The TAS2505/TAS2521 does support only three processing block options, unlike TLV320AIC32x4 which supports 25. This is documented in TI slau472 2.5.1.2 Processing Blocks and Page 0 / Register 60: DAC Instruction Set - 0x00 / 0x3C.
Limit the Processing Blocks maximum value to 3 on TAS2505/TAS2521 and select processing block PRB_P1 always, because for the configuration of teh codec implemented in this driver, this is the best quality option.
