While this makes things better, it's not correct. The i2c2 bus does not use the trackpad pin. I would believe a better way is to have a node that holds both trackpads and claims the pin for both at once. And that node not being the i2c bus as there could be more devices on the bus and the pin would be taken regardless of any trackpad probing , which is not right. Another option is to disable parallel probing for the trackpads, such that when one fails to probe, the pin is released and can be taken by the other one. > + clock-frequency = <400000>; > + i2c-scl-internal-delay-ns = <10000>; > + status = "okay"; > + > + trackpad@15 { > + compatible = "elan,ekth3000"; > + reg = <0x15>; > + interrupts-extended = <&pio 11 IRQ_TYPE_LEVEL_LOW>; > + vcc-supply = <&pp3300_s3>; > + wakeup-source; > + }; > +}; > + > +&i2c3 { > + pinctrl-names = "default"; > + pinctrl-0 = <&i2c3_pins>; > + clock-frequency = <100000>; > + status = "okay"; > + > + it6505dptx: dp-bridge@5c { > + compatible = "ite,it6505"; > + reg = <0x5c>; > + interrupts-extended = <&pio 8 IRQ_TYPE_LEVEL_LOW>; > + ovdd-supply = <&mt6366_vsim2_reg>; > + pwr18-supply = <&pp1800_dpbrdg_dx>; > + reset-gpios = <&pio 177 GPIO_ACTIVE_HIGH>; > + pinctrl-names = "default"; > + pinctrl-0 = <&it6505_pins>; > + > + #address-cells = <1>; > + #size-cells = <0>; > + #sound-dai-cells = <0>; > + > + ports { > + #address-cells = <1>; > + #size-cells = <0>; > + > + port@0 { > + reg = <0>; > + > + it6505_in: endpoint { > + link-frequencies = /bits/ 64 <150000000>; > + remote-endpoint = <&dpi_out>; > + }; > + }; > + > + port@1 { > + reg = <1>; > + }; > + }; > + }; > +}; > + > +&i2c5 { > + pinctrl-names = "default"; > + pinctrl-0 = <&i2c5_pins>; > + status = "okay"; > + > + rt5682s: codec@1a { > + compatible = "realtek,rt5682s"; > + reg = <0x1a>; > + interrupts-extended = <&pio 17 IRQ_TYPE_EDGE_BOTH>; > + AVDD-supply = <&mt6366_vio18_reg>; > + DBVDD-supply = <&mt6366_vio18_reg>; > + LDO1-IN-supply = <&mt6366_vio18_reg>; > + MICVDD-supply = <&pp3300_z2>; > + realtek,jd-src = <1>; > + #sound-dai-cells = <1>; > + }; > +}; > + > +&mfg0 { > + domain-supply = <&mt6366_vsram_gpu_reg>; > +}; > + > +&mfg1 { > + domain-supply = <&mt6366_vgpu_reg>; > +}; > + > +&mipi_tx0 { > + status = "okay"; > +}; > + > +&mmc0 { > + pinctrl-names = "default", "state_uhs"; > + pinctrl-0 = <&mmc0_pins_default>; > + pinctrl-1 = <&mmc0_pins_uhs>; > + bus-width = <8>; > + max-frequency = <200000000>; > + non-removable; > + cap-mmc-highspeed; > + mmc-hs200-1_8v; > + mmc-hs400-1_8v; > + supports-cqe; > + no-sd; > + no-sdio; > + cap-mmc-hw-reset; > + hs400-ds-delay = <0x11814>; > + mediatek,hs400-ds-dly3 = <0x14>; > + vmmc-supply = <&mt6366_vemc_reg>; > + vqmmc-supply = <&mt6366_vio18_reg>; > + status = "okay"; > +}; > + > +&mmc1 { > + pinctrl-names = "default", "state_uhs", "state_eint"; > + pinctrl-0 = <&mmc1_pins_default>; > + pinctrl-1 = <&mmc1_pins_uhs>; > + pinctrl-2 = <&mmc1_pins_eint>; > + /delete-property/ interrupts; > + interrupt-names = "msdc", "sdio_wakeup"; > + interrupts-extended = <&gic GIC_SPI 101 IRQ_TYPE_LEVEL_HIGH 0>, > + <&pio 87 IRQ_TYPE_LEVEL_LOW>; > + bus-width = <4>; > + max-frequency = <200000000>; > + cap-sd-highspeed; > + sd-uhs-sdr104; > + sd-uhs-sdr50; > + keep-power-in-suspend; > + wakeup-source; > + cap-sdio-irq; > + no-mmc; > + no-sd; > + non-removable; > + vmmc-supply = <&pp3300_s3>; > + vqmmc-supply = <&mt6366_vio18_reg>; > + mmc-pwrseq = <&wifi_pwrseq>; > + status = "okay"; > + #address-cells = <1>; > + #size-cells = <0>; > + > + bluetooth@2 { > + compatible = "mediatek,mt7921s-bluetooth"; > + reg = <2>; > + pinctrl-names = "default"; > + pinctrl-0 = <&bt_pins_reset>; > + reset-gpios = <&pio 155 GPIO_ACTIVE_LOW>; > + }; > +}; > + > +&nor_flash { > + pinctrl-names = "default"; > + pinctrl-0 = <&nor_pins_default>; > + assigned-clock-parents = <&topckgen CLK_TOP_MAINPLL_D7_D4>; > + status = "okay"; > + #address-cells = <1>; > + #size-cells = <0>; > + > + flash@0 { > + compatible = "jedec,spi-nor"; > + reg = <0>; > + spi-max-frequency = <39000000>; > + }; > +}; > + > +&pio { > + /* 185 lines */ > + gpio-line-names = "TP", > + "TP", > + "TP", > + "I2S0_HP_DI", > + "I2S3_DP_SPKR_DO", > + "SAR_INT_ODL", > + "BT_WAKE_AP_ODL", > + "WIFI_INT_ODL", > + "DPBRDG_INT_ODL", > + "EDPBRDG_INT_ODL", > + "EC_AP_HPD_OD", > + "TCHPAD_INT_ODL", > + "TCHSCR_INT_1V8_ODL", > + "EC_AP_INT_ODL", > + "EC_IN_RW_ODL", > + "GSC_AP_INT_ODL", > + /* AP_FLASH_WP_L is crossystem ABI.

Standard/common properties (defined by common bindings, e.g. without vendor-prefixes) 5. Vendor-specific properties 6. status (if applicable) 7. Child nodes, where each node is preceded with a blank line The "status" property is by default "okay", thus it can be omitted. The above-described ordering follows this approach: 1. Most important properties start the node: compatible then bus addressing to match unit address. 2. Each node will have common properties in similar place. 3. Status is the last information to annotate that device node is or is not finished (board resources are needed). #io-channel-cells goes after `reg` (same for the other instances) :-) > + }; > +}; > + > +&pio { > + i2c4_pins: i2c4-pins { > + pins-bus { > + pinmux = <PINMUX_GPIO136__FUNC_SDA4>, > + <PINMUX_GPIO135__FUNC_SCL4>; > + bias-disable; > + drive-strength = <4>; > + input-enable; > + }; > + }; > + > + ps8640_pins: ps8640-pins { > + pins-pwrdn-rst { > + pinmux = <PINMUX_GPIO96__FUNC_GPIO96>, > + <PINMUX_GPIO98__FUNC_GPIO98>; > + output-low; > + }; > + }; > + > + sar_sensor_pins: sar-sensor-pins { > + pins-irq { > + pinmux = <PINMUX_GPIO5__FUNC_GPIO5>; > + input-enable; > + bias-pull-up; > + }; > + }; > +}; > diff --git a/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327681.dts b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327681.dts > new file mode 100644 > index 000000000000..9bb64353ca65 > --- /dev/null > +++ b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327681.dts > @@ -0,0 +1,57 @@ > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > +/* > + * Copyright 2022 Google LLC > + */ > + > +/dts-v1/; > +#include "mt8186-corsola-krabby.dtsi" > + > +/ { > + model = "Google Tentacool board"; > + compatible = "google,tentacruel-sku327681", "google,tentacruel", "mediatek,mt8186"; > + chassis-type = "laptop"; > +}; > + > +/* Tentacool omits the pen. */ > +&gpio_keys { > + status = "disabled"; > +}; > + > +/* Tentacool omits the touchscreen; nothing else is on i2c1. */ > +&i2c1 { > + status = "disabled"; > +}; > + > +&keyboard_controller { > + function-row-physmap = < > + MATRIX_KEY(0x00, 0x02, 0) /* T1 */ > + MATRIX_KEY(0x03, 0x02, 0) /* T2 */ > + MATRIX_KEY(0x02, 0x02, 0) /* T3 */ > + MATRIX_KEY(0x01, 0x02, 0) /* T4 */ > + MATRIX_KEY(0x03, 0x04, 0) /* T5 */ > + MATRIX_KEY(0x02, 0x04, 0) /* T6 */ > + MATRIX_KEY(0x01, 0x04, 0) /* T7 */ > + MATRIX_KEY(0x02, 0x09, 0) /* T8 */ > + MATRIX_KEY(0x01, 0x09, 0) /* T9 */ > + MATRIX_KEY(0x00, 0x04, 0) /* T10 */ > + >; > + > + linux,keymap = < > + MATRIX_KEY(0x00, 0x02, KEY_BACK) > + MATRIX_KEY(0x03, 0x02, KEY_REFRESH) > + MATRIX_KEY(0x02, 0x02, KEY_ZOOM) > + MATRIX_KEY(0x01, 0x02, KEY_SCALE) > + MATRIX_KEY(0x03, 0x04, KEY_SYSRQ) > + MATRIX_KEY(0x02, 0x04, KEY_BRIGHTNESSDOWN) > + MATRIX_KEY(0x01, 0x04, KEY_BRIGHTNESSUP) > + MATRIX_KEY(0x02, 0x09, KEY_MUTE) > + MATRIX_KEY(0x01, 0x09, KEY_VOLUMEDOWN) > + MATRIX_KEY(0x00, 0x04, KEY_VOLUMEUP) > + CROS_STD_MAIN_KEYMAP > + >; > +}; > + > +/* Tentacool omits the touchscreen. */ > +&touchscreen { > + status = "disabled"; > +}; > diff --git a/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327683.dts b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327683.dts > new file mode 100644 > index 000000000000..c3ae6f9616c8 > --- /dev/null > +++ b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacool-sku327683.dts > @@ -0,0 +1,24 @@ > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > +/* > + * Copyright 2023 Google LLC > + */ > + > +#include "mt8186-corsola-tentacool-sku327681.dts" > + > +/ { > + compatible = "google,tentacruel-sku327683", "google,tentacruel", "mediatek,mt8186"; > +}; > + > +/* This variant replaces only the trackpad controller. */ > +&i2c2 { > + /delete-node/ trackpad@15; Why are you deleting the trackpad@15 node?

After all, since we *want to* use the Xtensa DSP for audio, without it booted sound won't work *anyway*.... so having the firmware in place can also be seen as a direct dependency of the entire audio functionality.

