From 0d4f74792e2946cb2ef40a1673851eda1041358c Mon Sep 17 00:00:00 2001 From: pdeschrijver@nvidia.com Date: Tue, 29 Nov 2011 18:29:19 -0700 Subject: arm/tegra: convert tegra20 to GIC devicetree binding Convert tegra20 IRQ intialization to the GIC devicetree binding. Modify the interrupt definitions in the dts files according to Documentation/devicetree/bindings/arm/gic.txt v3 (swarren): * Moved of_irq_init() call into board-dt.c to avoid ifdef'ing it. - Even with a dummy replacement if !CONFIG_OF, the reference from tegra_dt_irq_match[] to gic_of_init() would still have to be ifdef'd - It's plausible that tegra_dt_irq_match[] may need to contain more entries in the future, and defining what they are seems more suitable for board-dt.c than irq.c v2 (swarren): * Removed some stale GIC init code from board-dt.c * Undid some accidental 0x -> 0x0 search/replace.
