[Qemu-devel] [PATCH 26/28] riscv: hw: Update PLIC device tree


From: Bin Meng
Subject: [Qemu-devel] [PATCH 26/28] riscv: hw: Update PLIC device tree
Date: Mon, 5 Aug 2019 09:00:21 -0700

This removes "reg-names" and "riscv,max-priority" properties of the
PLIC node from device tree, and updates its compatible string, to
keep in sync with the Linux kernel device tree.
