This binding addresses + these 'input' properties. For example, it is common for the 'reg' property + (an 'output' property) to be set by Binman, based on the alignment requested + in the input. + + Once processing is complete, input properties have mostly served their + purpose, at least until the firmware is repacked later, e.g. due to a + firmware update.
