Do you want to keep them for internal use, as I suppose only rev6 is available to the general public, correct? I'm fine with keeping the old revisions if that's of use for you, otherwise I'd prefer to delete them.

Hi Hsin-Yi, Apart from the maintainer comments, a few more comments ... cc'ing Matthias and Doug who I know played a bit with the pwm-backlight for the uprev of the veyron devices, and you might be interested in his feedback in general.

Note that this imply a userspace change but /sys/class/backlight/backlight is more aligned with other boards (I guess) when you have only one backlight. See for example: git grep backlight arch/arm64/boot/* > + compatible = "pwm-backlight"; > + pwms = <&pwm0 0 1000000>; > + brightness-levels = < > + 0 16 32 48 64 80 96 112 > + 128 144 160 176 192 208 224 240 > + 255 > + >; > + default-brightness-level = <9>; The reason you see the display too dark is because userspace sets and remembers the default value you have using the above configuration which is only 16 levels. So after removing the two above properties you should set a new brightness from userspace. AFAIK 16 levels is not enough to have fancy backlight effects on Chrome OS userspace, at least is not enough for Rockchip devices so I suppose is the same for Mediatek. You have to options here. A) Remove brightness-levels and default-brightness-level. This will end with a non-linear brightness curve for the backlight up to 4095 levels. # cat max_brightness 4095 B) Use the num-interpolated-steps and default-brightness-level properties. This will end with a linear curve brightness. Similar to what is done for veyron devices but in this case with more levels because the PWM to control the backlight is 16-bits instead of 8-bits for veyron devices. * https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/arch/arm/boot/dts/rk3288-veyron-edp.dtsi#n42 My guess is that you're interested on option B here to be coherent with other Chromebooks. > + power-supply = <&bl_fixed_reg>; > + enable-gpios = <&pio 95 GPIO_ACTIVE_HIGH>; > + > + pinctrl-names = "default"; > + pinctrl-0 = <&disp_pwm0_pins>; > + status = "okay"; > + }; > + > + bl_fixed_reg: fixedregulator@2 { > + compatible = "regulator-fixed"; > + regulator-name = "bl_fixed"; > + regulator-min-microvolt = <1800000>; > + regulator-max-microvolt = <1800000>; > + startup-delay-us = <1000>; > + enable-active-high; > + gpio = <&pio 32 GPIO_ACTIVE_HIGH>; > + pinctrl-names = "default"; > + pinctrl-0 = <&bl_fixed_pins>; > + }; > + > + chosen { > + stdout-path = &uart0; You probably want stdout-path = "serial0:115200n8"; That way you'll get serial without needing to specify the console in the kernel command line.

I still have problems with this, I need to comment this line and add non-removable as a workaround in order to boot from the SD-card. I think that the problem is that is GPIO_ACTIVE_LOW (it works for me, but I don't have the schematics to confirm) > + vmmc-supply = <&mt6397_vmch_reg>; > + vqmmc-supply = <&mt6397_vmc_reg>; > +}; > + > +&mmc3 { > + status = "okay";

You could evaluate either way. One of the reasons to chose the interpolated-steps for veyron was that some veyron panels require a minimum backlight level to work properly. This can be easily configured with the linear curve, but currently not with the non-linear one. Another reason was to keep the backlight curve of a released device unaltered, though I think that's not strictly required as long as the behavior with the non-linear curve is close/good enough. Chrome OS user space supports both types of curves, for a new device I would probably start with a non-linear curve, and only change that if the resulting behavior doesn't meet expectations for some reason.

Elm is Acer Chromebook R13. Hana is Lenovo Chromebook. Both uses mt8173 SoC. Signed-off-by: Hsin-Yi Wang <hsinyi@chromium.org> --- Changes in v2: - remove downstream nodes and unused nodes - use GPIO_ACTIVE_LOW for ps8640 gpios - move trackpad to hana --- arch/arm64/boot/dts/mediatek/Makefile | 3 + .../dts/mediatek/mt8173-elm-hana-rev7.dts | 27 + .../boot/dts/mediatek/mt8173-elm-hana.dts | 16 + .../boot/dts/mediatek/mt8173-elm-hana.dtsi | 60 + arch/arm64/boot/dts/mediatek/mt8173-elm.dts | 15 + arch/arm64/boot/dts/mediatek/mt8173-elm.dtsi | 1040 +++++++++++++++++ 6 files changed, 1161 insertions(+) create mode 100644 arch/arm64/boot/dts/mediatek/mt8173-elm-hana-rev7.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8173-elm-hana.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8173-elm-hana.dtsi create mode 100644 arch/arm64/boot/dts/mediatek/mt8173-elm.dts create mode 100644 arch/arm64/boot/dts/mediatek/mt8173-elm.dtsi
