irqchip: RISC-V per-HART local interrupt controller driver
The RISC-V per-HART local interrupt controller manages software interrupts, timer interrupts, external interrupts (which are routed via the platform level interrupt controller) and other per-HART local interrupts. We add a driver for the RISC-V local interrupt controller, which eventually replaces the RISC-V architecture code, allowing for a better split between arch code and drivers. The driver is compliant with RISC-V Hart-Level Interrupt Controller DT bindings located at: Documentation/devicetree/bindings/interrupt-controller/riscv,cpu-intc.txt Co-developed-by: Palmer Dabbelt <palmer@dabbelt.com> Signed-off-by: Anup Patel <anup.patel@wdc.com> [Palmer: Cleaned up warnings] Signed-off-by: Palmer Dabbelt <palmer@dabbelt.com>
