Historically DSI PHY device tree nodes used the dsi-phy@ names. Replace

Dmitry Baryshkov (9):
   ARM: dts: qcom-apq8064: change DSI PHY node name to generic one

dsi-phy is similar to other generic names (usb-phy, ethernet-phy) [1] so
it could stay. Is there particular need for this, like coming from DT
schema?

No, there is no requirement from the DT schema. However:
1) The resent qcom DT files already use just phy@ for most of PHY nodes
2) The recommended list mentions usb-phy/ethernet-phy, but not <anything>-phy, so I'd think that those two are mostly for backwards compatibility. 3) I liked the example of sc7280 which switched all MDSS PHYs to just phy@ (this includes DSI PHY, eDP PHY and, by extension, the HDMI PHY).
