sdmmc is never going to do anything other than switch this entire
bank all at once. so in this particular example, sdmmc returns:
- (['CMD+', 'CLK+', 'D0*', 'D1*', 'D2*', 'D3*'] # pin names
- ['D0*', 'D1*', 'D2*', 'D3*']) # ganged bus names
+ (['CMD+', 'CLK+', 'D0*', 'D1*', 'D2*', 'D3*'] # pin names
+ ['D0*', 'D1*', 'D2*', 'D3*']) # ganged bus names
+
+ addition:
+
+ 3rd item in list gives the name of the clock.
