[PATCH 12/13] phy: qcom-qmp-usb: restructure PHY creation

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



In preparation for supporting devicetree bindings which do not use a
child node, move the PHY creation to probe() proper and parse the serdes
and dp_com resources in what is now the legacy devicetree helper.
