The k3-socinfo.c driver generates the revision string for different variants of the same SoC in an incremental fashion. This is not true for all SoCs. An example case being J721E, for which the actual silicon revision names are 1.0, 1.1 for its variants, while the k3-socinfo.c driver interprets these variants as revisions 1.0, 2.0 respectively, which is incorrect. While the work to fixup the silicon revision string is posted to the soc tree, this patch serves as a fail-safe step by maintaining a list of correct and incorrect revision strings, so that the fixup work does not break the errata workaround for such corrected SoCs. The silicon revisions affected by the errata i2329 can be found under the MDIO module in the "Advisories by Modules" section of each SoC errata document listed below AM62x: https://www.ti.com/lit/er/sprz487c/sprz487c.pdf AM64X: https://www.ti.com/lit/er/sprz457g/sprz457g.pdf AM65X: https://www.ti.com/lit/er/sprz452i/sprz452i.pdf J7200: https://www.ti.com/lit/er/sprz491d/sprz491d.pdf J721E: https://www.ti.com/lit/er/sprz455d/sprz455d.pdf J721S2: https://www.ti.com/lit/er/sprz530b/sprz530b.pdf Signed-off-by: Ravi Gunasekaran --- Changes since v1: * For J721E, retained the incorrect SR ID and added the correct one * Add AM65x SR2.1 to the workaround list v1: https://lore.kernel.org/all/20231018140009.1725-1-r-gunasekaran@ti.com/ drivers/net/ethernet/ti/davinci_mdio.c | 2 ++ 1 file changed, 2 insertions(+) base-commit: 2030579113a1b1b5bfd7ff24c0852847836d8fd1 diff --git a/drivers/net/ethernet/ti/davinci_mdio.c b/drivers/net/ethernet/ti/davinci_mdio.c index 628c87dc1d28..25aaef502edc 100644 --- a/drivers/net/ethernet/ti/davinci_mdio.c +++ b/drivers/net/ethernet/ti/davinci_mdio.c @@ -516,9 +516,11 @@ static const struct soc_device_attribute k3_mdio_socinfo[] = { { .family = "AM64X", .revision = "SR2.0", .data = &am65_mdio_soc_data }, { .family = "AM65X", .revision = "SR1.0", .data = &am65_mdio_soc_data }, { .family = "AM65X", .revision = "SR2.0", .data = &am65_mdio_soc_data }, + { .family = "AM65X", .revision = "SR2.1", .data = &am65_mdio_soc_data }, { .family = "J7200", .revision = "SR1.0", .data = &am65_mdio_soc_data }, { .family = "J7200", .revision = "SR2.0", .data = &am65_mdio_soc_data }, { .family = "J721E", .revision = "SR1.0", .data = &am65_mdio_soc_data }, + { .family = "J721E", .revision = "SR1.1", .data = &am65_mdio_soc_data }, { .family = "J721E", .revision = "SR2.0", .data = &am65_mdio_soc_data }, { .family = "J721S2", .revision = "SR1.0", .data = &am65_mdio_soc_data}, { /* sentinel */ },
