515ffb40cb bmips: dts: fix pinctrl error
Some checks failed
Build Kernel / Build all affected Kernels (push) Has been cancelled
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.

967520800a bmips: bcm6362/bcm63268: enable HW RNG
This enables the HW Random Number Generator on the BCM6362 and BCM63268 SoCs,
which is the same one used on BCM6368 SoC.

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.

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.
