[beagleboard] conflict with cape-bone-iio overlay and simple pinmux overlay?

2014-02-21 Thread cfalk3

Hello,

I am trying to use both the cape-bone-iio device tree overlay for analog 
input, and a simple pin-muxing overlay (see attached DTS file) to change 
the direction of various gpio pins.  Although they both work on their own, 
it seems that there is a problem when loaded together.  The first overlay 
always works, and the second *seems* to load just fine, but does not take 
effect..

*Example 1 (first load cape-bone-iio, then DM-GPIO-Test)*

I am not sure how to attach a file, so here is my DTS file...

/dts-v1/;
/plugin/;

/{
   compatible = ti,beaglebone, ti,beaglebone-black;
   part-number = DM-GPIO-Test;
   version = 00A0;

   fragment@0 {
 target = am33xx_pinmux;

 __overlay__ {

Hi Jason,

Yes, I was using Derek Molloy's DTS file as a template.  The only 
difference is that I edited it for the following

0x198 0x37  /* P9_30 102 OUTPUT MODE7 */

I posted the relevant dmesg output in my first post.  I wasn't sure how to 
attach a file to this thread...

Guy:
  I did look at both DTS files and as far as I could tell there is not a 
conflict with pins.  I also tried assigning other GPIO pins values, and 
those did not take effect either.

 I don't see an attachment. Googling for the name I found 
 https://github.com/derekmolloy/boneDeviceTree/blob/master/overlay/DM-GPIO-Test.dts.
  
 Is this the same file or did you edit it?
  

 to change the direction of various gpio pins.  Although they both work on 
 their own, it seems that there is a problem when loaded together.  The
