splitting the mcp node in two without also -modifying the second half from the addr parameter would cause the two -halves to separate. Change the implementation strategy to patch -fragment 2 (as was originally proposed). This will prevent the -overlay from being applied at runtime until the "dtoverlay" command -is improved, but the overlay already has this restriction due to -fragment 3 so this isn't a step backwards. - -See: https://github.com/raspberrypi/linux/issues/3449 - -Signed-off-by: Phil Elwell ---- - arch/arm/boot/dts/overlays/mcp23017-overlay.dts | 16 +++++++--------- - 1 file changed, 7 insertions(+), 9 deletions(-) - ---- a/arch/arm/boot/dts/overlays/mcp23017-overlay.dts -+++ b/arch/arm/boot/dts/overlays/mcp23017-overlay.dts -@@ -48,15 +48,13 @@ - };

The possible values go from 16MB +to 944MB, with a default of 64MB. This memory resides in the topmost +part of the lower 1GB memory area and grows bigger expanding towards the +begging of memory. + +It turns out that with low 'gpu_mem' values (16MB and 32MB) the size of +the memory available to the system in the lower 1GB area can outgrow the +interconnect's dma-range as its size was selected based on the maximum +system memory available given the default gpu_mem configuration. This +makes that memory slice unavailable for DMA. And may cause nasty kernel +warnings if CMA happens to include it. + +Change soc's dma-ranges to really reflect it's HW limitation, which is +being able to only DMA to the lower 1GB area. + +Fixes: 7dbe8c62ceeb ("ARM: dts: Add minimal Raspberry Pi 4 support") +Signed-off-by: Nicolas Saenz Julienne +Reviewed-by: Phil Elwell +Signed-off-by: Florian Fainelli +--- + arch/arm/boot/dts/bcm2711.dtsi | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/arch/arm/boot/dts/bcm2711.dtsi ++++ b/arch/arm/boot/dts/bcm2711.dtsi +@@ -43,7 +43,7 @@ + <0x7c000000 0x0 0xfc000000 0x02000000>, + <0x40000000 0x0 0xff800000 0x00800000>;

The offset between physical memory +addresses and AMBA's view is provided by reading a PCI config register, +which is saved and used whenever DMA mapping is needed. + +It turns out that this DMA setup can be represented by properly setting +'dma_pfn_offset', 'dma_bus_mask' and 'dma_mask' during the PCI device +enable fixup. And ultimately allows us to get rid of this device's +custom DMA functions. + +Aside from the code deletion and DMA setup, sta2x11_pdev_to_mapping() is +moved to avoid warnings whenever CONFIG_PM is not enabled. + +Signed-off-by: Nicolas Saenz Julienne +Signed-off-by: Christoph Hellwig +--- + arch/x86/Kconfig | 1 - + arch/x86/include/asm/device.h | 3 - + arch/x86/include/asm/dma-direct.h | 9 -- + arch/x86/pci/sta2x11-fixup.c | 135 ++++++------------------------ + 4 files changed, 26 insertions(+), 122 deletions(-) + delete mode 100644 arch/x86/include/asm/dma-direct.h + +--- a/arch/x86/Kconfig ++++ b/arch/x86/Kconfig +@@ -708,7 +708,6 @@ config X86_SUPPORTS_MEMORY_FAILURE + config STA2X11 + bool "STA2X11 Companion Chip Support" + depends on X86_32_NON_STANDARD && PCI +- select ARCH_HAS_PHYS_TO_DMA + select SWIOTLB + select MFD_STA2X11 + select GPIOLIB +--- a/arch/x86/include/asm/device.h ++++ b/arch/x86/include/asm/device.h +@@ -6,9 +6,6 @@ struct dev_archdata { + #if defined(CONFIG_INTEL_IOMMU) || defined(CONFIG_AMD_IOMMU) + void *iommu;

The -DMA mapping code is already aware of this and treats dev->bus_dma_mask -as a limit. This quirk is already used by some architectures although -still rare. - -With the introduction of the Raspberry Pi 4 we've found a new contender -for the use of bus DMA limits, as its PCIe bus can only address the -lower 3GB of memory (of a total of 4GB). This is impossible to represent -with a mask. To make things worse the device-tree code rounds non power -of two bus DMA limits to the next power of two, which is unacceptable in -this case. - -In the light of this, rename dev->bus_dma_mask to dev->bus_dma_limit all -over the tree and treat it as such.
