From 856216b70a41ff3f8c866b627546afa01567b389 Mon Sep 17 00:00:00 2001 From: Matt Ranostay Date: Fri, 17 Jun 2022 08:13:04 -0700 Subject: arm64: dts: ti: k3-j721s2: Fix overlapping GICD memory region GICD region was overlapping with GICR causing the latter to not map successfully, and in turn the gic-v3 driver would fail to initialize. This issue was hidden till commit 2b2cd74a06c3 ("irqchip/gic-v3: Claim iomem resources") replaced of_iomap() calls with of_io_request_and_map() that internally called request_mem_region(). Respective console output before this patchset: [ 0.000000] GICv3: /bus@100000/interrupt-controller@1800000: couldn't map region 0 Fixes: b8545f9d3a54 ("arm64: dts: ti: Add initial support for J721S2 SoC") Cc: linux-stable@vger.kernel.org Cc: Marc Zyngier Cc: Robin Murphy Cc: Nishanth Menon Signed-off-by: Matt Ranostay Acked-by: Marc Zyngier Signed-off-by: Nishanth Menon Link: https://lore.kernel.org/r/20220617151304.446607-1-mranostay@ti.com --- arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/arm64/boot') diff --git a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi index be7f39299894..19966f72c5b3 100644 --- a/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi +++ b/arch/arm64/boot/dts/ti/k3-j721s2-main.dtsi @@ -33,7 +33,7 @@ ranges; #interrupt-cells = <3>; interrupt-controller; - reg = <0x00 0x01800000 0x00 0x200000>, /* GICD */ + reg = <0x00 0x01800000 0x00 0x100000>, /* GICD */ <0x00 0x01900000 0x00 0x100000>, /* GICR */ <0x00 0x6f000000 0x00 0x2000>, /* GICC */ <0x00 0x6f010000 0x00 0x1000>, /* GICH */ -- cgit v1.2.3-59-g8ed1b
