Hi Graeme,
I have't seen any. Can you please forward me if you have got in your inbox.

Hi Naresh,
Isn't the ASL in the first post of the series?

Hi Anderson,
The patches applied, compiled (except there was a conflict in the last patch "Hack clock names to get prototype running"). Can you please post the ASL code changes patch ? looks like ASL changes are different from what we have written originally.

This is a proposal for ACPI driver probing of the ARM AMBA devices currently listed under ‘iofpga’ in the RTSM dts file. The main addition is drivers/amba/acpi.c which fits the role of an AMBA bus ‘connector resource’ for ACPI using struct amba_device.
I have not yet figured out the implementation details regarding clocks (handled in the dts file with clock-names). However, I have included a proposed ASL format for clock information in the DSDT example below. With the last patch that hacks the clock info, this prototype will run on the Foundation and RTSM models.
These patches require Hanjun’s fixed-clock patches to be applied first on top of a Linaro ACPI kernel: https://git.linaro.org/gitweb?p=arm/acpi/leg-kernel.git%3Ba=summary
Please comment on both the concept and the implementation.
