Here as well, default for bit_pos should be 0.
This means when 'None' of the options are selected, by default, it enumerates to 0. Since we are using __ffs, BIT(0) of Register-0 also enumerates to 0. That's the reason why I used just ffs in the first place. Let me know your opinion. My value table looks like below.
#define MUX_VALUE(npart, nbit) (nbit + 32 * npart) static const int mux_values[] = { 0, MUX_VALUE(0, 0), . . . MUX_VALUE(0, 31), /* above inputs are for part0 mux */ MUX_VALUE(1, 0), . . . MUX_VALUE(1, 31), /* above inputs are for part1 mux */ MUX_VALUE(2, 0), . . . MUX_VALUE(2, 31), /* above inputs are for part2 mux */ };
Ok, so having none of the input selected should be a valid user selectable option?
