[PATCH v4 00/12] phy: atheros: dt bindings and cleanup

[Michael Walle]

This patch series superseeds the following two:
>From Vladimir Oltean
  https://patchwork.ozlabs.org/cover/1031360/
>From me:
  https://patchwork.ozlabs.org/cover/1184507/

Although the first is marked as accepted into u-boot-net I guess it was
removed due to broken boards ("DT as ABI", RGMII delay was fixed and thus
breaks the board).

After disussing with Vladimir, I've integrated his patches with this
series. Also the first one
  Address packet drops at low traffic rate due to SmartEEE feature
was dropped because it will likely be fixed by making u-boot support the
eee-broken-X device tree properties. Apart from that, only the subject was
changed and a note about possible board breakage was added the patch which
changes the delay behaviour.

For all of those, who will test this patchset, the device tree binding
needs the phydev->node property, which needs to be set in every network
driver. If the device tree binding is not working for you have a look at
the
  ar803x_of_init: found PHY node: phy at 0
output. In the case above "phy at 0" is the phy node in the device tree. If
instead the node of your network device is displayed, you have to set
the phydev->node property in your network device driver.

For the fsl_enetc driver this patchset will add it:

changes since v3:
 - add acked-by's, thanks Joe!

changes since v2:
 - rebased onto latest master, esp. #include <dm/device_compat.h>

changes since v1:
 - pull all Vladimirs Oltan's patches and rebase mine onto them
 - fix the CLK_25M settings for the AR8035
 - add two new patches "fix AR8021 PHY ID mask" and "use defines for PHY
   IDs"
 - use the new kernel device tree binding for the AR803x PHYs:

 - add debugging output
