[PATCH 0/3] Some minor RPi5 bits

[Peter Robinson]

These are taken from the downstream kernel device tree. They
are small components that already have upstream support, from
older generation RPis or existing arm IP with just minor
changes for upstream, tested on rev C and D variants.

[PATCH 1/3] arm64: dts: broadcom: bcm2712: add arm PMU

[Peter Robinson]

The bcm2712 SoC in the Raspberry Pi 5 has a standard
arm performance management unit that aligns with the
Cortex-A76 cores that are in the SoC so add the details
in so it can be used.

[PATCH 2/3] arm64: dts: broadcom: bcm2712: Add thermal monitor

[Peter Robinson]

The thermal sensors on the bcm2712 (rpi5) are the same
infrastructure as on the bcm2711 (rpi4) so add those
details so we can get thermal monitoring on the device
as it can get quite hot.

[PATCH 3/3] arm64: dts: broadcom: bcm2712: Add USB OTG port

[Peter Robinson]

The Raspberry Pi 5 has a USB2 OTG port wired up to the
Type-C that uses the same IP in earlier generations so
wire this up so it can be used.
