+ VSC7512 (Ocelot-Ext):
+
+ The Ocelot family consists of four devices, the VSC7511, VSC7512, VSC7513,
+ and the VSC7514. The VSC7513 and VSC7514 both have an internal MIPS
+ processor that natively support Linux. Additionally, all four devices
+ support control over external interfaces, SPI and PCIe. The Ocelot-Ext
+ driver is for the external control portion.
+
+ The following PHY interface types are supported:
+
+ - phy-mode = "internal": on ports 0, 1, 2, 3
+ - phy-mode = "sgmii": on ports 4, 5, 7, 8, 9, 10

The ocelot-ext driver is another sub-device of the Ocelot / Felix driver system. It requires a register array similar to the VSC7514 and has different ports layout than existing devices. Signed-off-by: Colin Foster <colin.foster@in-advantage.com> --- v4 * Add documentation for all supported modes (qsgmii / sgmii) * /s/7412/7512 * Changes to match the VSC7514 device tree, including: - Replace ethernet-switch@0 to ethernet-switch@71010000 - Add all reg / reg-names entries * Add example entries for ports 4-7, which requires phy-ocelot-serdes.h * Add the last sentence to the commit description, which replaces the phrase "which currently supports the four internal copper phys" * Remove "spi {" node from the documentation * Remove "cpu" label from port 0 * Add "soc { reg = <0 0>;" to fix dt_binding_check warning v3 * Remove "currently supported" verbage The Seville and Felix 9959 all list their supported modes following the sentence "The following PHY interface types are supported". During V2, I had used "currently supported" to suggest more interface modes are around the corner, though this had raised questions. The suggestion was to drop the entire sentence. I did leave the modified sentence there because it exactly matches the other two supported products. v2 * New patch --- .../bindings/net/dsa/mscc,ocelot.yaml | 112 ++++++++++++++++++ 1 file changed, 112 insertions(+)
