The COMP1_TX_WORDSIZE_0/COMP2_RX_WORDSIZE_0 fields in the comp registers indicate the maximum wordsize supported. DWC I2S controller can operate with any smaller wordsize. So extend the formats to let I2S to operate in any allowed modes.

[PATCH] ASoC: fsl_sai: MCLK bind with TX/RX enable bit
by Shengjiu Wang 09 May '23

09 May '23

On i.MX8MP, the sai MCLK is bound with TX/RX enable bit, which means the TX/RE enable bit need to be enabled then MCLK can be output on PAD. Some codec (for example: WM8962) needs the MCLK output earlier, otherwise there will be issue for codec configuration. Add new soc data "mclk_with_tere" for this platform and enable the MCLK output in startup stage. As "mclk_with_tere" only applied to i.MX8MP, currently The soc data is shared with i.MX8MN, so need to add an i.MX8MN own soc data with "mclk_with_tere" disabled.
