A patch from ğarm64: dts: rockchip: add usb typec host support toĞ in state Mainline for linux-kernel

Commit-Message

Jaguar has two type-c ports connected to fusb302 controllers that can work both in host and device mode and can also run in display-port altmode. While these ports can work in dual-role data mode, they do not support powering the device itself as power-sink. This causes issues because the current infrastructure does not cope well with dual-role data without dual-role power. So add the necessary nodes for the type-c controllers as well as enable the relevant core usb nodes. So far host modes works reliably, but device-mode does not. So devicemode needs more investigation. Signed-off-by: Heiko Stuebner <heiko.stuebner@...> Tested-by: Quentin Schulz <quentin.schulz@...>

Patch-Comment

changes in v4: - reword commit message to reflect device-mode not working - rename sbu-pins pinctrl to include _dc - set sbu-dc-pins pinconfig to pull-down. This follows how some dedicated SBU-related ICs do it either internally (TS3USBCA4) or in the block-diagram describe external pull downs (NX20P0407) changes in v3: - more review comments from Quentin (sbu-pin pinctrl, comments) changes in v2: - address review comments from Quentin (comments, pinctrl, sbu-gpios and much more) .../arm64/boot/dts/rockchip/rk3588-jaguar.dts | 218 ++++++++++++++++++ 1 file changed, 218 insertions(+)
