TAS5805M: Failed to initialize TAS5805M

Part Number: TAS5805M

Hi Team,

Need your urgent help.

We are using TAS5805M audio code with IMX8MM in Android 11 code base.

I'm using same driver for 2 audio codec. 

TAS5805M - 2*20W -->>> This implementation is working fine with I2C add 0x2c and I2C4

TAS5805M - 0.8W -->>> Facing few issue with this implementation.

Not able to load DSP for TAS5805M - 0.8W

Enter into : tas5805m_i2c_probe
tas5805m 1-002d: probe invoked: tas5805m_probe
tas5805m 1-002d: ret = regmap_register_patch TAS5805M: -6
tas5805m 1-002d: Failed to initialize TAS5805M: -6

Could you please review the schematic:

Voltage rails : DVDD is 1.8V

PVDD is 5V

pdn pin voltage 1.8V

I2C communication is working Fine.

Trying load DSP but it is giving -6 error and codec is not getting registered.

Thanks

Divyesh
