d1e9c50d06 bmips: dts: fix pinctrl error
Some checks are pending
Build Kernel / Build all affected Kernels (push) Waiting to run
The kernel logs the error "bcm6368_nand 10000200.nand: there is not valid
maps for state default" on boot and all nand pins show as UNCLAIMED in
sysfs pinmux-pins.

bcm6362.dtsi, bcm6368.dtsi and bcm63268.dtsi use the undocumented property
group which the driver doesn't understand. This has been documented upstream
in commit caf963efd4b0b9ff42ca12e52b8efe277264d35b.

Replacing group with pins allows the nand pins to be properly configured.

04c5c1ff70 bmips: fix kernel panic caused by missing CBR address
The cbr-reg DTS property uses a wrong name causing the RAC kernel
panic again on BCM6358 BCM6368 boards.

Use the correct cbr-reg name property.

6bbb75dfdc bmips: dts: move leds dt-bindings include to SoCs
bmips has all the dt-bindings includes inside each SoC .dtsi files, so let's
move the new includes there instead of adding them to each board .dts files.

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.
