Part of me would assume something like lenovo,leez-p710 So please clarify :-) And also please make sure the decided vendor is part of the vendor-prefixes binding in Documentation/devicestree/bindings/vendor-prefixes.yaml > + - const: rockchip,rk3399 > + > - description: mqmaker MiQi > items: > - const: mqmaker,miqi > diff --git a/arch/arm64/boot/dts/rockchip/Makefile b/arch/arm64/boot/dts/rockchip/Makefile > index daa2c78e22c3..1f18a9392d15 100644 > --- a/arch/arm64/boot/dts/rockchip/Makefile > +++ b/arch/arm64/boot/dts/rockchip/Makefile > @@ -20,6 +20,7 @@ dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-hugsun-x99.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-khadas-edge.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-khadas-edge-captain.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-khadas-edge-v.dtb > +dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-leez-p710.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-nanopc-t4.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-nanopi-m4.dtb > dtb-$(CONFIG_ARCH_ROCKCHIP) += rk3399-nanopi-neo4.dtb > diff --git a/arch/arm64/boot/dts/rockchip/rk3399-leez-p710.dts b/arch/arm64/boot/dts/rockchip/rk3399-leez-p710.dts > new file mode 100644 > index 000000000000..b342f5e8692b > --- /dev/null > +++ b/arch/arm64/boot/dts/rockchip/rk3399-leez-p710.dts > @@ -0,0 +1,635 @@ > +// SPDX-License-Identifier: (GPL-2.0+ OR MIT) > +/* > + * Copyright (c) 2019 Andy Yan <andy.yan@xxxxxxxxx> > + */ > + > +/dts-v1/; > +#include <dt-bindings/input/linux-event-codes.h> > +#include <dt-bindings/pwm/pwm.h> > +#include "rk3399.dtsi" > +#include "rk3399-opp.dtsi" > + > +/ { > + model = "Leez RK3399 P710"; > + compatible = "leez,p710", "rockchip,rk3399"; same comment as above, so maybe: model = "Lenovo Leez RK3399 P710"; compatible = "lenovo,leez-p710", "rockchip,rk3399"; > + > + chosen { > + stdout-path = "serial2:1500000n8"; > + }; > + > + clkin_gmac: external-gmac-clock { > + compatible = "fixed-clock"; > + clock-frequency = <125000000>; > + clock-output-names = "clkin_gmac"; > + #clock-cells = <0>; > + }; > + > + sdio_pwrseq: sdio-pwrseq { > + compatible = "mmc-pwrseq-simple"; > + clocks = <&rk808 1>; > + clock-names = "ext_clock"; > + pinctrl-names = "default"; > + pinctrl-0 = <&wifi_enable_h>; > + reset-gpios = <&gpio0 RK_PB2 GPIO_ACTIVE_LOW>; > + }; > + > + dc5v_adp: dc-5v { > + compatible = "regulator-fixed"; > + regulator-name = "dc5v_adapter"; > + regulator-always-on; > + regulator-boot-on; > + regulator-min-microvolt = <5000000>; > + regulator-max-microvolt = <5000000>; > + }; > + > + vcc5v0_sys: vcc-sys { vcc5v0_sys: vcc5v0-sys ? > + compatible = "regulator-fixed"; > + regulator-name = "vcc5v0_sys"; > + regulator-always-on; > + regulator-boot-on; > + regulator-min-microvolt = <5000000>; > + regulator-max-microvolt = <5000000>; > + vin-supply = <&dc5v_adp>; > + }; > + > + vcc3v3_sys: vcc3v3-sys { > + compatible = "regulator-fixed"; > + regulator-name = "vcc3v3_sys"; > + regulator-always-on; > + regulator-boot-on; > + regulator-min-microvolt = <3300000>; > + regulator-max-microvolt = <3300000>; > + vin-supply = <&vcc5v0_sys>; > + }; > + > + vcc5v0_host: vcc5v0-host-regulator { > + compatible = "regulator-fixed"; > + enable-active-high; > + gpio = <&gpio2 RK_PA2 GPIO_ACTIVE_HIGH>; > + pinctrl-names = "default"; > + pinctrl-0 = <&vcc5v0_host_en>; > + regulator-name = "vcc5v0_host"; > + regulator-always-on; > + vin-supply = <&vcc5v0_sys>; > + }; > + > + vcc_lan: vcc3v3-phy-regulator { > + compatible = "regulator-fixed"; > + regulator-name = "vcc_lan"; > + regulator-always-on; > + regulator-boot-on; > + regulator-min-microvolt = <3300000>; > + regulator-max-microvolt = <3300000>; > + > + regulator-state-mem { > + regulator-off-in-suspend; > + }; > + }; In general, please model an actual regulator-tree and do not copy the unspecific Rockchip vendor tree. These unconnected regulators are a very good indicator that the real power-tree got ignored (missing vin-supply here) I found schematics on https://github.com/leezsbc/resources/wiki/Leez-P710: 链接: https://pan.baidu.com/s/1NPWbuI5csT4zftKUCnRs7g 提取码: rvrh and there the power-tree is described in a complete way. regulator/regulator_summaray in the kernels debugfs should show a nice tree structure starting from the dc-adapter input. Also please use names matching the supply names from the schematics. Same for pinctrl names, please use names as used in the board schematics. > + vdd_log: vdd-log { > + compatible = "pwm-regulator"; > + pwms = <&pwm2 0 25000 1>; > + regulator-name = "vdd_log"; > + regulator-always-on; > + regulator-boot-on; > + regulator-min-microvolt = <800000>; > + regulator-max-microvolt = <1400000>; > + vin-supply = <&vcc5v0_sys>; > + }; > +}; > + > +&cpu_l0 { > + cpu-supply = <&vdd_cpu_l>; > +}; > + > +&cpu_l1 { > + cpu-supply = <&vdd_cpu_l>; > +}; > + > +&cpu_l2 { > + cpu-supply = <&vdd_cpu_l>; > +}; > + > +&cpu_l3 { > + cpu-supply = <&vdd_cpu_l>; > +}; > + > +&cpu_b0 { > + cpu-supply = <&vdd_cpu_b>; > +}; > + > +&cpu_b1 { > + cpu-supply = <&vdd_cpu_b>; > +}; > + > +&emmc_phy { > + status = "okay"; > +}; > + > +&gmac { > + assigned-clocks = <&cru SCLK_RMII_SRC>; > + assigned-clock-parents = <&clkin_gmac>; > + clock_in_out = "input"; > + phy-supply = <&vcc_lan>; > + phy-mode = "rgmii"; > + pinctrl-names = "default"; > + pinctrl-0 = <&rgmii_pins>; > + snps,reset-gpio = <&gpio3 RK_PB7 GPIO_ACTIVE_LOW>; > + snps,reset-active-low; > + snps,reset-delays-us = <0 10000 50000>; > + tx_delay = <0x28>; > + rx_delay = <0x11>; > + status = "okay"; > +}; > + > +&gpu { > + mali-supply = <&vdd_gpu>; > + status = "okay"; > +}; > + > +&hdmi { > + ddc-i2c-bus = <&i2c3>; can this also use the internal i2c inside the dw-hdmi?
