Second Round of Renesas ARM64 Based SoC DT Updates for v4.15
* 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
arm64: dts: renesas: salvator-common: add dr_mode property for USB2.0 channel 0
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".
