Thanks for the link :) would be nice to have this script to be part of the kernel. The script follows the rules in [1] I'm just used to have common properties like pinctrl-* in front of the device specific properties e.g. "enable-active-high". But this rule is not part of [1] so I can't blame the script.

I don't see any reason why the kernel shouldn't have such a script, it makes the life easier for all of us (incl. the dt-maintainers).

The IOTA2 Lumpy board is based on the i.MX8MPlus EVK. Basic features are: - 4GB LPDDR4 - 64GB eMMC - 2x 1GB Ethernet - USB 3.0 Type-C dual role port, without power delivery - USB 3.0 Type-A host port - RGB LED - PWM driven - speaker - PWM driven - RTC with super capacitor backup Signed-off-by: Michal Vokáč <michal.vokac@ysoft.com> --- v4: - Moved the iomuxc node to the end of the file. - Moved the bus-width and non-removeable properties below the pinctrl-* properties in &usdhc3 node. - Moved the fsl,ext-reset-output below the pinctrl-* properties in &wdog1 node. v3: - Dropped pinctrl-names property from &usb_dwc3_1 node. v2: - Dropped unused property from pwm4 node. - Sorted all nodes and properties using dt-format tool from Frank. arch/arm64/boot/dts/freescale/Makefile | 1 + .../boot/dts/freescale/imx8mp-iota2-lumpy.dts | 423 ++++++++++++++++++ 2 files changed, 424 insertions(+) create mode 100644 arch/arm64/boot/dts/freescale/imx8mp-iota2-lumpy.dts
