[PATCH v3 0/9] meson-gx: reset RGMII PHYs and configure TX delay

[Martin Blumenstingl]

This series adds the reset GPIOs for the (external) ethernet PHYs on all
GXBB boards.
Additionally it provides a ethernet PHY node which can be used to specify
PHY-specific properties (this may be required if more boards require the
"eee-broken-1000t" for the RTL8211F ethernet PHY). To make all board .dts
consistent I chose to add the PHY node also for boards which don't have a
RTL8211F PHY.

Patch #7 from this series also removes ethernet support for the P200
board because it was broken anyways and nobody seems to have a board
available for testing. This was the outcome of the discussion from [0]

Patch #8 was taken from (older versions of) my other series (see [1]):
"[PATCH net-next v3 0/2] stmmac: dwmac-meson8b: configurable
RGMII TX delay".
The binding changes for amlogic,tx-delay-ns were ACK'ed already.

Changes since v2:
- fixed patch #2 to really update the P200 board (as it's the P200 which
  actually uses a Micrel KSZ9031 RGMII PHY). Thanks to Neil Armstrong for
  spotting this huge mistake!
- instead of dropping ethernet support for P201 we simply re-configure it
  to RMII mode (replaces patch #7) without a MDIO node (which keeps PHY
  auto-scanning enabled). This got Neil Armstrong's ACK off-list already

Changes since v1:
- do not move the MDIO bus to meson-gx as this disables PHY auto-scanning
  in the stmmac driver (this drops patch #1 from v1)
- add the ethernet PHY reset GPIO for nexbox a95x which was forgotten in
  v1
- add the ethernet PHY reset GPIO for boards which were added since v1
  (wetek hub and wetek play2)
- rebased to apply against the current v4.11/dt64 branch
- new in v2 (patch #7): disabled ethernet support for the P200 board (see
  the commit description for more information). this patch is optional
- new in v2 (patch #9): removed the phy-mode property from meson-gx (see
  the commit description for more information). this patch is optional
