From 8fafb7e5c041814876266259e5e439f93571dcef Mon Sep 17 00:00:00 2001 From: Christian Marangi Date: Thu, 7 Jul 2022 03:09:40 +0200 Subject: [PATCH 6/8] ARM: dts: qcom: ipq8064: reduce pci IO size to 64K The current value for pci IO is problematic for ath10k wifi card commonly connected to ipq8064 SoC. 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.
