Commit 6d4cd041f0 ("net: phy: at803x: disable delay only for RGMII mode")
exposed an issue on imx DTS files using AR8031/AR8035 PHYs.
The end result is that the boards can no longer obtain an IP address
via UDHCP, for example.
Quoting Andrew Lunn:
"The problem here is, all the DTs were broken since day 0. However,
because the PHY driver was also broken, nobody noticed and it
worked. Now that the PHY driver has been fixed, all the bugs in the
DTs now become an issue"
To fix this problem, the phy-mode property needs to be "rgmii-id", which
has the following meaning as per
Documentation/devicetree/bindings/net/ethernet.txt:
"RGMII with internal RX and TX delays provided by the PHY, the MAC should
not add the RX or TX delays in this case)"
Tested on imx6-sabresd, imx6sx-sdb and imx7d-pico boards with
successfully restored networking.
Based on the initial submission from Steve Twiss for the
imx6qdl-sabresd.

There are two variants of the imx6qdl som: one with Broadcom Wi-Fi and
another with Texas Instruments Wi-Fi. The two Wi-Fi devices require
different DT bindings, so it's necessary to split out the Broadcom
specifics.

Jon and myself feel that "imx6qdl-microsom" is too generic a name for
SolidRun's microsom - some other manufacturer could have their own
microsom. Change the name to the shorter "imx6qdl-sr-som".
