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.
