Request for Comments - Documentation patch to add Correlated Color Temperature (CCT) and RGBC (red/green/blue/clear) data. The addition of CCT and RGBC is afforded by utilizing a 'real channel' type of IIO_CCT, and 4 modifiers of IIO_MOD_LIGHT_CLEAR, IIO_MOD_LIGHT_RED, IIO_MOD_LIGHT_GREEN, and IIO_MOD_LIGHT_BLUE, found in types.h. A trivial addition to industrialio-core.c is required. in_cct0_input will return typically return the color temperature expressed in kelvins. IIO_MODIFIERs are respective of the associated light frequencies for each of the channels.
