- Subject: [PATCH] cpufreq: armada-8k: add ap807 support
- Add support for the Armada AP807 die to armada-8k. This uses a
- different compatible for the CPU clock which needs to be added to
- the cpufreq driver.
- This commit takes a different approach to the WindRiver patch
- "cpufreq: armada: enable ap807-cpu-clk" in that rather than calling
- of_find_compatible_node() for each compatible, we use a table of
- IDs instead.
