PCM1864 驱动加载

Other Parts Discussed in Thread: PCM1864

Dear All:

  请问PCM1864的驱动在设备树该如何描述呢:

1. 我使用的不是TI的LINUX内核,是另外一款SOC的LINUX内核

2. 我在设备树做了以下描述:

        ps7-i2c@e0004000 {
            bus-id = <0x0>;
            clocks = <0x2 0x26>;
            compatible = "cdns,i2c-r1p10";
            clock-frequency = <0x186a0>;
            interrupt-parent = <0x3>;
            interrupts = <0x0 0x19 0x4>;
            reg = <0xe0004000 0x1000>;
            xlnx,has-interrupt = <0x0>;
            
            pcm1864@4a {
                compatible = "pcm1864";
                reg = <0x4a>;
            };
        };

3. 我得到了以下错误信息:

pcm186x 0-004a: pcm186x_i2c_probe() i2c->addr=74
0-004a supply avdd not found, using dummy regulator
0-004a supply dvdd not found, using dummy regulator
0-004a supply iovdd not found, using dummy regulator

4. 系统起来后,我看不到声信息:

root@test:/sys/class/sound/timer# ls
dev        power      subsystem  uevent

能在哪里找到PCM1864的完整驱动样例?包括设备树以及上层应用程序?
