From d83b47b778805e2d3cfc9f6b14437f389f9da49f Mon Sep 17 00:00:00 2001 From: York Sun Date: Mon, 8 Feb 2016 13:04:17 -0800 Subject: [PATCH] arm: ls1021aqds: Convert to driver model and enable serial support Split duart configuration as device tree file. Move /chosen node out of board commone device tree. Convert ls1021aqds nor and SD configurations to driver model support (qspi already uses DM). Enable ns16550 DM serial driver for nor configurations.
