From 95e1e7e7572b3ec97dba1e4caa06f06294d4b5dd Mon Sep 17 00:00:00 2001 From: Caesar Wang Date: Fri, 15 Jan 2016 21:49:54 +0800 Subject: [PATCH] UPSTREAM: ARM: dts: rockchip: add the sdmmc for kylin board Although We can add the sdmmc node, shouldn't enable it. Since the sdmmc is reusing the same pin with uart2. Unfortunately, the uart2 is used by the debug port, so that will cause the debug information can't display on console if enabling the sdmmc. As we have supported the sdmmc (sd card) on hardware for kylin board. So, maybe we can have the sdmmc node in kylin dts, not to enable it. Anyway, you only need add the okay status if someone want to enable the sdmmc. e.g. if you use the adb to debug with android os. You can add the status = "okay" to enable the sdmmc for sd card working. The default status is disabling it.
