The patch set will add ACPI probing for v2m_sysreg and allocate a LINA0006 platform ID. Also remove the defination under foundation-v8-acpi.dts file.

This binding has now been moved to DSDT so remove FDT.

Hi Naresh,
This does not look like it uses any form of bus implementation? Is this patch series a stop-gap to allow you to convert the bus architecture?
Also can you make sure that DTS and ASL changes are to both Foundation and RTSM models as LAVA currently only uses RTSM model to test.

Hi Graeme,
Yes, You are right. First it is required to do bus enumeration. Then the devices enumeration which are depend on that bus. I will re-work on it.
Thanks Naresh
