27 * PMBUS_SKIP_STATUS_CHECK
29 * During register detection, skip checking the status register for
30 * communication or command errors.
32 * Some PMBus chips respond with valid data when trying to read an unsupported
33 * register. For such chips, checking the status register is mandatory when
34 * trying to determine if a chip register exists or not.
35 * Other PMBus chips don't support the STATUS_CML register, or report
36 * communication errors for no explicable reason. For such chips, checking
37 * the status register must be disabled.
