This reverts commit fc9dfeb1383287631ad5c5a676a2558b799db6e9. There are still some stability problems on some SI boards so bring this back.

drm/radeon/dpm: fetch the max clk from voltage dep tables helper

2013-09-23T14:29:51Z

This patch adds a helper function to fetch the max clock from the voltage clock dependecy tables. Clocks above that level tend to be unstable and will require additional driver tweaks in order to work properly. This patch implemented the helper function to fetch the max clocks from the dependency tables. The following patches implement the per-asic clock filtering.

drm/radeon/kms: add dpm support for cayman (v5)

2013-06-27T23:16:10Z

This adds dpm support for cayman asics. This includes: - clockgating - dynamic engine clock scaling - dynamic memory clock scaling - dynamic voltage scaling - dynamic pcie gen1/gen2 switching (requires additional acpi support) - power containment - shader power scaling Set radeon.dpm=1 to enable. v2: fold in tdp fix v3: fix indentation v4: fix 64 bit div v5: attempt to fix state enable Signed-off-by: Alex Deucher Reviewed-by: Jerome Glisse
