Newsgroups	dev.linux.lists.spacemit,org.infradead.lists.linux-riscv,org.kernel.vger.linux-devicetree,org.kernel.vger.linux-kernel
Message-ID	<[email protected]>

Add support for the ACLINT MSWI found in the SpacemiT K3 SoC. The
hardware provides a ACLINT MSWI unit. Adding riscv,aclint-mswi as a
fallback compatible allows direct reuse of existing OpenSBI driver.
