2021-05-25ARM: dts: renesas: Move enable-method to CPU nodesGeert Uytterhoeven1-1/+2
According to Documentation/devicetree/bindings/arm/cpus.yaml, the "enable-method" property should be a property of the individual CPU nodes, and not of the parent "cpus" container node. However, on R-Car Gen2 and RZ/G1 SoCs, the property is tied to the "cpus" node instead. Secondary CPU bringup and CPU hot (un)plug work regardless, as arm_dt_init_cpu_maps() falls back to looking in the "cpus" node. The cpuidle code does not have such a fallback, so it does not detect the enable-method. Note that cpuidle does not support the "renesas,apmu" enable-method yet, so for now this does not make any difference.

2017-10-16ARM: dts: r8a7794: Use R-Car GPIO Gen2 fallback compat stringSimon Horman1-7/+7
Use newly added R-Car GPIO Gen2 fallback compat string in place of now deprecated non-generation specific R-Car GPIO fallback compat string in the DT of the r8a7794 SoC. This should have no run-time effect as the driver matches against the per-SoC compat string before considering the fallback compat string.

2017-09-19ARM: dts: r8a7794: Add reset control propertiesGeert Uytterhoeven1-0/+64
Add properties to describe the reset topology for on-SoC devices: - Add the "#reset-cells" property to the CPG/MSSR device node, - Add resets and reset-names properties to the various device nodes. This allows to reset SoC devices using the Reset Controller API. Note that resets usually match the corresponding module clocks. Exceptions are: - The audio module has resets for the Serial Sound Interfaces only, - The display module has only a single reset for all DU channels, but adding reset properties for the display is postponed.

2017-02-07ARM: DTS: Fix register map for virt-capable GICMarc Zyngier1-1/+1
Since everybody copied my own mistake from the DT binding example, let's address all the offenders in one swift go. Most of them got the CPU interface size wrong (4kB, while it should be 8kB), except for both keystone platforms which got the control interface wrong (4kB instead of 8kB). In a few cases where I knew for sure what implementation was used, I've added the "arm,gic-400" compatible string. I'm 99% sure that this is what everyone is using, but short of having the TRM for all the other SoCs, I've left them alone.
