Hi all, this series targets to enable cpufreq for Zynq which needs some preparation in the DT and clocksource driver to work. The first two patches are cleaning up the DT. The first just removes an invalid property and the second adds a 'cpus' node to the DT. Those changes should be okay independently of the final cpufreq patch. Then the cadence_ttc patches: The first one fixes an issue which - I think - shows in combination with cpuidle. I saw a kernel WARN triggered because the driver calls clk_get_rate() from interrupt context. 3/7 should fix that. Patches 4 and 5 then are the actual preparation for cpufreq. And 6 is an optimization to use the timer HW a little bit more efficient. And the final patch adds the required DT properties, platform devices etc. to use cpufreq-cpu0 to scale the CPU frequency.
