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, and adds device nodes and properties where needed. Note that 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>; }; Switch r8a7795-salvator-x.dts and r8a7795-h3ulcb.dts from r8a7795.dtsi to r8a7795-es1.dtsi to preserve compatibility. Signed-off-by: Geert Uytterhoeven <geert+renesas@glider.be> --- v4: - Remove "/remove/overrides", as r8a7795-es1.dtsi does additions only, - Move node and property deletion guidelines above the scissors, - Rebase on top of r8a7795 HDMI support, 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. --- arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi | 84 ++++++++++++++++++++++ arch/arm64/boot/dts/renesas/r8a7795-h3ulcb.dts | 4 +- arch/arm64/boot/dts/renesas/r8a7795-salvator-x.dts | 4 +- arch/arm64/boot/dts/renesas/r8a7795.dtsi | 71 +----------------- 4 files changed, 89 insertions(+), 74 deletions(-) create mode 100644 arch/arm64/boot/dts/renesas/r8a7795-es1.dtsi
