|
* ES7243E_WORK_MODE is used to select digital format, and user must update it for their system
|
* In ES7243E codec driver (es7243e.c), ES7243E_WORK_MODE will be used for digital format setting.
|
*
|
* In normal mode, ES7243E supports four digital formats including I2S, LJ, DSP-A and DSP-B, with
|
* resolution from 16bits to 32bits.
|
* In TDM mode, ES7243E only supports DSP-A TDM, doesn't support DSP-B TDM.
|
* In NFS mode, ES7243E only supports NFS I2S mode, doesn't support DSP or LJ NFS mode.
