This shows that I/O memory has never been used/working on the +old SoCs despite the region being advertised. As PCIe I/O ranges will +not be supported in newer SoCs using CP11x co-processors, let's +simply drop them. It is not harmful in any case as PCIe device drivers +can do it all with the regular mapped memory anyway. + +Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> +Signed-off-by: Gregory CLEMENT <gregory.clement@bootlin.com> +--- + arch/arm64/boot/dts/marvell/armada-70x0.dtsi | 2 -- + .../boot/dts/marvell/armada-8040-mcbin.dtsi | 3 +-- + arch/arm64/boot/dts/marvell/armada-80x0.dtsi | 4 ---- + arch/arm64/boot/dts/marvell/armada-cp11x.dtsi | 16 +++------------- + 4 files changed, 4 insertions(+), 21 deletions(-) + +--- a/arch/arm64/boot/dts/marvell/armada-70x0.dtsi ++++ b/arch/arm64/boot/dts/marvell/armada-70x0.dtsi +@@ -19,7 +19,6 @@ + */ + #define CP11X_NAME cp0 + #define CP11X_BASE f2000000 +-#define CP11X_PCIE_IO_BASE 0xf9000000 + #define CP11X_PCIE_MEM_BASE 0xf6000000 + #define CP11X_PCIE0_BASE f2600000 + #define CP11X_PCIE1_BASE f2620000 +@@ -29,7 +28,6 @@ + + #undef CP11X_NAME + #undef CP11X_BASE +-#undef CP11X_PCIE_IO_BASE + #undef CP11X_PCIE_MEM_BASE + #undef CP11X_PCIE0_BASE + #undef CP11X_PCIE1_BASE +--- a/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi ++++ b/arch/arm64/boot/dts/marvell/armada-8040-mcbin.dtsi +@@ -179,8 +179,7 @@ + num-lanes = <4>; + num-viewport = <8>; + reset-gpios = <&cp0_gpio2 20 GPIO_ACTIVE_LOW>; +- ranges = <0x81000000 0x0 0xf9010000 0x0 0xf9010000 0x0 0x10000 +- 0x82000000 0x0 0xc0000000 0x0 0xc0000000 0x0 0x20000000>; ++ ranges = <0x82000000 0x0 0xc0000000 0x0 0xc0000000 0x0 0x20000000>; + phys = <&cp0_comphy0 0>, <&cp0_comphy1 0>, + <&cp0_comphy2 0>, <&cp0_comphy3 0>; + phy-names = "cp0-pcie0-x4-lane0-phy", "cp0-pcie0-x4-lane1-phy", +--- a/arch/arm64/boot/dts/marvell/armada-80x0.dtsi ++++ b/arch/arm64/boot/dts/marvell/armada-80x0.dtsi +@@ -21,7 +21,6 @@ + */ + #define CP11X_NAME cp0 + #define CP11X_BASE f2000000 +-#define CP11X_PCIE_IO_BASE 0xf9000000 + #define CP11X_PCIE_MEM_BASE 0xf6000000 + #define CP11X_PCIE0_BASE f2600000 + #define CP11X_PCIE1_BASE f2620000 +@@ -31,7 +30,6 @@ + + #undef CP11X_NAME + #undef CP11X_BASE +-#undef CP11X_PCIE_IO_BASE + #undef CP11X_PCIE_MEM_BASE + #undef CP11X_PCIE0_BASE + #undef CP11X_PCIE1_BASE +@@ -42,7 +40,6 @@ + */ + #define CP11X_NAME