Hello everyone,
This series follows-up on the worki [1] aiming at dropping the altera TSE PCS driver, as it turns out to be a version of the Lynx PCS exposed as a memory-mapped block, instead of living on an MDIO bus.
One step of this removal involved creating a regmap-based mdio driver that translates MDIO accesses into the actual underlying bus that exposes the register. The register layout must of course match the standard MDIO layout, but we can now account for differences in stride with recent work on the regmap subsystem [2].
Mark, Net maintainers, this series depends on the patch e12ff2876493 that was recently merged into the regmap tree [3].
For this series to be usable in net-next, this patch must be applied beforehand. Should Mark create a tag that would then be merged into net-next ?
This series introduces a new MDIO driver, and uses it to convert Altera TSE from the actual TSE PCS driver to Lynx PCS.
Since it turns out dwmac_socfpga also uses a TSE PCS block, port that driver to Lynx as well.
Thanks,
Maxime
