This patch series completes the description of the Cortex-A76 clusters by describing L3 caches, CPU cores 1-3, CPU map, PSCI for CPU bring up, CPUIdle, CPU core clocks, and CPU core operating points. This has been tested on the White-Hawk development board, where now all 4 Cortex-A76 CPU cores are available after boot. All but the first CPU core can be controlled from sysfs (/sys/*/*/cpu/cpu[0-3]/online). CPU core performance follows the CPU core clocks, when changing the frequency of the latter. I plan to queue this in renesas-devel for v6.2. Thanks for your comments!
