Some warnings may be from an existing SoC .dtsi. Or perhaps the warnings are fixed by another series. Ultimately, it is up to the platform maintainer whether these warnings are acceptable or not. No need to reply unless the platform maintainer has comments. If you already ran DT checks and didn't see these error(s), then make sure dt-schema is up to date: pip3 install dtschema --upgrade New warnings running 'make CHECK_DTBS=y allwinner/sun55i-t527-avaota-a1.dtb' for 20241111013033.22793-1-andre.przywara@arm.com: In file included from arch/arm64/boot/dts/allwinner/sun55i-t527-avaota-a1.dts:6: arch/arm64/boot/dts/allwinner/sun55i-a523.dtsi:6:10: fatal error: dt-bindings/clock/sun55i-a523-ccu.h: No such file or directory 6 | #include <dt-bindings/clock/sun55i-a523-ccu.h> | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ compilation terminated. make[3]: *** [scripts/Makefile.dtbs:129: arch/arm64/boot/dts/allwinner/sun55i-t527-avaota-a1.dtb] Error 1 make[2]: *** [scripts/Makefile.build:478: arch/arm64/boot/dts/allwinner] Error 2 make[2]: Target 'arch/arm64/boot/dts/allwinner/sun55i-t527-avaota-a1.dtb' not remade because of errors. make[1]: *** [/home/rob/proj/linux-dt-testing/Makefile:1399: allwinner/sun55i-t527-avaota-a1.dtb] Error 2 make: *** [Makefile:224: __sub-make] Error 2 make: Target 'allwinner/sun55i-t527-avaota-a1.dtb' not remade because of errors.

Hi, this series adds basic DT support for the Allwinner A523 SoC, plus the Avaota-A1 router board using the T527 package variant of that SoC.[1] Functionality-wise it relies on the pinctrl[2] and clock[3] support series, though there is no direct code dependency series to this series (apart from the respective binding patches in the two series'). Most of the patches add DT binding documentation for the most basic peripherals, the vast majority of them actually being already supported, courtesy of identical IP being used. This includes MMC and USB 2.0, so with the above mentioned clock and pinctrl support this gives an already somewhat usable mainline support for this new SoC family. The watchdog is not completely compatible, but is an easy addition, so this bit is included in here as well. The A523 features 8 Arm Cortex-A55 cores, organised in two clusters, clocked separately, with different OPP limits, in some kind of little/LITTLE configuration. The GPU is a Arm Mali G57 MC01, and the chip also features a single PCIe 2.1 lane, sharing a PHY with some USB 3.1 controller - which means only one of the two can be used. The rest of the SoC is the usual soup of multimedia SoC IP, with eDP support and two Gigabit Ethernet MACs among the highlights. The main feature is patch 11/14, which adds the SoC .dtsi. This for now is limited to the parts that are supported and could be tested. At the moment there is no PSCI firmware, even the TF-A port from the BSP does not seem to work for me. That's why the secondary cores have been omitted for now, among other instances of some IP that I couldn't test yet. I plan to add them in one of the next revisions. The last patch adds basic support for the Avaota-A1 router board, designed by YuzukiHD, with some boards now built by Pine64. The mainline firmware side in general is somewhat lacking still: I have basic U-Boot support working (including MMC and USB), although still without DRAM support. This is for now covered by some binary blob found in the (otherwise Open Source) Syterkit firmware, which also provides the BSP versions of TF-A and the required (RISC-V) management core firmware. Fortunately we have indications that DRAM support is not that tricky, as the IP blocks are very similar to already supported, and dev boards are on their way to the right people. Meanwhile I would like people to have a look at those DT bits here. Please compare them to the available user manual, and test them if you have access to hardware. Based on v6.12-rc1. I pushed a branch with all the three series combined here: https://github.com/apritzel/linux/commits/a523-v1/ Cheers, Andre [1] https://linux-sunxi.org/A523#Family_of_sun55iw3 [2] https://lore.kernel.org/linux-sunxi/20241111005750.13071-1-andre.przywara@arm.com/T/#t [3] https://lore.kernel.org/linux-sunxi/20241111004722.10130-1-andre.przywara@arm.com/T/#t Andre Przywara (14): dt-bindings: mmc: sunxi: Simplify compatible string listing dt-bindings: mmc: sunxi: add compatible strings for Allwinner A523 dt-bindings: watchdog: sunxi: add Allwinner A523 compatible string watchdog: sunxi_wdt: Add support for Allwinner A523 dt-bindings: i2c: mv64xxx: Add Allwinner A523 compatible string dt-bindings: irq: sun7i-nmi: document the Allwinner A523 NMI controller dt-bindings: phy: document Allwinner A523 USB-2.0 PHY dt-bindings: usb: sunxi-musb: add Allwinner A523 compatible string dt-bindings: usb: add A523 compatible string for EHCI and OCHI dt-bindings: rtc: sun6i: Add Allwinner A523 support arm64: dts: allwinner: Add Allwinner A523 .dtsi file dt-bindings: vendor-prefixes: Add YuzukiHD name dt-bindings: arm: sunxi: Add Avaota A1 board arm64: dts: allwinner: a523: add Avaota-A1 router support .../devicetree/bindings/arm/sunxi.yaml | 5 + .../bindings/i2c/marvell,mv64xxx-i2c.yaml | 1 + .../allwinner,sun7i-a20-sc-nmi.yaml | 1 + .../bindings/mmc/allwinner,sun4i-a10-mmc.yaml | 40 +- .../phy/allwinner,sun50i-a64-usb-phy.yaml | 10 +- .../bindings/rtc/allwinner,sun6i-a31-rtc.yaml | 4 +- .../usb/allwinner,sun4i-a10-musb.yaml | 1 + .../devicetree/bindings/usb/generic-ehci.yaml | 1 + .../devicetree/bindings/usb/generic-ohci.yaml | 1 + .../devicetree/bindings/vendor-prefixes.yaml | 2 + .../watchdog/allwinner,sun4i-a10-wdt.yaml | 2 + arch/arm64/boot/dts/allwinner/Makefile | 1 + .../arm64/boot/dts/allwinner/sun55i-a523.dtsi | 386 ++++++++++++++++++ .../dts/allwinner/sun55i-t527-avaota-a1.dts | 311 ++++++++++++++ drivers/watchdog/sunxi_wdt.c | 11 + 15 files changed, 751 insertions(+), 26 deletions(-) create mode 100644 arch/arm64/boot/dts/allwinner/sun55i-a523.dtsi create mode 100644 arch/arm64/boot/dts/allwinner/sun55i-t527-avaota-a1.dts
