2023-08-04usb: dwc3: dwc3-octeon: Convert to glue driverLadislav Michl1-1/+0
DWC3 as implemented in Cavium SoC is using UCTL bridge unit between I/O interconnect and USB controller. Currently there is no bond with dwc3 core code, so if anything goes wrong in UCTL setup dwc3 is left in reset, which leads to bus error while trying to read any device register. Thus any failure in UCTL initialization ends with kernel panic. To avoid this move Octeon DWC3 glue code from arch/mips and make it proper glue driver which is used instead of dwc3-of-simple.

2017-02-14MIPS: OCTEON: Platform support for OCTEON III USB controllerSteven J. Hill1-0/+1
Add all the necessary platform code to initialize the dwc3 USB host controller. This code initializes the clocks and performs a reset on the USB core and PHYs. The driver code in 'drivers/usb/dwc3' is where the real driver lives. Signed-off-by: Steven J.

2015-06-04of: clean-up unnecessary libfdt include pathsRob Herring1-3/+0
With the libfdt include fixups to use "" instead of <> in the latest dtc import in commit 4760597 (scripts/dtc: Update to upstream version 9d3649bd3be245c9), it is no longer necessary to add explicit include paths to use libfdt. Remove these across the kernel.

2014-12-24MIPS: OCTEON: add crypto helper functionsAaro Koskinen1-0/+1
Add crypto helper functions which are needed for kernel level usage. The code for these has been extracted from the EdgeRouter Pro GPL tarball. While at it, also delete duplicate definitions of the functions. Signed-off-by: Aaro Koskinen <[email protected]> Signed-off-by: Herbert Xu <[email protected]>
2014-09-22MIPS: Octeon: Move device-trees to arch/mips/boot/dts/Andrew Bresticker1-10/+0
Move the Octeon device-trees to arch/mips/boot/dts/ and update the Makefiles accordingly. Since Octeon requires the device-tree to be built into the kernel, select BUILTIN_DTB as well.

2013-02-01MIPS: Whitespace cleanup.Ralf Baechle1-1/+1

2012-11-30kbuild: centralize .dts->.dtb ruleStephen Warren1-3/+0
All architectures that use cmd_dtc do so in almost the same way. Create a central build rule to avoid duplication. The one difference is that most current uses of dtc build $(obj)/%.dtb from $(src)/dts/%.dts rather than building the .dtb in the same directory as the .dts file. This difference will be eliminated arch-by-arch in future patches. MIPS is the exception here; it already uses the exact same rule as the new common rule, so the duplicate is removed in this patch to avoid any conflict. arch/mips changes courtesy of Ralf Baechle. Update Documentation/kbuild to remove the explicit call to cmd_dtc from the example, now that the rule exists in a centralized location.

2012-07-23MIPS: Octeon: Add device tree source files.David Daney1-0/+13
The two device tree files octeon_3xxx.dts and octeon_68xx.dts are trimmed by code in a subsequent patch to reflect the hardware actually present on the board. To this end several properties that are not part of the declared bindings are added to aid in trimming off unwanted nodes. Since the device tree and the code that trims it are bound into the kernel binary, these 'marker' properties never escape into the wild, and are purely an implementation detail of the kernel early boot process. This is done for backwards compatibility with existing boards (identified by a board type enumeration value by their bootloaders). New boards will always pass a device tree from the bootloader, the built-in trees are ignored in this case.

These are the rest of the new files needed to add OCTEON processor support to the Linux kernel. Other than Makefile and Kconfig which should be obvious, we have: csrc-octeon.c -- Clock source driver for OCTEON. dma-octeon.c -- Helper functions for mapping DMA memory. flash_setup.c -- Register on-board flash with the MTD subsystem. octeon-irq.c -- OCTEON interrupt controller managment. octeon-memcpy.S -- Optimized memcpy() implementation. serial.c -- Register 8250 platform driver and early console. setup.c -- Early architecture initialization. smp.c -- OCTEON SMP support. octeon_switch.S -- Scheduler context switch for OCTEON. c-octeon.c -- OCTEON cache controller support. cex-oct.S -- OCTEON cache exception handler. asm/mach-cavium-octeon/*.h -- Architecture include files.
