From b70ce2ab41cb67ab3d661eda078f7c4029bbca95 Mon Sep 17 00:00:00 2001 From: yankejian Date: Wed, 13 Jan 2016 15:09:58 +0800 Subject: dts: hisi: fixes no syscon fault when init mdio When linux start up, we get the log below: "Hi-HNS_MDIO 803c0000.mdio: no syscon hisilicon,peri-c-subctrl mdio_bus mdio@803c0000: mdio sys ctl reg has not maped" The source code about the subctrl is dealt syscon, but dts doesn't. It cause such fault, so this patch adds the syscon info on dts files to fixes it. Signed-off-by: Kejian Yan Acked-by: Rob Herring Signed-off-by: David S.
