[PATCH v5 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.

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 ...

changes for v4:
- Interrupt Controller:
  - split in two patches as Nori Sekhar suggested
    one for the irq_domain change
    one for DT support
  - add comment from Grant Likely for the DT part:
    remove if/else clause, not needed.
    Make use of DT runtime configurable
    The non OF case is not tested!

changes for v5:
- Interrupt Controller:
  add comments from Sergei Shtylyov:
  - s/intc/cp_intc in commit subject
  - Codingstyle fixes
  add comment from Grant Likely:
  - rename compatible" prop to "ti,cp-intc"
  - call irq_domain_add also in the non DT case
    (was fixed in v4)
  - switched from using d->irq to d->hwirq for the hardware
    irq number in irq_chip hooks
- I2C DT support:
  add comments from Grant Likely:
  - do not change value of dev->dev->platform_data, instead
    hold a copy in davinci_i2c_dev.
      
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

  This is removed for v4 serie, as Nori Sekhar suggested.

- 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.

  change for v4:
  The 10 ms delay is no longer needed, see discussion here:

  http://www.spinics.net/lists/linux-usb/msg64232.html

  shows the way to go ...

- 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?
