I've made a lot of progress getting the DTBO correct for my cape. I think the
CODEC is configured, although I don't know how to test it. But the
simple-sound-card is still giving me some issues. It reports "could not get
#sound-dai-cells for /ocp/mcasp@48038000". I tried adding #sound-dai-cells =
<0>; to the node, but it didn't seem to have any effect. Here's the DTO:
https://github.com/JetForMe/podtique/blob/master/bbb/cape/Podtique1/BB-ENABLE-PRU.dts
And dmesg says this:

I have gpio1[18] controlling two voltage regulators that power the CODEC. The
regulator node seems to bring that up just fine.
gpio1[19] is the active-low reset to the CODEC. I haven't yet seen that go
high, although I haven't put a scope on it during the DTO load to see if it's
getting any traffic.
I'd love to know how to fix the sound node, and how to poke at the CODEC to see
if it's alive (via the driver; I was able to use i2cget to look at registers).
Thanks!
