This has only been tested on the RPI CM4, which has one port. There are other Broadcom chips which may benefit from using the same framework here, although with different register sets. v1->v2: Squash Kconfig into main patch Move config checks into bcm-phy-lib.h Fix delta_ns calculations in adjtime Uppercase mode selector macros Only use NSE_INIT when necessary Remove the inserted Broadcom RX timestamp from the PTP packet Add perout (chip generated) and fsync out (timer generated) Remove PHY_ID_BCM54213PE special casing (needed for rpi tree) Thanks to Lasse Johnsen for pointing out that the chip's periodic output generation isn't sync'd to any time base.
