Pull "Second Round of Renesas ARM64 Based SoC DT Updates for v4.15" from Simon Horman:

* r8a7795 (H3) and r8a7796 (M3-W) SoCs
  - Use R-Car Gen 3 fallback compat string for GPIO

    Simon Horman says "Use newly added R-Car GPIO Gen 1, 2 and 3 fallback
    compat strings in peace of now deprecated non-generation specific R-Car
    GPIO fallback compat string in the DT of Renesas ARM and arm64 based
    SoCs.

* r8a7795 (H3) and r8a7796 (M3-W) Salvator boards
  - Add dr_mode property for USB2.0 channel 0

    Shimoda-san says "Since Salvator-X[S] have a USB2.0 dual-role channel
    (CN9), this patch
    adds dr_mode property for USB2.0 channel 0 (EHCI/OHCI and HS-USB)
    as "otg".

    Using dual-role channel (or not) is related to the type of USB receptor
    on board specification. So, I added the property into the
    salvator-common.dtsi."

  - Add pfc node for USB3.0 channel 0

    Shimoda-san says "Since a R-Car Gen3 bootloader enables the PFC of
    USB3.0 channel 0, the USB3.0 host controller works without this setting
    on the kernel.  But, this setting should have salvator-common.dtsi. So,
    this patch adds the pfc node for USB3.0 channel 0."

* r8a7795 (H3) and r8a7796 (M3-W) Salvator and ULCB boards
  - Correct audio_clkout

    Morimoto-san says ""audio_clkout" is dummy clock of <&rcar_sound 0> to
    avoid clock loop which invites probe conflct. Thus <&rcar_sound 0> and
    "audio_clkout" should be same value."

* r8a7795 (H3) and r8a7796 (M3-W) Salvator and ULCB, and
  r8a77995 (D3) Draak boards
  - Drop "avb_phy_int" from avb_pins

    Shimoda-san says "Since the Ethernet AVB driver doesn't support
    AVB_PHY_INT handling and it will be handled by a phy driver as a gpio
    pin, this patch removes the "avb_phy_int" from the avb_pins node."

* r8a77995 (D3) Draak board
  - Enable PWM channels

    Shimoda-san says "Each channel connects to LTC2644 for brightness
    control."

* r8a77970 (V3M) Eagle and ULCB Kingfisher boards
  - Add initial device tree support
