WebbWhen specific delays are defined in device-tree, phy_get_internal_delay does the lookup automatically returning an index. The default case wrongly assigns the nanoseconds value from the lookup table, resulting in numeric value 2000 applied to delay configuration register, rather than the expected index values 0-7 (7 for 2000). healthyazplus.gov https://allcroftgroupllc.com
