This is actually added by an earlier patch within this series (5/7), but since it isn't used anywhere yet, might as well drop it for now, "mediatek,mtu3" by itself works. > > + usb_host: usb@11200000 { > > + compatible = "mediatek,mt8365-xhci", "mediatek,mtk-xhci"; > > Same here.

Can add it of course (but then mediatek,mt8365-uart and friends should probably stay as well). I'll post a new revision adding it back (along with the binding description) and add the binding description for mt8365-uart as well (getting it to the same place mediatek,mt8365-mtu3 and mediatek,mt8365-xhci are now). Let me know if you'd prefer a variant that drops mediatek,mt8365-uart, mediatek,mt8365-mtu3, mediatek,mt8365-xhci and doesn't bring back mediatek,mt8365-systimer -- either one works for me, the fallbacks are sufficient to make it work. ttyl bero
This adds minimal support for the MediaTek 8365 SOC and the EVK reference board, allowing the board to boot to initramfs with serial port I/O. v7: - Update GIC information in mt8365.dtsi (thanks to Marc Zyngier for pointing out the problem) - Adjust the timer to match the updated GIC information v6: - Add systimer in mt8365.dtsi - Add I/D caches and L2 cache details in mt8365.dtsi - Move bl31_secmon_reserved from mt8365.dtsi to mt8365-evk.dts - Fix inconsistent indentation in mt8365-pinctrl example - Further mt8365.dtsi cleanups - Submit to additional maintainers spotted by get_maintainer.pl v5: - Reorder top-level entries in mediatek,mt8365-pinctrl.yaml to match example-schema - Use consistent quotes v4: - Remove pins-are-numbered references that have been holding things up now that the patches removing it from dt-bindings have landed in linux-next v3: - Remove a number of components that are not yet supported (they will come back alongside the corresponding drivers) - Address issues found by dt_binding_check (mostly fixing pinctrl bindings) - Address issues pointed out in comments - Reorder patches v2: - Add missing dt-bindings documentation - Small cleanups addressing issues in v1 pointed out by Krzysztof Kozlowski Bernhard Rosenkränzer (4): dt-bindings: arm64: dts: mediatek: Add mt8365-evk board dt-bindings: irq: mtk, sysirq: add support for mt8365 dt-bindings: mfd: syscon: Add mt8365-syscfg dt-bindings: pinctrl: add bindings for Mediatek MT8365 SoC Fabien Parent (3): dt-bindings: usb: mediatek,mtu3: add MT8365 SoC bindings dt-bindings: usb: mediatek,mtk-xhci: add MT8365 SoC bindings arm64: dts: mediatek: Initial mt8365-evk support .../devicetree/bindings/arm/mediatek.yaml | 4 + .../interrupt-controller/mediatek,sysirq.txt | 1 + .../devicetree/bindings/mfd/syscon.yaml | 1 + .../pinctrl/mediatek,mt8365-pinctrl.yaml | 197 +++++++++ .../bindings/usb/mediatek,mtk-xhci.yaml | 1 + .../bindings/usb/mediatek,mtu3.yaml | 1 + arch/arm64/boot/dts/mediatek/Makefile | 1 + arch/arm64/boot/dts/mediatek/mt8365-evk.dts | 169 ++++++++ arch/arm64/boot/dts/mediatek/mt8365.dtsi | 378 ++++++++++++++++++ 9 files changed, 753 insertions(+) create mode 100644 Documentation/devicetree/bindings/pinctrl/mediatek,mt8365-pinctrl.yaml create mode 100644 arch/arm64/boot/dts/mediatek/mt8365-evk.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8365.dtsi
