Subject: [PATCH v4 3/3] arm:davinci: move NAND and NOR devices as aemif MFD slaves
NAND and NOR device are made as aemif device slaves, hence all DaVinci
board NAND/NOR device registration achieved via aemif MFD driver.
Signed-off-by: Manjunathappa, Prakash <prakash.pm@...com>
---
Since v3:
Changed NAND device id to 1 for board-mityomapl138.
Since v2:
Make changes for all DaVinci boards in single patch.
Since v1:
Patch generated using -M option.
