Hi Simon, Magnus,
This patch series adds the second Cortex-A57 CPU core, the Cortex-A57
PMU, and the Cortex-A53 L2 cache-controller, CPU, and PMU nodes on the
Renesas R-Car M3-W SoC to its DTS file.
Note that these patches add hardware description; actual enabling of the
CPU depends on the PSCI firmware.
With the current firmware version (v2.16.0), only the CA57 CPU cores are
enabled, hence the last patch does not introduce undeterministic
scheduling behavior due to migration between big and LITTLE cores.
Changes compared to v1:
- Add Cortex-A57 and Cortex-A53 PMU nodes,
- Drop unit address and reg property for integrated cache-controller.
Tested on r8a7796/salvator-x, with CPU hot(un)plug and system suspend.
Thanks for applying!
