Hi Simon, Magnus,
This patch series adds the second Cortex-A57 CPU core, and the
Cortex-A53 L2 cache-controller and CPU 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.
Tested on r8a7796/salvator-x, with CPU hot(un)plug and system suspend.
Thanks for applying!
