I realized something just last night. I was grabbing changes from the
devel
branch of github.com/utilite-computer, thinking that those changes were based off the vanilla 3.10 kernel. Those changes are actually based on
the
Freescale 3.10 kernel. I pulled a Freescale patch that is obviously
missing:
"ENGR00276249-1 ARM: imx6q: Add missing baud clock for ssi" I also
switched
The baud clock patch is present in 3.18-rc1:
commit 935632e9938e3e286b9c62a7e54d35c428533cc9 Author: Shengjiu Wang shengjiu.wang@freescale.com Date: Tue Sep 9 17:13:26 2014 +0800
ARM: dts: imx6qdl: add baud clock and clock-names for ssi Baud clock is used for bit clock generation in master mode. Ipg clock is peripheral clock and peripheral access clock. Signed-off-by: Shengjiu Wang <shengjiu.wang@freescale.com> Signed-off-by: Shawn Guo <shawn.guo@freescale.cAwesome! It's great to see this stuff go mainline.
I have rebased to 3.18 rc-1. It has simplified the patch set a bit, as more of the Freescale things have hit mainline. http://pastebin.com/C652GKe3 is my patchset. Again, the card registers and thinks it plays, but there is no actual output.
back to imx-wm8731.c for the driver. With this setup, the driver
registers,
and speaker-test thinks it plays, however there is no actual sound
output. I
call it progress.
Great progress: some things to check :
- audmux settings
Well, the imx-wm8731 driver (It's really just glue for loading wm8731) does have audmux settings in it. These get called during the module probe. Not sure what might need to change there. My thoughts are that they should be correct.
- Can you try to run 'alsamixer' and make sure that the volume is not
at the lowest level?
Yeah, I've made sure to check alsamixer and turn the volume up. Still no joy.
