[PATCH V2 00/11] soc: bcm2835-power: Prepare BCM2711 V3D support

[Peter Robinson]

Hi Stefan,

So I've done some basic boot testing on a rpi4b, rpi4b 8gb, rpi400,
rpi3b+ and rpi zero2w but all headless/remote, overall it looks good.
I'm back home tomorrow when I can test the rpi4 series with the GPU
patches on top with full desktop/display but overall this looks fab!

Peter

> (excluding V3D GPU driver changes) so this can be reviewed and applied faster.

> Changes in V2:
> - add Peter's Reviewed-by
> - simplify schema for rpivid_asb as suggested by Rob
> - fix reference and clarify fallback & error handling in patch #7
> - drop unnecessary newline in patch #9
> - improve log messages as noticed by Peter

> Changes since the mention series:
> - fix DT schema errors
> - make rpivid_asb register optional in DT schema
> - avoid code duplication in BCM2835 ASB enable/disable
> - rework ASB V3D handling so we don't need the V3D flag
> - avoid log errors for optional register
> - use a define for expected ASB_AXI_BRDG_ID result
> - fix copy & paste issues in bcm2835-pm changes
