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!
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?
