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. + +Signed-off-by: Ansuel Smith <ansuelsmth@gmail.com> +--- + arch/arm/boot/dts/qcom-ipq8064.dtsi | 6 +++--- + 1 file changed, 3 insertions(+), 3 deletions(-) + +--- a/arch/arm/boot/dts/qcom-ipq8064.dtsi ++++ b/arch/arm/boot/dts/qcom-ipq8064.dtsi +@@ -1085,7 +1085,7 @@ + #address-cells = <3>; + #size-cells = <2>; + +- ranges = <0x81000000 0 0x0fe00000 0x0fe00000 0 0x00100000 /* downstream I/O */ ++ ranges = <0x81000000 0 0x0fe00000 0x0fe00000 0 0x00010000 /* downstream I/O */ + 0x82000000 0 0x08000000 0x08000000 0 0x07e00000>; /* non-prefetchable memory */ + + interrupts = <GIC_SPI 35 IRQ_TYPE_LEVEL_HIGH>; +@@ -1136,7 +1136,7 @@ + #address-cells = <3>; + #size-cells = <2>; + +- ranges = <0x81000000 0 0x31e00000 0x31e00000 0 0x00100000 /* downstream I/O */ ++ ranges = <0x81000000 0 0x31e00000 0x31e00000 0 0x00010000 /* downstream I/O */ + 0x82000000 0 0x2e000000 0x2e000000 0 0x03e00000>; /* non-prefetchable memory */ + + interrupts = <GIC_SPI 57 IRQ_TYPE_LEVEL_HIGH>; +@@ -1187,7 +1187,7 @@ + #address-cells = <3>; + #size-cells = <2>; + +- ranges = <0x81000000 0 0x35e00000 0x35e00000 0 0x00100000 /* downstream I/O */ ++ ranges = <0x81000000 0 0x35e00000 0x35e00000 0 0x00010000 /* downstream I/O */ + 0x82000000 0 0x32000000 0x32000000 0 0x03e00000>; /* non-prefetchable memory */ + + interrupts = <GIC_SPI 71 IRQ_TYPE_LEVEL_HIGH>; |
