Subject: [PATCH] ASoC: tlv320aic32x4: Fix TAS2505/TAS2521 processing block selection
Date: Tue, 20 Jul 2021 22:03:48 +0200 [thread overview]
Message-ID: <20210720200348.182139-1-marex@denx.de> (raw)
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.
Fixes: b4525b6196cd7 ("ASoC: tlv320aic32x4: add support for TAS2505")
