Hi all,

          

kernel 3.10.53:

 

pinctrl_esai_3: esaigrp-3 {
 fsl,pins = <
MX6QDL_PAD_GPIO_6__ESAI_TX_CLK 0x1b030
MX6QDL_PAD_GPIO_2__ESAI_TX_FS 0x1b030

MX6QDL_PAD_GPIO_7__ESAI_TX4_RX1 0x1b030
MX6QDL_PAD_GPIO_8__ESAI_TX5_RX0 0x1b030
MX6QDL_PAD_GPIO_17__ESAI_TX0 0x1b030

MX6QDL_PAD_GPIO_18__ESAI_TX1 0x1b030
>;
};

 

I want TX0 and TX1 to output different audio data.      Is it possible to do that?

What should be configured in the driver?

 

Thanks
