Subject: [PATCH net-next 0/2] RGMII delays for SJA1105 DSA driver
Date: Sat, 8 Jun 2019 19:12:26 +0300 [thread overview]
Message-ID: <20190608161228.5730-1-olteanv@gmail.com> (raw)
This patchset configures the Tunable Delay Lines of the SJA1105 P/Q/R/S
switches. These add a programmable phase offset on the RGMII RX and TX
clock signals and get used by the driver for fixed-link interfaces that
use the rgmii-id, rgmii-txid or rgmii-rxid phy-modes.
Tested on a board where RGMII delays were already set up, by adding
MAC-side delays on the RGMII interface towards a BCM5464R PHY and
noticing that the MAC now reports SFD, preamble, FCS etc. errors.
Conflicts trivially in drivers/net/dsa/sja1105/sja1105_spi.c with
https://patchwork.ozlabs.org/project/netdev/list/?series=112614&state=*
which must be applied first.
