The only supported cases of otherwise deprecated for FDT "device_type"
property are memory, cpu, and pci. "dma" is not valid, so drop it.

arm64: dts: apm: Add "reg" to "syscon-reboot" and "syscon-poweroff"2025-12-22T10:05:31+00:00Rob Herring (Arm)robh@kernel.org2025-12-16T20:27:50+00:00urn:sha1:a1176f7c5b990244e9a0ee2bdd93c9a36e5fe666
As the nodes already have a unit-address, add the corresponding "reg"
entry which is preferred over "offset".

Use the recommended node name of 'i2c' for the 'i2cslimpro' nodes.

arm64: dts: apm/shadowcat: More clock clean-ups2025-12-22T10:05:30+00:00Rob Herring (Arm)robh@kernel.org2025-12-16T20:27:48+00:00urn:sha1:21bd5fb461eb485768cef99e0ff531a6b84b67d8
A fixed-factor-clock only provides 1 clock, so "#clock-cells" must be 0.
The "snps,designware-i2c" node is not a clock provider, so drop
"#clock-cells.

arm64: dts: apm-shadowcat: Drop "apm,xgene2-pcie" compatible2025-09-23T20:39:18+00:00Rob Herring (Arm)robh@kernel.org2025-09-19T16:15:28+00:00urn:sha1:345518c00ba6bc90c8c557157bc0a6e081e7b2a4
The "apm,xgene2-pcie" compatible is unused, undocumented, and in the
wrong position in the compatible list. Given this is a mature and little
used platform, just remove the compatible rather than fix the order and
document it.

The slimpro nodes are not MMIO devices, so they don't belong under a
"simple-bus" node. Move them to the top level.

arm64: dts: apm: Clean-up clock bindings2025-09-15T13:17:53+00:00Rob Herring (Arm)robh@kernel.org2025-09-10T22:30:19+00:00urn:sha1:668cf076552dd820914484e10cc48600dafd7e71
Clean-up a couple of clock binding related issues in the the X-Gene DTS.
CPU and I2C nodes aren't clock providers and shouldn't have
"#clock-cells" properties.
A fixed-clock only provides 1 clock, so "#clock-cells" must be 0. The
preferred node name is "clock-<freq>" as well.
The "type" property is undocumented and unused, so drop it.

Add missing address-cells 0 to GIC interrupt node to silence W=1
warning:
apm-storm.dtsi:636.4-639.42: Warning (interrupt_map): /soc/pcie@1f2b0000:interrupt-map:
Missing property '#address-cells' in node /interrupt-controller@78010000, using 0 as fallback
Value '0' is correct because:
1. GIC interrupt controller does not have children,
2. interrupt-map property (in PCI node) consists of five components and
the fourth component "parent unit address", which size is defined by
'#address-cells' of the node pointed to by the interrupt-parent
component, is not used (=0)

Remove "bus_num" property which is both unused in the kernel and
undocumented. Most likely they are leftovers from downstream.
