TAS2110: TAS2110 Linux Driver

Chris Garren93

Part Number: TAS2110

I'm working on backporting the 5.8 mainline driver for the TAS2110 into my project. One thing I noticed is that minimum number of channels is specified as 2:

.name = "tas2562-amplifier",
.id = 0,
.playback = {
	.stream_name    = "ASI1 Playback",
	.channels_min   = 2,
	.channels_max   = 2,
	.rates      = SNDRV_PCM_RATE_8000_192000,
	.formats    = TAS2562_FORMATS,
},

I'm also wondering how/if the driver handles the IRQ. I was previously using this driver:

git.ti.com/.../

But am running into problems with the IRQ constantly happening with the TDM Clock Error bit set.

Will I be able to use the mainline driver for a mono TAS2110?

Hi Chris,

Have you tried to use this other set of files? tas256xsw-android/tas2562-android-driver - Software for TAS256x on Android platforms - Android software for Texas Instruments TAS2562. (ti.com)

The link you shared is for stereo driver, the one above here is mono.

Ivan,

Thanks for pointing me to that. I'll try to integrate it, it looks like there are a number of changes needed due to using a newer kernel version. Just curious, is there any reason to use that driver instead of the mainline driver created by Dan Murphy, referenced in this post: https://e2e.ti.com/support/audio/f/6/t/933995?TAS2110-TAS2110-TAS2562-device-tree-for-imx8m-mini ?

Hi Chris,

I think the files were purposed to be implemented in different platforms.
I can check with our SW team on this question.

Hi Ivan,

I'm not sure I understand the last couple messages. Should I be able to use the mainline kernel driver? Or is it recommended to use the ti repo linked above?

Thanks,

Chris Garren

Hi Chris,

Sorry for late response, we're actively supporting the drivers from ti repo, I would suggest to take it from there.