cp1 + #define CP11X_BASE f4000000 +-#define CP11X_PCIE_IO_BASE 0xfd000000 + #define CP11X_PCIE_MEM_BASE 0xfa000000 + #define CP11X_PCIE0_BASE f4600000 + #define CP11X_PCIE1_BASE f4620000 +@@ -52,7 +49,6 @@ + + #undef CP11X_NAME + #undef CP11X_BASE +-#undef CP11X_PCIE_IO_BASE + #undef CP11X_PCIE_MEM_BASE + #undef CP11X_PCIE0_BASE + #undef CP11X_PCIE1_BASE +--- a/arch/arm64/boot/dts/marvell/armada-cp11x.dtsi ++++ b/arch/arm64/boot/dts/marvell/armada-cp11x.dtsi +@@ -10,7 +10,6 @@ + + #include "armada-common.dtsi" + +-#define CP11X_PCIEx_IO_BASE(iface) (CP11X_PCIE_IO_BASE + (iface * 0x10000)) + #define CP11X_PCIEx_MEM_BASE(iface) (CP11X_PCIE_MEM_BASE + (iface * 0x1000000)) + #define CP11X_PCIEx_CONF_BASE(iface) (CP11X_PCIEx_MEM_BASE(iface) + 0xf00000) + +@@ -507,11 +506,8 @@ + msi-parent = <&gic_v2m0>; + + bus-range = <0 0xff>; +- ranges = +- /* downstream I/O */ +- <0x81000000 0 CP11X_PCIEx_IO_BASE(0) 0 CP11X_PCIEx_IO_BASE(0) 0 0x10000 + /* non-prefetchable memory */ +- 0x82000000 0 CP11X_PCIEx_MEM_BASE(0) 0 CP11X_PCIEx_MEM_BASE(0) 0 0xf00000>; ++ ranges = <0x82000000 0 CP11X_PCIEx_MEM_BASE(0) 0 CP11X_PCIEx_MEM_BASE(0) 0 0xf00000>; + interrupt-map-mask = <0 0 0 0>; + interrupt-map = <0 0 0 0 &CP11X_LABEL(icu_nsr) 22 IRQ_TYPE_LEVEL_HIGH>; + interrupts = <22 IRQ_TYPE_LEVEL_HIGH>; +@@ -534,11 +530,8 @@ + msi-parent = <&gic_v2m0>; + + bus-range = <0 0xff>; +- ranges = +- /* downstream I/O */ +- <0x81000000 0 CP11X_PCIEx_IO_BASE(1) 0 CP11X_PCIEx_IO_BASE(1) 0 0x10000 + /* non-prefetchable memory */ +- 0x82000000 0 CP11X_PCIEx_MEM_BASE(1) 0 CP11X_PCIEx_MEM_BASE(1) 0 0xf00000>; ++ ranges = <0x82000000 0 CP11X_PCIEx_MEM_BASE(1) 0 CP11X_PCIEx_MEM_BASE(1) 0 0xf00000>; + interrupt-map-mask = <0 0 0 0>; + interrupt-map = <0 0 0 0 &CP11X_LABEL(icu_nsr) 24 IRQ_TYPE_LEVEL_HIGH>; + interrupts = <24 IRQ_TYPE_LEVEL_HIGH>; +@@ -562,11 +555,8 @@ + msi-parent = <&gic_v2m0>; + + bus-range = <0 0xff>; +- ranges = +- /* downstream I/O */ +- <0x81000000 0 CP11X_PCIEx_IO_BASE(2) 0 CP11X_PCIEx_IO_BASE(2) 0 0x10000 + /* non-prefetchable memory */ +- 0x82000000 0 CP11X_PCIEx_MEM_BASE(2) 0 CP11X_PCIEx_MEM_BASE(2) 0 0xf00000>; ++ ranges = <0x82000000 0 CP11X_PCIEx_MEM_BASE(2) 0 CP11X_PCIEx_MEM_BASE(2) 0 0xf00000>; + interrupt-map-mask = <0 0 0 0>; + interrupt-map = <0 0 0 0 &CP11X_LABEL(icu_nsr) 23 IRQ_TYPE_LEVEL_HIGH>; + interrupts = <23 IRQ_TYPE_LEVEL_HIGH>; |
