Re: [PATCH v11 4/4] net: dsa: mv88e6xxx: Add support for mv88e6393x family of Marvell

+/* Support 10, 100, 200, 1000, 2500, 5000, 10000 Mbps (e.g. 88E6393X)
+ * This function adds new speed 5000 supported by Amethyst family.
+ * Function mv88e6xxx_port_set_speed_duplex() can't be used as the register
+ * values for speeds 2500 & 5000 conflict.
+ */

Thanks, that should stop my or somebody else trying to wrong combine
them.

+/* Offset 0x10 & 0x11: EPC */

+static int mv88e6393x_epc_wait_ready(struct mv88e6xxx_chip *chip, int port)
+{
+	int bit = __bf_shf(MV88E6393X_PORT_EPC_CMD_BUSY);
+
+	return mv88e6xxx_port_wait_bit(chip, port, MV88E6393X_PORT_EPC_CMD, bit, 0);
+}

To follow the naming convention, this should really be called mv88e6393x_port_epc_wait_ready

+int mv88e6393x_serdes_irq_enable(struct mv88e6xxx_chip *chip, int port,
+	    int lane, bool enable)

It can be hard to tell in a diff, but the indentation looks wrong
here. 'int lane' should line up with 'struct'.

+{
+	u8 cmode = chip->ports[port].cmode;
+	int err = 0;
+
+	switch (cmode) {
+	case MV88E6XXX_PORT_STS_CMODE_SGMII:
+	case MV88E6XXX_PORT_STS_CMODE_1000BASEX:
+	case MV88E6XXX_PORT_STS_CMODE_2500BASEX:
+	case MV88E6XXX_PORT_STS_CMODE_5GBASER:
+	case MV88E6XXX_PORT_STS_CMODE_10GBASER:
+		err = mv88e6390_serdes_irq_enable_sgmii(chip, lane, enable);
+	}
+
+	return err;
+}
+
+irqreturn_t mv88e6393x_serdes_irq_status(struct mv88e6xxx_chip *chip, int port,
+				 int lane)

Maybe here as well?

+int mv88e6393x_setup_errata(struct mv88e6xxx_chip *chip)

It should have _serdes_ in the name to follow the naming convention.
