Hi Shenghao Ding

I don't see tas2110xxx.c in https://git.ti.com/cgit/lpaa-android-drivers/tasdevice-linux-driver/tree/src

Could you update tas2110 driver to https://git.ti.com/cgit/lpaa-android-drivers/tasdevice-linux-driver/tree/src, thanks.

Hi, Shine

tas2110 register map is similar to tas2770, so no extra c&h files are needed.

Actually, you can check the commit logs, we have already uploaded some codes related to tas2110.

Hi Shenghao Ding,

I got error after command "insmod /lib/snd-soc-tasdevice.ko"

# insmod /lib/snd-soc-tasdevice.ko
[ 16.354071] tasdevice-codec 0-0048: Primary-device = 0x48
[ 16.359489] tasdevice-codec 0-0048: Looking up irq-gpio property failed -22
#

My device tree:

tas2110: tasdevice@48 {
compatible = "ti,tas2110";
#sound-dai-cells = <0>;
reg = <0x48>;
ti,topleft-channel = <0x48>;
ti,reset-gpio0 = <&gpio 98 1>;
ti,irq-gpio = <&gpio 99 1>;
};

If I use interrupt-free DTS setting:

tas2110: tasdevice@48 {
compatible = "ti,tas2110";
reg = <0x48>;
#sound-dai-cells = <0>;
reset-gpios = <&gpio 98 1>;
};

The command "insmod /lib/snd-soc-tasdevice.ko" has same error "tasdevice-codec 0-0048: Looking up irq-gpio property failed -22"

Are my DTS settings correct?

Pls use reset-gpios instead of ti,reset_gpio0; Per the irq error, this means the irq code on BBB can run well on your platform, you will have some modification on your platform. But do not care the irq error, now. It does not have some side effect.
