AM437x-epos (next-20140409-omap2plus_defconfig) - boot time warning: qspi/otg..

Hi,
http://slexy.org/raw/s2pkLsiFBX

I noticed the following sets of warnings with omap2plus_defconfig on next-20140409. As per older logs, next-20140401 had it and v3.14 tag also had it (I have'nt retained older logs).

Hi Nishant,

I remember George had sent patches to add USB DT nodes for am43xx. Looks like they didn't get through.

Adding the USB nodes should get rid of the warning.

George,

Can you please resend a minimal set to fix this warning for -rc? Thanks.

cheers,

Hi Nishanth,

The dts date were posted but due to some functional changes going in spi core, the dts data were not picked(predictiong some changes in dt parameters). I will send a minimal qspi node during rc cycle to get rid of this warning.

Here is a quick list of 20 odd boards I am testing with:

Nishant,

these 2 usb host/tll messages seem to appear for all OMAP3 based boards. Seems like incorrect hwmod data. I'll send a patch to fix this.

cheers,
