The USBDP PHY offers USB3 dual-role and DisplayPort. The driver and bindings being upstreamed contains the DP parts, but only USB3 has been tested by me (upstream does not yet have a DRM DP bridge driver for this platform). What has been tested: - USB3 Type A ports on Rock 5A, Rock 5B, EVB1 - USB Type C port on EVB1 in Host mode I did not yet include a patch to enable the Type-C from the Rock 5B, since that requires enabling proper support for the fusb302. Since the system is usually supplied via USB-C and without any battery backup, this easily results in system reset when the power-delivery negotiation happens. As this issue is independent from the USBDP PHY, I skipped enabling that port on Rock 5B for now. You can find a branch with these patches here: https://gitlab.collabora.com/hardware-enablement/rockchip-3588/linux/-/commits/rk3588-usbdp Changes since PATCHv2: * https://lore.kernel.org/all/20240213163609.44930-1-sebastian.reichel@collabora.com/ * Drop patch 1+2 (GRF DT bindings got merged by Heiko Stübner) * USBDP PHY DT binding: more spelling fixes * USBDP PHY DT binding: add Reviewed-by from Conor Dooley * USBDP PHY DT binding: specify 3 as maximum value for rockchip,dp-lane-mux items * all patches: remove child nodes for usb3-port and dp-port and use PHY cell instead * USBDP PHY driver: drop some header includes * USBDP PHY driver: rework rk_udphy_grfreg_write to use FIELD_PREP_CONST * USBDP PHY driver: add newline after break; in switch cases * USBDP PHY driver: make some functions void Changes since PATCHv1: * https://lore.kernel.org/all/20240209181831.104687-1-sebastian.reichel@collabora.com/ * VO GRF DT binding: Collect Acked-by from Conor Dooley * USB3 syscon DT binding: Collect Acked-by from Conor Dooley * USBDP PHY DT binding: fix spelling * USBDP PHY DT binding: add maxItems: 1 to gpios * USBDP PHY driver: use rk_udphy_ prefix everywhere * USBDP PHY DT addition: fix nodenames and property order * USBDP PHY DT addition: fix position of the GRF nodes * add new patches fixing existing USB2 PHY nodenames/property order Not changed: * rockchip,dp-lane-mux: Why "mux" and not "map"? - This is about muxing DP lanes vs USB3 lanes. I kept mux instead of map, since that's used downstream and there does not seem to be a good reason to diverge? -- Sebastian Sebastian Reichel (10): dt-bindings: phy: add rockchip usbdp combo phy document phy: rockchip: add usbdp combo phy driver arm64: defconfig: enable Rockchip Samsung USBDP PHY arm64: dts: rockchip: fix usb2phy nodename for rk3588 arm64: dts: rockchip: reorder usb2phy properties for rk3588 arm64: dts: rockchip: add USBDP phys on rk3588 arm64: dts: rockchip: add USB3 DRD controllers on rk3588 arm64: dts: rockchip: add USB3 to rk3588-evb1 arm64: dts: rockchip: add upper USB3 port to rock-5a arm64: dts: rockchip: add lower USB3 port to rock-5b .../bindings/phy/phy-rockchip-usbdp.yaml | 148 ++ .../boot/dts/rockchip/rk3588-evb1-v10.dts | 143 ++ .../boot/dts/rockchip/rk3588-rock-5b.dts | 17 + arch/arm64/boot/dts/rockchip/rk3588.dtsi | 72 + .../boot/dts/rockchip/rk3588s-rock-5a.dts | 18 + arch/arm64/boot/dts/rockchip/rk3588s.dtsi | 105 +- arch/arm64/configs/defconfig | 1 + drivers/phy/rockchip/Kconfig | 12 + drivers/phy/rockchip/Makefile | 1 + drivers/phy/rockchip/phy-rockchip-usbdp.c | 1612 +++++++++++++++++ 10 files changed, 2119 insertions(+), 10 deletions(-) create mode 100644 Documentation/devicetree/bindings/phy/phy-rockchip-usbdp.yaml create mode 100644 drivers/phy/rockchip/phy-rockchip-usbdp.c
