It must be a specific compatible. This is *ONLY* for software models. I really wished people stopped upstreaming junk vendor DTS, but instead take recent, clean DTS and customize it. The approach with junk vendor DTS is always a pain. For everyone. Best regards, Krzysztof

I experimented a bit more and the minimum I need is an empty dt node called ect, otherwise the bootloader will boot loop and we can't boot the kernel [ 2.977870] [E] [BOOT] fdt /ect path not found -1 Apart from a comment indicating that the bootloader requires this empty ect dt node, what other bindings documentation would you like to see?

Fortunately I can remove parameter_address and parameter_size and still boot, so I will remove these in the next version. Thanks, Peter.

It's a remnant from the downstream drivers that support rts-gpio control. I will remove the samsung,pin-val = <1> in the next version. Thanks, Peter

That is correct, it boot loops failing to find the ect node in the bootloader. I did some more investigation and we can actually remove parameter_address and parameter_size properties but the empty ect node needs to be present to boot the kernel. > > > + > > + ext_24_5m: clock-1 { > > + compatible = "fixed-clock"; > > + #clock-cells = <0>; > > + clock-frequency = <24576000>; > > The frequency is probably should be set in board dts file.

Please check > this patch: daeb1c2b50fb ("arm64: dts: exynos: drop incorrectly placed > wakeup interrupts in Exynos850"). If you decide to remove those > interrupts, then bindings doc should be changed too I guess. You were correct. fyi I fixed this in v4. > > > + > > + wakeup-interrupt-controller { > > + compatible = "google,gs101-wakeup-eint"; > > + }; > > + }; > > + > > + /* GPIO_FAR_ALIVE */ > > + pinctrl_1: pinctrl@174e0000 { > > + compatible = "google,gs101-pinctrl"; > > + reg = <0x0 0x174e0000 0x00001000>; > > + interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 46 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 47 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 48 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 49 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 50 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 51 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 52 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 53 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 54 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 55 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 56 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 58 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 59 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 60 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 61 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 62 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 63 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 64 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 65 IRQ_TYPE_LEVEL_HIGH>, > > + <GIC_SPI 66 IRQ_TYPE_LEVEL_HIGH>; > > + > > + wakeup-interrupt-controller { > > + compatible = "google,gs101-wakeup-eint"; > > + }; > > + }; > > + > > + /* GPIO_GSACTRL */ > > + pinctrl_3: pinctrl@17940000 { > > + compatible = "google,gs101-pinctrl"; > > + reg = <0x0 0x17940000 0x00001000>; > > + }; > > + > > + /* GPIO_GSACORE */ > > + pinctrl_2: pinctrl@17a80000 { > > + compatible = "google,gs101-pinctrl"; > > + reg = <0x0 0x17a80000 0x00001000>; > > + }; > > + > > + cmu_top: clock-controller@1e080000 { > > Move it up to other cmus, to make nodes under soc ordered alphabetically?

Google gs101 SoC is ARMv8 mobile SoC found in the Pixel 6, (oriole) Pixel 6a (bluejay) and Pixel 6 pro (raven) mobile phones. It features: * 4xA55 little cluster * 2xA76 Mid cluster * 2xX1 Big cluster This commit adds the basic device tree for gs101 (SoC). Further platform support will be added over time.
