No, there is precedence: PROP_TYPE_BIT's parse_bit(), print_bit(). The fact that it's a bit within a uint32_t rather than bool is implementation detail that shouldn't matter at the -device / info qtree level. > It would be entirely possible to > let the author decide that on a case-by-case basis by using different > property type enums for the same 'bool' type. Possible, but is it wise?
