7 Pin Multiplex(hwconfig setting)
8 -------------------------------
9 Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex
11 'setenv hwconfig usb2' to enable USB2 and disable eTsec2
12 'setenv hwconfig tdm' to enable TDM and disable Audio
13 'setenv hwconfig audclk:12' to enable Audio(codec clock sources is 12MHz)
15 'setenv hwconfig 'usb2;tdm' to enable USB2 and TDM, disable eTsec2 and Audio
16 'setenv hwconfig 'usb2;audclk:11' to enable USB2 and Audio(codec clock sources
17 is 11MHz), disable eTsec2 and TDM
19 Warning: TDM and AUDIO can not enable simultaneous !
20 and AUDIO codec clock sources only setting as 11MHz or 12MHz !
21 'setenv hwconfig 'audclk:12;tdm' --- error !
22 'setenv hwconfig 'audclk:11;tdm' --- error !
