Subject: [PATCH 0/8] Add ethernet support for Qualcomm SA8155p-ADP board

The SA8155p-ADP board supports on-board ethernet (Gibabit Interface),
with support for both RGMII and RMII buses.

This patchset adds the support for the same.

Note that this patchset is based on an earlier sent patchset
for adding PDC controller support on SM8150 (see [1]).

The series can be picked up by 3 different maintainers and e.g. the
network patches seems ready to be merged.

Please facilitate this by sending it in 3 different series (you may
combine clock and dts in one series, as I merge both).

Bjorn

Sure, I will send 3 different series in v2.
