[PATCH v3 3/3] arm:davinci: move NAND and NOR devices as aemif MFD slaves

Manjunathappa, Prakash prakash.pm at ti.com
Tue Feb 7 10:11:53 EST 2012


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 at ti.com>
---
Since v2:
Make changes for all DaVinci boards in single patch.
Since v1:
Patch generated using -M option.
