[PATCH v5 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 fixes ethernet support on the P201 reference board (this is
untested though due to lack of hardware).

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 v4:
- fixed bogus statement about patch #7 regarding the P200 board in the
  cover letter (reword it so it mentions what patch actually does:
  fixing ethernet on the P201 board)
- rebased to apply on top of Kevin's v4.11/integ branch since it's
  based on v4.10-rc8 which includes Jerome's Odroid-C2 EEE patch
  (otherwise patch #1 would have a conflict with that patch)

Changes since v3:
- removed "compatible" property from all PHY nodes because that would
  force the kernel to choose the driver for the PHY with the ID from the
  .dts (instead of the actual PHY ID) - see [2] for more information
  (thanks to Andrew Lunn for spotting this). instead the PHY IDs (and
  names) are added as a comment inside the corresponding .dts files.
- rebased to apply on top of Andreas Färber's "ARM64: meson: DT cleanups"
  series

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
