Subject: [PATCH 2/2] bmips: add device tree example for BCM6358
This adds a device tree example for SFR Neufbox4 (Sercomm version), which
also serves as a real example for brcm,bcm6358-leds.
Signed-off-by: Álvaro Fernández Rojas <noltari@...il.com>
---
v5: more device tree improvements
- There is just ohci/ehci node.
- Avoid using underscores in node names.
- Use interrupt-controller for cpu_intc.
- Rename uart aliases to serial.
v4: Device tree improvements:
- Switch to native-endian for syscon.
- Switch to bcm6345-l1-intc interrupt controller.
- Add ehci and ohci nodes.
v3: Device tree fixes
- Use interrupt-controller instead of periph_intc.
- Use led@# instead of naming the LEDs.
v2: Remove led0 alias and use stdout-path only
