[PATCH v3 0/7] ARM: davinci: add support for the am1808 based enbw_cmc board

[Heiko Schocher <hs-ynQEQJNshbs@public.gmane.org>]

This patchserie add support for the davinci am1808 based
enbw_cmc board.

Important: I rebased this patchserie against the irqdomain/next
branch from grant likely, as he suggested to rework the OF
intcontroller changes to the irqdomain work, branch found here:

http://git.secretlab.ca/?p=linux-2.6.git;a=shortlog;h=refs/heads/irqdomain/next

    git://git.secretlab.ca/git/linux-2.6.git irqdomain/next

    commit 280ad7fda5f95211857fda38960f2b6fdf6edd3e

    mfd: twl-core: Add IRQ_DOMAIN dependency

changes for v2:
Post this patchserie now as v2, as reworked in the
comments I got for the RFC serie.

changes for v3:
- Interrupt Controller:
  - comment from Sergei Shtylyov:
    - rename compatible" prop to "ti,cp_intc"
    - cp_intc_init() is now also for the of case
      the name of the init function (it calls the
      "new" __cp_intc_init() function, which was
      the "old" cp_intc_init()). Through this
      rework the changes for OF is better visible.
      As the OF case uses the irq_domain rework from
      Grant Likely, maybe the none OF case can use
      this also, but this should be tested on a hw ...
 
Got no comments to the following points, I noted in the
RFC series, so posting this patchseries with them:

- ARM: davinci: configure davinci aemif chipselects through OF
  not moved to mfd, as mentioned in this discussion:
  http://davinci-linux-open-source.1494791.n2.nabble.com/PATCH-arm-davinci-configure-davinci-aemif-chipselects-through-OF-td7059739.html
  instead use a phandle in the DTS, so drivers which
  uses the davinci aemif, can call davinci_aemif_setup_timing_of()

  This is just thought as an RFC ... The enbw_cmc board
  support not really need to setup this bus timings, as
  they are setup in U-Boot ... but I want to post this,
  as I think, it is a nice to have, and I am not really
  sure, if this has to be a MFD device (If so, all bus
  interfaces for other SoCs should be converted also to
  MFD devices) ... as an example how this can be used
  I add this to the davinci nand controller OF support
  patch, in this patchserie.

- ARM: davinci: mux: add OF support
  I want to get rid of the pin setup code in board code ...
  This patch introduces a davinci_cfg_reg_of() function,
  which davinci drivers can call, if they found a
  "pinmux-handle", so used in the following drivers in
  this patchserie:

  drivers/net/ethernet/ti/davinci_emac
  drivers/i2c/busses/i2c-davinci.c
  drivers/mtd/nand/davinci_nand.c

- post this board support with USB support, even though
  USB is only working with the 10 ms "workaround", posted here:
  http://comments.gmane.org/gmane.linux.usb.general/54505
  I see this issue also on the AM1808 TMDXEXP1808L evalboard.

- MMC and USB are not using OF support yet, ideas how to port
  this are welcome. I need for USB and MMC board specific
  callbacks, how to solve this with OF support?
