Wed May 9 08:23:22 PDT 2018
Add a device node for the second Cortex-A53 CPU core on the Renesas
R-Car V3M (r8a77970) SoC, and adjust the interrupt delivery masks for
ARM Generic Interrupt Controller and Architectured Timer.
Signed-off-by: Geert Uytterhoeven <geert+renesas at glider.be>
---
v2:
- Adjust GIC_CPU_MASK_SIMPLE(),
- Use symbolic core clock and power domain indices.
