net: stmmac: implement support for passive mode converters via dt

2019-09-11T14:27:09Z

In-between the MAC & PHY there can be a mode converter, which converts one mode to another (e.g. GMII-to-RGMII). The converter, can be passive (i.e. no driver or OS/SW information required), so the MAC & PHY need to be configured differently. For the `stmmac` driver, this is implemented via a `mac-mode` property in the device-tree, which configures the MAC into a certain mode, and for the PHY a `phy_interface` field will hold the mode of the PHY. The mode of the PHY will be passed to the PHY and from there-on it work in a different mode. If unspecified, the default `phy-mode` will be used for both.

net: stmmac: Make MDIO bus reset optional

2019-07-27T20:52:26Z

The Tegra EQOS driver already resets the MDIO bus at probe time via the reset GPIO specified in the phy-reset-gpios device tree property. There is no need to reset the bus again later on. This avoids the need to query the device tree for the snps,reset GPIO, which is not part of the Tegra EQOS device tree bindings. This quiesces an error message from the generic bus reset code if it doesn't find the snps,reset related delays. Signed-off-by: Thierry Reding Signed-off-by: David S. Miller

net: stmmac: drop the phy_reset hook from struct stmmac_mdio_bus_data

2019-06-16T20:53:41Z

The phy_reset hook is not set anywhere. Drop it to make stmmac_mdio_reset() smaller. Signed-off-by: Martin Blumenstingl Signed-off-by: David S. Miller

net: stmmac: drop the reset delays from struct stmmac_mdio_bus_data

2019-06-16T20:53:41Z

Only OF platforms use the reset delays and these delays are only read in stmmac_mdio_reset(). Move them from struct stmmac_mdio_bus_data to a stack variable inside stmmac_mdio_reset() because that's the only usage of these delays. Signed-off-by: Martin Blumenstingl Signed-off-by: David S. Miller

net: stmmac: drop the reset GPIO from struct stmmac_mdio_bus_data

2019-06-16T20:53:41Z

No platform uses the "reset_gpio" field from stmmac_mdio_bus_data anymore. Drop it so we don't get any new consumers either. Plain GPIO numbers are being deprecated in favor of GPIO descriptors. If needed any new non-OF platform can add a GPIO descriptor lookup table. devm_gpiod_get_optional() will find the GPIO in that case.

net: stmmac: Fix wrapper drivers not detecting PHY

2019-06-15T20:58:28Z

Because of PHYLINK conversion we stopped parsing the phy-handle property from DT. Unfortunatelly, some wrapper drivers still rely on this phy node to configure the PHY. Let's restore the parsing of PHY handle while these wrapper drivers are not fully converted to PHYLINK.

net: stmmac: use GPIO descriptors in stmmac_mdio_reset

2019-06-15T02:08:40Z

Switch stmmac_mdio_reset to use GPIO descriptors. GPIO core handles the "snps,reset-gpio" for GPIO descriptors so we don't need to take care of it inside the driver anymore. The advantage of this is that we now preserve the GPIO flags which are passed via devicetree. This is required on some newer Amlogic boards which use an Open Drain pin for the reset GPIO. This pin can only output a LOW signal or switch to input mode but it cannot output a HIGH signal. There are already devicetree bindings for these special cases and GPIO core already takes care of them but only if we use GPIO descriptors instead of GPIO numbers.
