This commit adds DTS support for BK4 device from Liebherr. It
uses vf610 SoC from NXP.
Signed-off-by: Lukasz Majewski <lukma@xxxxxxx>
---
Changes for v2:
- Rename enet_ext and audio_ext oscillator names
- Move regulators from simple-bus (and rename to reg_3p3v: regulator-3p3v)
- Add stdout-path property to chosen node
- Move iomuxc node to the end (as it is so large)
- Sort with alphabetical order
- Rename the default pinctrl to "hog"
- Move LED pins definition from "hog" to "led" group
- Add more descriptive names to default pins pinmux definition
- Use spi-slave property to describe node working in this mode
- Rename the spidev3 node to slave
- Introduce new compatible name (lwn,bk4) for spidev driver (to avoid
confusion)
- Update some compatibles to match current kernel