Hence I believe it should live in the base .dtsi. The delete-node makes it much less likely to have any lingering properties. These are not nodes that just differ in compatible strings like DSI panels. They have incompatible bindings. For example, elan,ekth3000 uses "vcc-supply", while "hid-over-i2c" uses "vdd-supply". And going back to my previous argument, the base design used one specific model which is carried over to all the other models. Suppose I add a phandle to the original trackpad, and do /delete-node/ &trackpad; Would that be better? > other dts: > > &trackpad_a { > compatible = "hid-over-i2c"; > }; > > > + > > + trackpad@15 { > > + compatible = "hid-over-i2c"; > > + reg = <0x15>; > > + interrupts-extended = <&pio 11 IRQ_TYPE_LEVEL_LOW>; > > + hid-descr-addr = <0x0001>; > > + vdd-supply = <&pp3300_s3>; > > + wakeup-source; > > + }; > > +}; > > diff --git a/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262144.dts b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262144.dts > > new file mode 100644 > > index 000000000000..26d3451a5e47 > > --- /dev/null > > +++ b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262144.dts > > @@ -0,0 +1,44 @@ > > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > > +/* > > + * Copyright 2022 Google LLC > > + */ > > + > > +/dts-v1/; > > +#include "mt8186-corsola-krabby.dtsi" > > + > > +/ { > > + model = "Google Tentacruel board"; > > + compatible = "google,tentacruel-sku262147", "google,tentacruel-sku262146", > > + "google,tentacruel-sku262145", "google,tentacruel-sku262144", > > + "google,tentacruel", "mediatek,mt8186"; > > + chassis-type = "convertible"; > > +}; > > + > > +&keyboard_controller { > > + function-row-physmap = < > > + MATRIX_KEY(0x00, 0x02, 0) /* T1 */ > > + MATRIX_KEY(0x03, 0x02, 0) /* T2 */ > > + MATRIX_KEY(0x02, 0x02, 0) /* T3 */ > > + MATRIX_KEY(0x01, 0x02, 0) /* T4 */ > > + MATRIX_KEY(0x03, 0x04, 0) /* T5 */ > > + MATRIX_KEY(0x02, 0x04, 0) /* T6 */ > > + MATRIX_KEY(0x01, 0x04, 0) /* T7 */ > > + MATRIX_KEY(0x02, 0x09, 0) /* T8 */ > > + MATRIX_KEY(0x01, 0x09, 0) /* T9 */ > > + MATRIX_KEY(0x00, 0x04, 0) /* T10 */ > > + >; > > + > > + linux,keymap = < > > + MATRIX_KEY(0x00, 0x02, KEY_BACK) > > + MATRIX_KEY(0x03, 0x02, KEY_REFRESH) > > + MATRIX_KEY(0x02, 0x02, KEY_ZOOM) > > + MATRIX_KEY(0x01, 0x02, KEY_SCALE) > > + MATRIX_KEY(0x03, 0x04, KEY_SYSRQ) > > + MATRIX_KEY(0x02, 0x04, KEY_BRIGHTNESSDOWN) > > + MATRIX_KEY(0x01, 0x04, KEY_BRIGHTNESSUP) > > + MATRIX_KEY(0x02, 0x09, KEY_MUTE) > > + MATRIX_KEY(0x01, 0x09, KEY_VOLUMEDOWN) > > + MATRIX_KEY(0x00, 0x04, KEY_VOLUMEUP) > > + CROS_STD_MAIN_KEYMAP > > + >; > > +}; > > diff --git a/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262148.dts b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262148.dts > > new file mode 100644 > > index 000000000000..447b57b12b41 > > --- /dev/null > > +++ b/arch/arm64/boot/dts/mediatek/mt8186-corsola-tentacruel-sku262148.dts > > @@ -0,0 +1,26 @@ > > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > > +/* > > + * Copyright 2023 Google LLC > > + */ > > + > > +#include "mt8186-corsola-tentacruel-sku262144.dts" > > + > > +/ { > > + compatible = "google,tentacruel-sku262151", "google,tentacruel-sku262150", > > + "google,tentacruel-sku262149", "google,tentacruel-sku262148", > > + "google,tentacruel", "mediatek,mt8186"; > > +}; > > + > > +/* This variant replaces only the trackpad controller. */ > > +&i2c2 { > > + /delete-node/ trackpad@15; > > + > > + trackpad@15 { > > + compatible = "hid-over-i2c"; > > + reg = <0x15>; > > + interrupts-extended = <&pio 11 IRQ_TYPE_LEVEL_LOW>; > > + hid-descr-addr = <0x0001>; > > + vdd-supply = <&pp3300_s3>; > > + wakeup-source; > > + }; > > +}; > > diff --git a/arch/arm64/boot/dts/mediatek/mt8186-corsola.dtsi b/arch/arm64/boot/dts/mediatek/mt8186-corsola.dtsi > > new file mode 100644 > > index 000000000000..8726b2916ef1 > > --- /dev/null > > +++ b/arch/arm64/boot/dts/mediatek/mt8186-corsola.dtsi > > @@ -0,0 +1,1719 @@ > > +// SPDX-License-Identifier: (GPL-2.0 OR MIT) > > +/* > > + * Copyright (C) 2022 MediaTek Inc. > > + */ > > +/dts-v1/; > > +#include "mt8186.dtsi" > > +#include <dt-bindings/pinctrl/mt8186-pinfunc.h> > > +#include <dt-bindings/gpio/gpio.h> > > +#include <dt-bindings/input/input.h> > > +#include <dt-bindings/input/gpio-keys.h> > > +#include <dt-bindings/regulator/mediatek,mt6397-regulator.h> > > + > > +/ { > > + aliases { > > + i2c0 = &i2c0; > > + i2c1 = &i2c1; > > + i2c2 = &i2c2; > > + i2c3 = &i2c3; > > + i2c5 = &i2c5; > > + mmc0 = &mmc0; > > + mmc1 = &mmc1; > > + serial0 = &uart0; > > + }; > > + > > + chosen { > > + stdout-path = "serial0:115200n8"; > > + }; > > + > > + memory@40000000 { > > + device_type = "memory"; > > + /* The size should be filled in by the bootloader. */ > > + reg = <0 0x40000000 0 0>; > > + }; > > + > > + backlight_lcd0: backlight-lcd0 { > > + compatible = "pwm-backlight"; > > + pwms = <&pwm0 0 500000>; > > + power-supply = <&ppvar_sys>; > > + enable-gpios = <&pio 152 0>; > > + brightness-levels = <0 1023>; > > + num-interpolated-steps = <1023>; > > + default-brightness-level = <576>; > > + }; > > + > > + btsco: bt-sco { > > Do you really need the phandle to bt-sco? No. But the sound node probably should be referencing it and the dmic node via DT instead of hardcoding the DAI and codec names in the machine driver.

Hi everyone, This is v3 of the MT8186 Chromebook device tree series. Changes since v2: - Picked up Conor's ack - Renamed remaining "touchpad" nodes to "trackpad" - Dropped pinctrl from tentacruel/tentacool second source trackpad Changes since v1: - Reorder SKU numbers in descending order. - Fixed pinconfig node names - Moved pinctrl-* properties after interrupts-* - Switched to interrupts-extended for external components - Marked ADSP as explicitly disabled, with a comment explaining that it stalls the system - Renamed "touchpad" to "trackpad" - Dropped bogus "no-laneswap" property from it6505 node - Moved "realtek,jd-src" property to after all the regulator supplies - Switched to macros for MT6366 regulator "regulator-allowed-modes" - Renamed "vgpu" regulator name to allow coupling, with a comment containing the name used in the design - Renamed "cr50" node name to "tpm" - Moved trackpad_pins reference up to i2c2; workaround for second source component resource sharing. - Fix copyright year - Fixed touchscreen supply name - Mark missing components as disabled instead of deleting the node - Dropped reset-gpios from touchscreen nodes - Drop status = "okay", which is the default This series adds device trees for the various MT8186 Chromebooks that were initially released. These are the Tentacruel / Tentacool devices released by ASUS, and the Steelix / Rusty / Magneton devices released by Lenovo. The device trees are taken from the downstream ChromeOS v5.15 kernel, ported to mainline and cleaned up. Corsola is the Google codename given to the MT8186 platform. This platform has two reference designs, Krabby and Kingler. Kingler was not used in any actual product, and is therefor not included. Steelix is an alternative design put forward and is effectively a mix-and-match of the two reference designs. Most of the core design is shared between the variants. The differences are on which external components, such as the display bridges, are used. Patch 1 cleans up the current list of MediaTek boards. The entries are reordered by SoC model first, then by board name. Patch 2 through 5 add DT binding entries for the Tentacruel/Tentacool, Steelix, Rusty, and Magneton Chromebooks. Patch 6 through 9 add board device tree files for these devices. Patch 6 also adds the corsola dtsi file for the commonalities between the designs, as well as a dtsi file for the krabby reference design. Currently external display support is missing. Audio is not working, as enabling the audio DSP causes my test systems to hang. Please have a look and test if possible.
