2f8e90739a Revert "bmips: add missing switch cpu label"
This reverts commit dc0de05e10.
As pointed out by @BKPepe and @arinc9 this was removed by 9df035b since it
isn't needed.

9df035b3ea treewide: remove label = "cpu" from DSA dt-binding
This is not used by the DSA dt-binding, so remove it from all devicetrees.

4165e565d2 bmips: switch to upstream ehci overcurrent flag
After backporting upstream ehci overcurrent patches we need to use spurious-oc
instead of ignore-oc.

7f04d67517 bmips: add experimental PCI/PCIe support
These PCI drivers are a bit hacky and definitely not suitable for upstreaming,
but hopefully we can use them as a base for developing proper upstream PCI
drivers.

28dcb74de3 bmips: add experimental ethernet support
This adds experimental ethernet support for BCM6318, BCM6328, BCM6362, BCM6368
and BCM63268.
BCM6358 needs a different driver, so there's no support for now.

Working devices:
- Comtrend AR-5315u
- Comtrend AR-5387un
- Comtrend VR-3025u
- Comtrend VR-3032u

Not working devices:
- Netgear DGND3700 v2 (no idea on how the external switch is connected)
- Huawei HG556a ver B (BCM6358 needs a separate driveer)

029093a302 bmips: add new target
This target has full device tree support, thus reducing the number of
patches needed for bcm63xx, in which there's a patch for every board.

The intention is to start with a minimal amount of downstream patches and
start upstreaming all of them.

Current status:
 - Enabling EHCI/OHCI on BCM6358 causes a kernel panic.
 - BCM63268 lacks Timer Clocks/Reset support.
 - No PCI/PCIe drivers.
 - No ethernet drivers.
