Add support for the SpacemiT K3 ACLINT MTIMER, which provides per-hart timer interrupts in Machine mode. Signed-off-by: Junhui Liu <junhui.liu@pigmoral.tech> Acked-by: Conor Dooley <conor.dooley@microchip.com> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
…iT K3 Add support for the SpacemiT K3 ACLINT MSWI, which provides per-hart software interrupts for inter-processor communication in Machine mode.

…iT K3 Add support for the SpacemiT K3 ACLINT SSWI, which provides inter-processor interrupts in Supervisor mode without calling into Machine-mode firmware.

The SpacemiT K3 implements separate ACLINT MSWI, MTIMER and SSWI devices. The existing spacemit,k3-clint compatible incorrectly describes the SSWI register space as a legacy CLINT. Deprecate this compatible in favor of the K3-specific ACLINT compatibles.

Add a match entry for the spacemit,k3-aclint-sswi compatible. The K3 SSWI device requires no special handling and can use the existing generic ACLINT SSWI initialization function. Signed-off-by: Junhui Liu <junhui.liu@pigmoral.tech> Signed-off-by: Linux RISC-V bot <linux.riscv.bot@gmail.com>
The K3 implements separate ACLINT MSWI, MTIMER and SSWI devices. The existing CLINT node at 0xe081c000 incorrectly describes the SSWI register space as a legacy CLINT. Replace the CLINT node with an SSWI interrupt controller using the K3-specific compatible and supervisor software interrupt IDs. Add the MSWI and MTIMER nodes to describe the machine-level devices for firmware such as OpenSBI. Use the secure addresses for MSWI and MTIMER, as their non-secure aliases are inaccessible. Keep SSWI at its non-secure address, 0xe081c000, because an efuse bit can restrict access to its secure alias at 0xf181c000 to Machine mode.
