Those regulators are for the Atmel 1664S touchscreen which has a public data sheet. My best guess would be that those are VDD, AVDD and XVDD but I have no idea how to match them or whether this is actually an accurate observation.

It seems the bootloader is setting this up. The regulator naming suggests, that it would be LDO23. What should I do here? Currently no driver is using it but it's needed for the backlight dimming which I currently still have some trouble with. > > +}; (...) > > + > > +&i2c_7 { > > + samsung,i2c-sda-delay = <100>; > > + samsung,i2c-slave-addr = <0x10>; > > + samsung,i2c-max-bus-freq = <400000>; > > + pinctrl-0 = <&i2c7_bus>; > > + pinctrl-names = "default"; > > + status = "okay"; > > + > > + max77686: max77686_pmic@9 { > > + compatible = "maxim,max77686"; > > + interrupt-parent = <&gpx0>; > > + interrupts = <7 IRQ_TYPE_NONE>; > > + pinctrl-0 = <&max77686_irq>; > > + pinctrl-names = "default"; > > + reg = <0x09>; > > + #clock-cells = <1>; > > + > > + voltage-regulators { > > Just "regulators" and no empty line after this. > > You should define all regulators here.

What I don't know is their name and what they are used for. Interestingly apart from two LDOs, the voltages did match exactly with those from the midas DT, so it could be very similar. The two non-matching were only off by 0.1V.

It seems the bootloader is setting this up. The regulator > naming suggests, that it would be LDO23.

The LDO23 is most likely for the touch panel ADC, not for the SoC one. Here it could be LDO3. You have to put something otherwise dtschema will complain. Go with the LDO3 and maybe a comment like: "TBD, not confirmed". > > > > +}; > > (...) > > > > + > > > +&i2c_7 { > > > + samsung,i2c-sda-delay = <100>; > > > + samsung,i2c-slave-addr = <0x10>; > > > + samsung,i2c-max-bus-freq = <400000>; > > > + pinctrl-0 = <&i2c7_bus>; > > > + pinctrl-names = "default"; > > > + status = "okay"; > > > + > > > + max77686: max77686_pmic@9 { > > > + compatible = "maxim,max77686"; > > > + interrupt-parent = <&gpx0>; > > > + interrupts = <7 IRQ_TYPE_NONE>; > > > + pinctrl-0 = <&max77686_irq>; > > > + pinctrl-names = "default"; > > > + reg = <0x09>; > > > + #clock-cells = <1>; > > > + > > > + voltage-regulators { > > > > Just "regulators" and no empty line after this. > > > > You should define all regulators here.

Just add the entries with generic names, like: arch/arm/boot/dts/exynos5410-odroidxu.dts I would not put here min-max constraints from bootloader because pretty often it has only an initial setup for specific frequency - just to make it booting. If you have the constraints (min-max, always on) from vendor sources, you could add them. Best regards, Krzysztof

What I noticed when all the LDOs are defined, the device reboot behaviour is different. Instead of the usual 1-2 seconds for screen off and on again, it's now more like 10 seconds. Cheers Martin
