L2 works fine without this bit. If this is needed for V3 hardware, then it should have its own code variant. > while at that rename TS_BIT8 to TS_TTL_NONZERO Is this bit finally documented for am335x? Thanks, Richard

Not for am335x, but for other SoC's it s documented. > Thanks, > Richard >

Enable the Annex F Time Sync explicitly for DRA7x and AM4372. With this enabled the L2 PTP is working. while at that rename TS_BIT8 to TS_TTL_NONZERO Signed-off-by: George Cherian <george.cherian@ti.com> --- drivers/net/ethernet/ti/cpsw.c | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-)
