From: Lokesh Vutla Date: Thu, 6 Aug 2020 07:48:20 +0000 (+0530) Subject: dt-bindings: irqchip: ti, sci-inta: Update docs to support different parent. X-Git-Tag: v5.9-rc3~3^2^2~10 X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=6dde29dc31aa265a79d9e6b3571987cfa4b179cc;p=thirdparty%2Fkernel%2Flinux.git dt-bindings: irqchip: ti, sci-inta: Update docs to support different parent. Drop the firmware related interrupt ranges and use the hardware specified interrupt numbers within Interrupt Aggregator. This ensures interrupt aggregator DT node need not assume any interrupt parent type.
