TAS2505-Q1:How to use TAS2505 linux driver and device tree?

Part Number: TAS2505-Q1
Other Parts Discussed in Thread: TAS2505

hi,

During porting of the tas2505 driver,

I am not familiar with the use of Device Tree, so I am having a hard time porting it.

The tlv320aic32x4 general-purpose driver cannot be used due to the low kernel version,

so we are porting the tas2505 Linux driver on Ti Github.

In the structure data, the sysclk and p_div parameters are being input as 0.

The Linux kernel currently in use is 4.4.120, architecture arm processor

Please provide a device tree manual for tas2505 or a solution to solve the problem.

thank you

- Debug log - 

tas2505-codec 2-0018: Sample rate (48000) and format not supported

tas2505-codec 2-0018: ASoC: can't set tas2505-fifi hw params: -22

- Device tree -

tas2505: tas2505@18{
compatible = "ti,tas2505";
tas2505,gpio-reset = <&gpe 14 0>;
reg = <0x18>; // 0x30 >> 1
};
dai-link@0 {
stream-name="I2S_0";
codec,format = "i2s";
codec,continuous-clock;
pcm = <&adma0>;
dai = <&i2s0>;
codec = <&tas2505>;
codec,dai-name = "tas2505-hifi";
};
