Merge branch 'net-stmmac-fix-timestamp-snapshots-on-dwmac1000'
Alexis Lothore says: ==================== net: stmmac: fix timestamp snapshots on dwmac1000 this is the v2 of a small series containing two small fixes for the timestamp snapshot feature on stmmac, especially on dwmac1000 version. Those issues have been detected on a socfpga (Cyclone V) platform. They kind of follow the big rework sent by Maxime at the end of last year to properly split this feature support between different versions of the DWMAC IP. v1: https://lore.kernel.org/r/20250422-stmmac_ts-v1-0-b59c9f406041@bootlin.com Signed-off-by: Alexis Lothoré <alexis.lothore@bootlin.com> ==================== Link: https://patch.msgid.link/20250423-stmmac_ts-v2-0-e2cf2bbd61b1@bootlin.com Signed-off-by: Paolo Abeni <pabeni@redhat.com>
