Merge branch 'net-phy-at803x-device-tree-binding'

Michael Walle says:

====================
net: phy: at803x device tree binding

Adds a device tree binding to configure the clock and the RGMII voltage.

Changes since v1:
 - rebased to latest net-next
 - renamed "Atheros" to "Qualcomm Atheros"
 - add a new patch to remove config_init() from AR9331

Changes since the RFC:
 - renamed the Kconfig entry to "Qualcomm Atheros.." and reordered the
   item
 - renamed the prefix from atheros to qca
 - use the correct name AR803x (instead of AT803x) in new files and
   dt-bindings.
 - listed the PHY maintainers in the new schema. Hopefully, thats ok.
 - fixed a typo in the bindings schema
 - run dtb_checks and dt_binding_check and fixed the schema
 - dropped the rgmii-io-1v8 property; instead provide two regulators vddh
   and vddio, add one consumer vddio-supply
 - fix the clock settings for the AR8030/AR8035
 - only the AR8031 supports chaning the LDO and the PLL mode in software.
   Check if we have the correct PHY.
 - new patch to mention the AR8033 which is the same as the AR8031 just
   without PTP support
 - new patch which corrects any displayed PHY names and comments. Be
   consistent.
