One more thing to discuss (Jonathan, what's your opinion?) I think the
following easier to understand and has less problematic characters in the names
(in case of sysfs direct use from shelll):

static const char * const chan7_vol[] = {
"gnd", // alternatively GND
"0.25vdd", // alternatively 0.25_vdd, 0.25Vdd, 0.25_Vdd
"0.5vdd",
"0.75vdd",
"vdd", // Vdd
"ch7_input",
};

That said, my personal preference:

static const char * const chan7_vol[] = {
"GND",
"0.25Vdd",
"0.5Vdd",
"0.75Vdd",
"Vdd",
"ch7_input",
};
