7Pin Multiplex(hwconfig setting)
8-------------------------------
9Add the environment 'usb2', 'audclk' and 'tdm' to support pin multiplex
10via hwconfig, i.e:
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)
14 and disable TDM
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
18
19Warning: TDM and AUDIO can not enable simultaneous !
20and AUDIO codec clock sources only setting as 11MHz or 12MHz !
21'setenv hwconfig 'audclk:12;tdm' --- error !
22'setenv hwconfig 'audclk:11;tdm' --- error !
23'setenv hwconfig 'audclk:10' --- error !
