Squashed backup commit (no shallow-clone history issues) of xiaomi-mt6833-dev/kernel_xiaomi_mt6833 (lineage-23.2 branch, upstream commit 9eece662e) plus all fixes applied to get everpal_defconfig building clean against a modern (GCC 15.2.0) toolchain -- see the previous commit message on the lineage-23.2 branch (also in this repo history is not available here since this is a squashed snapshot; full incremental history lives in the local DL380 checkout and the upstream GitHub remote).

* Renesas R-Car generation 3 USB 2.0 PHY
|
|
|
|
This file provides information on what the device node for the R-Car generation
|
|
3 USB 2.0 PHY contains.
|
|
|
|
Required properties:
|
|
- compatible: "renesas,usb2-phy-r8a7795" if the device is a part of an R8A7795
|
|
SoC.
|
|
"renesas,usb2-phy-r8a7796" if the device is a part of an R8A7796
|
|
SoC.
|
|
"renesas,rcar-gen3-usb2-phy" for a generic R-Car Gen3 compatible device.
|
|
|
|
When compatible with the generic version, nodes must list the
|
|
SoC-specific version corresponding to the platform first
|
|
followed by the generic version.
|
|
|
|
- reg: offset and length of the partial USB 2.0 Host register block.
|
|
- clocks: clock phandle and specifier pair(s).
|
|
- #phy-cells: see phy-bindings.txt in the same directory, must be <0>.
|
|
|
|
Optional properties:
|
|
To use a USB channel where USB 2.0 Host and HSUSB (USB 2.0 Peripheral) are
|
|
combined, the device tree node should set interrupt properties to use the
|
|
channel as USB OTG:
|
|
- interrupts: interrupt specifier for the PHY.
|
|
- vbus-supply: Phandle to a regulator that provides power to the VBUS. This
|
|
regulator will be managed during the PHY power on/off sequence.
|
|
|
|
Example (R-Car H3):
|
|
|
|
usb-phy@ee080200 {
|
|
compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
|
|
reg = <0 0xee080200 0 0x700>;
|
|
interrupts = <GIC_SPI 108 IRQ_TYPE_LEVEL_HIGH>;
|
|
clocks = <&cpg CPG_MOD 703>;
|
|
};
|
|
|
|
usb-phy@ee0a0200 {
|
|
compatible = "renesas,usb2-phy-r8a7795", "renesas,rcar-gen3-usb2-phy";
|
|
reg = <0 0xee0a0200 0 0x700>;
|
|
clocks = <&cpg CPG_MOD 702>;
|
|
};
