From 84909e85881d67244240c9f40974ce12a51e3886 Mon Sep 17 00:00:00 2001 From: Ansuel Smith Date: Tue, 11 May 2021 23:09:45 +0200 Subject: [PATCH] ARM: dts: qcom: reduce pci IO size to 64K The current value is probably a typo and is actually uncommon to find 1MB IO space even on a x86 arch. Also with recent changes to the pci driver, pci1 and pci2 now fails to function as any connected device fails any reg read/write. Reduce this to 64K as it should be more than enough and 3 * 64K of total IO space doesn't exceed the IO_SPACE_LIMIT hardcoded for the ARM arch.
