Subject: [PATCH v2 07/18] ARM: dts: qcom: reduce pci IO size to 64K for ipq8064
Date: Fri, 18 Feb 2022 01:29:45 +0100 [thread overview]
Message-ID: <20220218002956.6590-8-ansuelsmth@gmail.com> (raw)
In-Reply-To: <20220218002956.6590-1-ansuelsmth@gmail.com>
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.
