[PATCH RESEND 2/3] ARM: dts: NSP: Add NAND Support to DT

Jon Mason jonmason at broadcom.com
Mon Nov 2 10:40:57 PST 2015


Add NAND support to the device tree for the Broadcom Northstar Plus SoC.
Since no driver changes are needed to enable this hardware, only the
device tree changes are required to make this functional.
