| Subject: [PATCH 068/286] ARM: dts: r8a7792: Add INTC-SYS clock to device tree |
| |
| Link the ARM GIC to the INTC-SYS module clock, and add it to the "always |
| on" PM Domain, so it can be power managed using that clock. |
| |
| Note that currently the GIC-400 driver doesn't support module clocks nor |
| Runtime PM, so this must be handled as a critical clock. |
