[PATCH 00/12] Introduce davinci AEMIF driver

[Khoronzhuk, Ivan]

These patches introduce AEMIF driver for davinci/keystone archs
and defines AEMIF and NAND devices in keystone DT.
Also some changes added to davinci NAND driver in order to reuse it
for Keystone arch.

The patches can be spitted to several series if needed, like

12      - add AEMIF/NAND device entry in DT
arm: dts: keystone: add AEMIF/NAND device entry

9-11    - reuse davinci-nand driver for keystone arch
mtd: nand: davinci: don't request AEMIF address range
mtd: nand: davinci: don't set timings if AEMIF is used
mtd: nand: davinci: reuse driver for Keystone arch

7-8     - introduce AEMIF driver
memory: davinci-aemif: add bindings for AEMIF driver
memory: davinci-aemif: introduce AEMIF driver

4-6     - move davinci-nand bindings under mtd
mtd: nand: davinci: adjust DT properties to MTD generic
mtd: nand: davinci: extend description of bindings
mtd: nand: davinci: move bindings under mtd

1-3     - separate nand fixes
mtd: nand: davinci: simplify error handling
mtd: nand: davinci: check required ti,davinci-chipselect property
mtd: nand: davinci: fix driver registration
