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 <maz@kernel.org> Cc: Robin Murphy <robin.murphy@arm.com> Cc: Nishanth Menon <nm@ti.com> Signed-off-by: Matt Ranostay <mranostay@ti.com> Acked-by: Marc Zyngier <maz@kernel.org> Signed-off-by: Nishanth Menon <nm@ti.com> Link: https://lore.kernel.org/r/20220617151304.446607-1-mranostay@ti.com
