[PATCH v3 1/3] arm64: dts: r8a7795: Add support for R-Car H3 ES2.0

Thu May 11 04:58:52 PDT 2017
Update r8a7795.dtsi so it corresponds to R-Car H3 ES2.0 or later:
- The following devices no longer exist on ES2.0, and are thus removed:
fcpf2, fcpvd3, fcpvi2, fdp1-2, usb3-if1, vspd3, vspi2.
- The DU <-> VSPD topology is different on ES2.0, hence remove the
"compatible" and "vsps" properties from the DU node until the driver
can handle this.
Move support for the ES1.x revision of the R-Car H3 SoC into a
separate file. To avoid duplication, r8a7795-es1.dtsi includes
r8a7795.dtsi, add adds/removes/overrides device nodes and properties
where needed.
Switch r8a7795-salvator-x.dts and r8a7795-h3ulcb.dts from r8a7795.dtsi
to r8a7795-es1.dtsi to preserve compatibility.

While currently r8a7795-es1.dtsi only adds device nodes, removal of
devices nodes and properties can be implemented using the /delete-node/
and /delete-property/ keywords, as shown below:
&soc {
/delete-node/ <name>@<addr>;
};
&<label> {
/delete-property/ <prop>;
};
v3:
- Rebase on top of common Salvator-X board support extraction,
- Remove the "compatible" property from the DU node in r8a7795.dtsi,
in addition to the "vsps" property,
v2:
- Use a separate file for ES1.x instead of for ES2.0, so r8a7795.dtsi
always corresponds to the latest SoC revision,
- Add a dash between SoC part number and revision, for compatibility
with the BSP,
- Enhance the hardware description from basic support to everything
already supported on ES1.x (except for DU due VSP),
- Let r8a7795-es1.dtsi include r8a7795.dtsi.
