So, are they good?
If your hardware really uses these pins, then yes :-)
Now looking at other boards where our hardware-guy took the inspiration
(i.e. iMX6 Rex from Fedevel) the device-tree is the same as mine.
MX6QDL_PAD_GPIO_0__CCM_CLKO1 0x030b0
0x130b0 or 0x030b0 the only difference is the PAD_CTL_HYS
(1 << 16)
Maybe more strong to noise, but basically they are the same.
But I found an issue when playing data from aplay without specifing the
device or specifying one:
# aplay /usr/share/sounds/alsa/Front_Center.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
or
# aplay -D hw:0,0 /usr/share/sounds/alsa/Front_Right.wav
Playing WAVE 'Front_Center.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono
aplay: set_params:1233: Sample format non available
Available formats:
- S24_LE
Maybe some ALSA misconfigured????
This distro is a bootstrapped jessie Debian 8, so some configuration
could be missing or not-so-good-configured.
# aplay -L
null
