[PATCH v3 0/2] ARM: dts: samsung: Add support for Hardkernel ODROID-U2

[Josef Schlehofer]

This series adds the Hardkernel ODROID-U2, the predecessor of the
ODROID-U3, based on the Samsung Exynos4412 Prime SoC.

As with other closely related boards, such as the ODROID-X2 and the
ODROID-X, the ODROID-U2 device tree includes the ODROID-U3 one and
describes only the differences: the micro-USB port is peripheral only,
as there is no VBUS supply switch, there is no expansion header with
SPI, and the 3.5 mm jack is headphone only, with an on-board digital
microphone instead.

Ethernet, microSD, USB peripheral mode, the LED, the fan cooling
device, headphone playback and recording from the digital microphone
were tested on an ODROID-U2 with v1 on Linux 6.12. With v2, everything
except audio was checked again on Linux 6.18; the DTB is the same as in
v1, except for the cs-gpios property of the disabled spi_1 node. The
eMMC was not tested, as no eMMC module was available. The DTB of v3 is
identical to v2.

Changes in v3:
- Fix the line wrapping of samsung,audio-widgets (Henrik)
- Add Reviewed-by from Henrik to the dts patch
- Link to v2: https://lore.kernel.org/all/20261022055208.17746-1-pepe.schlehofer@gmail.com/

Changes in v2:
- Include the ODROID-U3 device tree instead of duplicating it, which
  also resolves the style issues reported by Henrik
- Add Reviewed-by from Henrik to the dt-bindings patch
- Link to v1: https://lore.kernel.org/all/20261018124459.3026-1-pepe.schlehofer@gmail.com/
