HDMI Cape Pin Error?

It looks like the default HDMI cape is claiming one more pin than it
actually needs. The mcasp0_axr1 pin (ball D13, or P9 pin 41.1) is being
claimed by the HDMI overlay:

https://github.com/beagleboard/linux/blob/3.8.13-bone68/firmware/capes/cape-boneblack-hdmi-00A0.dts#L88

...but isn't actually connected to the HDMI framer or anything other
than P9 (and the 'old' P9 pin 41, ball D14) according to the schematic.

Is this a goof as I expect, or is there some reason an unused audio data
line actually needs to be claimed by the HDMI overlay?

Looks like it should be:

0x06c (PIN_OUTPUT_PULLDOWN | MUX_MODE7) /* gpmc_a11.GPIO1_27 */

That looks much more reasonable.

Do you want to fix this, or should I send in a patch? :wink:

If you want to just add it to your current: 3.8.13-xenomai-pbx branch

https://github.com/cdsteinkuehler/linux-dev/commits/3.8.13-xenomai-pbx

I'll pull that along with the two other changes this weekend.

Regards,

I've added a fix to the 3.8.13-xenomai-pbx branch and pushed to github,
so it's ready for you to pull anytime.

Note this branch also has a custom LCD cape for the folks over at
Probotix, which you may or may not want to include. I'm not sure it's
final yet, but I can always just send another patch if it's not. :slight_smile:
