2025-02-21mips: dts: realtek: Fold rtl83xx into rtl838xSander Vanheule
rtl83xx.dtsi was once (presumably) created as a base for both RTL838x and RTL839x SoCs. Both SoCs have a different CPU and the peripherals require different compatibles. Fold rtl83xx.dtsi into rtl838x.dtsi, currently only supporting RTL838x SoCs, and create the RTL839x base include later when required.

2025-02-21mips: dts: realtek: Add address to SoC node nameSander Vanheule
Although not strictly required by the simple-bus binding, add the bus offset to the node name to be consistent with other nodes. Also drop the node label as it is not referenced anywhere.

2025-02-21mips: dts: realtek: Clean up CPU clocksSander Vanheule
The referenced CPU clock does not require any additional #clock-cells, so drop the extraneous '0' in the referenced CPU clock. The binding for MIPS cpus also does not allow for the clock-names property, so just drop it. This resolves some error message from 'dtbs_check': cpu@0: clocks: [[4], [0]] is too long 'clock-names' does not match any of the regexes: 'pinctrl-[0-9]+' Signed-off-by: Sander Vanheule <sander@svanheule.net> Reviewed-by: Chris Packham <chris.packham@alliedtelesis.co.nz> Tested-by: Chris Packham <chris.packham@alliedtelesis.co.nz> # For RTL9302C Signed-off-by: Thomas Bogendoerfer <tsbogend@alpha.franken.de>
