You are right, node names should have underscores, but in the end I was following the bindings (Documentation/devicetree/bindings/input/touchscreen/ stmpe.txt) naming 'stmpe_touchscreen' and 'stmpe_adc' in the example. Each subdevice has it's own compatible, so there should be no issue. Using just 'gpio' and 'touchscreen' below I didn't notice any difference. > > + compatible = "st,stmpe-gpio"; > > + gpio-controller; > > + #gpio-cells = <2>; > > + /* GPIO 5-7 used for touch */ > > + st,norequest-mask = <0xf0>; > > + gpio-line-names = "GPIO_ADC_I2C1_1", > > + "GPIO_ADC_I2C1_2", > > + "GPIO_ADC_I2C1_3", > > + "GPIO_ADC_I2C1_4"; > > + }; > > + > > + stmpe_touchscreen { > > Same problems.

This is neither GPIO > nor PWM. You are right, no underscores. Well, actually it's used as a GPIO for backlight brightness, on a signal called 'PWM_0'. But I'll go for 'led-0' and 'led-1' for node names and remove the labels, as they are type GPIO. > > + label = "pca9530:pwm0"; > > + type = <PCA9532_TYPE_GPIO>; > > + }; > > + > > + gpio_pwm_1 { > > + label = "pca9530:pwm1"; > > + type = <PCA9532_TYPE_GPIO>; > > + }; > > + }; > > + > > +}; > > + > > +&i2c1 { > > + status = "okay"; > > +}; > > + > > +&lpuart0 { > > + status = "okay"; > > + linux,rs485-enabled-at-boot-time; > > +}; > > + > > +&mdio0 { > > + sgmii_phy03: ethernet-phy@3 { > > + compatible = "ethernet-phy-ieee802.3-c22"; > > + reg = <0x03>; > > + ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>; > > + ti,clk-output-sel = <DP83867_CLK_O_SEL_OFF>; > > + ti,dp83867-rxctrl-strap-quirk; > > + }; > > + > > + rgmii_phy04: ethernet-phy@4 { > > + compatible = "ethernet-phy-ieee802.3-c22"; > > + reg = <0x04>; > > + ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_50_NS>; > > + ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>; > > + ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>; > > + ti,clk-output-sel = <DP83867_CLK_O_SEL_OFF>; > > + }; > > + > > + rgmii_phy0c: ethernet-phy@c { > > + compatible = "ethernet-phy-ieee802.3-c22"; > > + reg = <0x0c>; > > + ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_50_NS>; > > + ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_00_NS>; > > + ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>; > > + ti,clk-output-sel = <DP83867_CLK_O_SEL_OFF>; > > + }; > > +}; > > + > > +&pwm6 { > > + status = "okay"; > > +}; > > + > > +&pwm7 { > > + status = "okay"; > > +}; > > + > > +&sai1 { > > + status = "okay"; > > +}; > > + > > +&sata { > > + /delete-property/ dma-coherent; > > + status = "okay"; > > +}; > > + > > +&uart0 { > > + status = "okay"; > > +}; > > + > > +&uart1 { > > + status = "okay"; > > +}; > > + > > +&usb3 { > > + /* > > + * Although DR connector, VBUS is always driven, so > > + * restrict to host mode. > > + */ > > + dr_mode = "host"; > > + status = "okay"; > > +}; > > diff --git a/arch/arm/boot/dts/ls1021a-tqmls1021a.dtsi > > b/arch/arm/boot/dts/ls1021a-tqmls1021a.dtsi new file mode 100644 > > index 0000000000000..1ab518c489252 > > --- /dev/null > > +++ b/arch/arm/boot/dts/ls1021a-tqmls1021a.dtsi > > @@ -0,0 +1,93 @@ > > +// SPDX-License-Identifier: (GPL-2.0-or-later OR X11) > > +/* > > + * Copyright 2013-2014 Freescale Semiconductor, Inc. > > + * Copyright 2018-2023 TQ-Systems GmbH <linux@ew.tq-group.com>, > > + * D-82229 Seefeld, Germany. > > + * Author: Alexander Stein > > + */ > > + > > +#include "ls1021a.dtsi" > > + > > +/ { > > + model = "TQMLS102xA SOM"; > > + compatible = "tq,ls1021a-tqmls1021a", "fsl,ls1021a"; > > + > > + reg_3p3v_som: regulator-3p3v-som { > > + compatible = "regulator-fixed"; > > + regulator-name = "3P3V_SOM"; > > + regulator-min-microvolt = <3300000>; > > + regulator-max-microvolt = <3300000>; > > + regulator-always-on; > > + }; > > +}; > > + > > +&esdhc { > > + compatible = "fsl,esdhc", "fsl,ls1021a-esdhc"; > > + /* e-MMC over 8 data lines */ > > + bus-width = <8>; > > + status = "okay"; > > +}; > > + > > +&i2c0 { > > + status = "okay"; > > + > > + mc34vr500: pmic@8 { > > + reg = <0x08>; > > No compatible? What's this? That's a DC/DC regulator on the module, currently without any driver support. It's controlled by the PMC, see below. We had an internal discussion as well whether to state clients without a driver (and thus no compatible) on the i2c bus. What is the guidelines for DT?

That's a PMC monitoring voltages using the DC/DC regulator from above.
