From c373eb489b27b268c9b8c267b212d10864bc8cdd Mon Sep 17 00:00:00 2001 From: Seungwon Jeon Date: Wed, 23 Apr 2014 17:15:08 +0900 Subject: mmc: core: add DT bindings for eMMC HS400 1.8/1.2V Provide the option to configure these speed modes per host, for those host driver's that can't distinguish this in runtime. Specially, if host can support HS400, it means that host can also support HS200.
