Troy,
Did you happen to test Audio on DM6446 with the latest on linux-davinci tree?
For the same clock name issue Arun is running into on DM355, the codecs are not
getting detected on DM6446.
Advanced Linux Sound Architecture Driver Version 1.0.20.
No device for DAI tlv320aic3x
No device for DAI davinci-i2s
ALSA device list:
No soundcards found.
I am thinking we are seeing these issues due to the way dm355 (or dm6446)
clocks are defined on linux-davinci tree and the mach-davinci on kernel.org.
>From arch/arm/mach-davinci/dm355.c of kernel.org
CLK("soc-audio.0", NULL, &asp0_clk),
CLK("soc-audio.1", NULL, &asp1_clk),
And from arch/arm/mach-davinci/dm355.c of linux-davinci tree
CLK(NULL, "asp0", &asp0_clk),
CLK(NULL, "asp1", &asp1_clk),
Kevin, any comments?
Thanks
Sneha
