| Pin Multiplex(hwconfig setting) |
| ------------------------------- |
| Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex |
| via hwconfig, i.e: |
| 'setenv hwconfig usb2' to enable USB2 and disable eTsec2 |
| 'setenv hwconfig tdm' to enable TDM and disable Audio |
| 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz) |
| and disable TDM |
| 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio |
| 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources |
| is 11MHz), disable eTsec2 and TDM |
| |
| Warning: TDM and AUDIO can not enable simultaneous ! |
| and AUDIO codec clock sources only setting as 11MHz or 12MHz ! |
| 'setenv hwconfig 'audclk:12;tdm' --- error ! |
| 'setenv hwconfig 'audclk:11;tdm' --- error ! |
| 'setenv hwconfig 'audclk:10' --- error ! |
