Subject: [PATCH 0/3] Add AMBA bus probing support to ACPI
Date: Wed, 30 Sep 2015 11:38:47 +0100 [thread overview]
Message-ID: <1443609530-21524-1-git-send-email-graeme.gregory@linaro.org> (raw)
As discussed when Shannon Zhao sent a patch to add platform_device support
to pl061 driver. Russel and other maintainers prefered that ACPI learned
how to create AMBA devices rather than converting/adding platform_device
support to AMBA drivers.
http://comments.gmane.org/gmane.linux.ports.arm.kernel/431364
1) Adds basic AMBA device probing support to ACPI, it uses a whitelist of
device IDs as the number of AMBA devices is limited. Currently the two ids
present are those used in QEMU for arm64.
2) Adds the plumbing into ACPI probe sequence.
3) From ACPI pl011 is only defined (SBSA document) to be in SBSA mode which has
reduced functionality. There may be a better method to do this that I have
overlooked.
Thanks
Graeme
