From 76d777ae045e345ccfbf2d7c873674de09a8a041 Mon Sep 17 00:00:00 2001 From: Johan Hovold Date: Thu, 14 Jul 2022 09:13:42 +0200 Subject: [PATCH] dt-bindings: PCI: qcom: Add SC8280XP to binding Add the SC8280XP platform to the binding. SC8280XP use four host interrupts for MSI routing so remove the obsolete comment referring to newer chipsets supporting one or eight interrupts (e.g. for backwards compatibility).
