This patch adds +the driver that allows us to use the EBU as a PCI controller. In order for +PCI to work the EBU is set to endianess swap all the data. In addition we +need to make use of SWAP_IO_SPACE for device->host DMA to work. + +The clock of the PCI works in several modes (internal/external). If this +is not configured correctly the SoC will hang. + +Signed-off-by: John Crispin <blogic@openwrt.org> +Signed-off-by: Ralph Hempel <ralph.hempel@lantiq.com> +Cc: linux-mips@linux-mips.org +Patchwork: https://patchwork.linux-mips.org/patch/2250/ +Signed-off-by: Ralf Baechle <ralf@linux-mips.org> +--- + .../mips/include/asm/mach-lantiq/lantiq_platform.h | 46 +++ + arch/mips/pci/Makefile | 1 + + arch/mips/pci/ops-lantiq.c | 116 ++++++++ + arch/mips/pci/pci-lantiq.c | 297 ++++++++++++++++++++ + arch/mips/pci/pci-lantiq.h | 18 ++ + 5 files changed, 478 insertions(+), 0 deletions(-) + create mode 100644 arch/mips/include/asm/mach-lantiq/lantiq_platform.h + create mode 100644 arch/mips/pci/ops-lantiq.c + create mode 100644 arch/mips/pci/pci-lantiq.c + create mode 100644 arch/mips/pci/pci-lantiq.h + +diff --git a/arch/mips/include/asm/mach-lantiq/lantiq_platform.h b/arch/mips/include/asm/mach-lantiq/lantiq_platform.h +new file mode 100644 +index 0000000..1f1dba6 +--- /dev/null ++++ b/arch/mips/include/asm/mach-lantiq/lantiq_platform.h +@@ -0,0 +1,46 @@ ++/* ++ * This program is free software;

This patch adds +the driver that allows us to use the EBU as a PCI controller. In order for +PCI to work the EBU is set to endianess swap all the data. In addition we +need to make use of SWAP_IO_SPACE for device->host DMA to work. + +The clock of the PCI works in several modes (internal/external).

This module will be dynamically installed ++ * after Linux is booted using the insmod command. When the module is ++ * installed, the dwc_otg_init function is called. When the module is ++ * removed (using rmmod), the dwc_otg_cleanup function is called. ++ * ++ * This module also defines a data structure for the dwc_otg_driver, which is ++ * used in conjunction with the standard ARM lm_device structure.
