Backport patch merged upstream for rgmii-id support in stmmac-ipq806x. This is needed for some device that directly connets PHY to the gmac port and require rgmii-id phy-modes. Signed-off-by: Christian Marangi <ansuelsmth@gmail.com>

Subject: [PATCH] net: stmmac: dwmac-ipq806x: account for rgmii-txid/rxid/id
|
|
phy-mode
|
|
|
|
Currently the ipq806x dwmac driver is almost always used attached to the
|
|
CPU port of a switch and phy-mode was always set to "rgmii" or "sgmii".
|
|
|
|
Some device came up with a special configuration where the PHY is
|
|
directly attached to the GMAC port and in those case phy-mode needs to
|
|
be set to "rgmii-id" to make the PHY correctly work and receive packets.
|
|
|
|
Since the driver supports only "rgmii" and "sgmii" mode, when "rgmii-id"
|
|
(or variants) mode is set, the mode is rejected and probe fails.
|
|
|
|
Add support also for these phy-modes to correctly setup PHYs that requires
|
|
delay applied to tx/rx.
