization made directly with fsl_esdhc_initialize()).
