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?

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.
