net: mscc: ocelot: un-export unused regmap symbols

2023-02-07T06:33:15Z

There are no external users of the vsc7514_*_regmap[] symbols or vsc7514_vcap_* functions. They were exported in commit 32ecd22ba60b ("net: mscc: ocelot: split register definitions to a separate file") with the intention of being used, but the actual structure used in commit 2efaca411c96 ("net: mscc: ocelot: expose vsc7514_regmap definition") ended up being all that was needed. Bury these unnecessary symbols.

The VSC7514 target regmap is identical for ones shared with similar hardware, specifically the VSC7512. Share this resource, and change the name to match the pattern of other exported resources.

Resetting the switch core is the same whether it is done internally or externally. Move this routine to the ocelot library so it can be used by other drivers.

The vcap_props structure is common to other devices, specifically the VSC7512 chip that can only be controlled externally. Export this structure so it doesn't need to be recreated.

The ocelot_regfields struct is common between several different chips, some of which can only be controlled externally. Export this structure so it doesn't have to be duplicated in these other drivers. Rename the structure as well, to follow the conventions of other shared resources.

net: mscc: ocelot: add MAC Merge layer support for VSC9959

2023-01-23T12:44:18Z

Felix (VSC9959) has a DEV_GMII:MM_CONFIG block composed of 2 registers (ENABLE_CONFIG and VERIF_CONFIG). Because the MAC Merge statistics and pMAC statistics are already in the Ocelot switch lib even if just Felix supports them, I'm adding support for the whole MAC Merge layer in the common Ocelot library too. There is an interrupt (shared with the PTP interrupt) which signals changes to the MM verification state. This is done because the preemptible traffic classes should be committed to hardware only once the verification procedure has declared the link partner of being capable of receiving preemptible frames. We implement ethtool getters and setters for the MAC Merge layer state. The "TX enabled" and "verify status" are taken from the IRQ handler, using a mutex to ensure serialized access.

net: mscc: ocelot: export ethtool MAC Merge stats for Felix VSC9959

2023-01-23T12:44:18Z

The Felix VSC9959 switch supports frame preemption and has a MAC Merge layer. In addition to the structured stats that exist for the eMAC, export the counters associated with its pMAC (pause, RMON, MAC, PHY, control) plus the high-level MAC Merge layer stats. The unstructured ethtool counters, as well as the rtnl_link_stats64 were left to report only the eMAC counters. Because statistics processing is quite self-contained in ocelot_stats.c now, I've opted for introducing an ocelot->mm_supported bool, based on which the common switch lib does everything, rather than pushing the TSN-specific code in felix_vsc9959.c, as happens for other TSN stuff.

net: mscc: ocelot: remove unnecessary exposure of stats structures

2022-11-22T14:36:43Z

Since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat definitions between all drivers") there is no longer a need to share the stats structures to the world. Relocate these definitions to inside ocelot_stats.c instead of a global include header. Signed-off-by: Colin Foster Reviewed-by: Vladimir Oltean Signed-off-by: Paolo Abeni

Ever since commit 4d1d157fb6a4 ("net: mscc: ocelot: share the common stat definitions between all drivers") the stats_layout entry in ocelot and felix drivers have become redundant.
