[PATCH V5 0/4] ARM: Kirkwood: Add support for DNS-320 and DNS-325 using devicetree

[Jamie Lentin <jm@lentin.co.uk>]

Reworked patch for latest feedback. I'm still basing this on Jason Cooper's
tree, given how much time has passed should I be rebasing against something
else or is this still fine?

One thing I noticed is that with only the first patch applied (which no
longer calls kirkwood_nand_init) the device either locks up or serial console
dies at "Gating clock of unused units", presumably as CGC_RUNIT isn't set.
Is this something known or is it worth further investigation?

Thanks again to everyone reviewing.

Changes since v4: Convert DNS-325 & DNS-320 to access nand via devicetree
* Add initial support patch back in to address following comments
** One MACH_DLINK_KIRKWOOD_DT for all dtb files [Grant Likely, Jason Cooper]
** Drop brain-dead select "select CONFIG_MTD_OF_PARTS" [Grant Likely]
** Don't add NAND support then throw it away immediately after [Grant Likely]
* WARN when bank-width is out of range [Andrew Lunn]
* Describe purpose of MPP 41, 42 & 49

Changes since v3: Add support for DNS-320 and DNS-325 using devicetree
* Remove patches that are already merged
* Add documentation on orion_nand devicetree bindings
* Convert bank-width to be in bytes to match other properties
* Make defaults more explicit

Changes since v2: Add support for DNS-320 and DNS-325 using devicetree
* Split patches further, separating orion_nand and kirkwood changes
* dts renames: "bank-width", not "width". "okay", not "ok"
* Separate documentation out into separate patch, add references to
  partition.txt to all mtd bindings.

Changes since v1: Add support for DNS-320 and DNS-325 using devicetree
* Rebase against kirkwood_dt_for_3.4, removing premature devicetree ports.
* Move additions into a separate board-dnskw.c. It could be separated further
  into a board-dns320.c and board-dns325.c but it probably isn't worth it.
* s/marvell,/mrvl,/g
* Include an example dtb partition in documentation
* Copy structure of serial nodes to allow common options for NAND to be set
  in kirkwood.dtsi
* Simplifications in orion-nand.c
