usb: cdns3: Adds missing __iomem markers

2021-01-14T01:01:33+00:00

Patch adds missing __iomem markers in core.h file and makes some changes in drd.c file related with these markers. The lack of __iomem has reported by sparse checker on parsic architecture. Reported-by: kernel test robot Signed-off-by: Pawel Laszczak Signed-off-by: Peter Chen

usb: cdnsp: cdns3 Add main part of Cadence USBSSP DRD Driver

2020-12-29T04:36:13+00:00

This patch introduces the main part of Cadence USBSSP DRD driver to Linux kernel. To reduce the patch size a little bit, the header file gadget.h was intentionally added as separate patch. The Cadence USBSSP DRD Controller is a highly configurable IP Core which can be instantiated as Dual-Role Device (DRD), Peripheral Only and Host Only (XHCI)configurations. The current driver has been validated with FPGA platform. We have support for PCIe bus, which is used on FPGA prototyping. The host side of USBSS DRD controller is compliant with XHCI. The architecture for device side is almost the same as for host side, and most of the XHCI specification can be used to understand how this controller operates.

usb: cdns3: Changed type of gadget_dev in cdns structure

2020-12-29T04:36:13+00:00

Patch changes the type for gadget_dev pointer in cdns structure from pointer to cdns3_device structure to void pointer. This filed is in reusable code and after this change it will be used to point to both cdns3_device or cdnsp_device objects.

usb: cdns3: Refactoring names in reusable code

2020-12-29T04:36:13+00:00

Patch change the functions and objects names in reusable code. The reusable code includes core.c, core.h, drd.c and drd.h files. It also changes the names of all references to these functions and objects in other cdns3 files. There are a lot of changes, but all changes are very trivial. The reason of this patch is to avoid of mixing prefix cdns3 and cdnsp in in cdnsp driver what could introduce some confusion in understanding of cdnsp driver. This patch assumes to use three different prefixes in Cadence USB drivers: cdns: for common reusable code cdnsp: for names related only with cdnsp driver cdns3: for names related only with cdns3 driver Signed-off-by: Pawel Laszczak Tested-by: Aswath Govindraju Signed-off-by: Peter Chen

usb: cdns3: Moves reusable code to separate module

2020-12-29T04:36:13+00:00

Patch moves common reusable code used by cdns3 and cdnsp driver to cdns-usb-common library. This library include core.c, drd.c and host.c files. Signed-off-by: Pawel Laszczak Tested-by: Aswath Govindraju Signed-off-by: Peter Chen

usb: cdns3: Split core.c into cdns3-plat and core.c file

2020-12-29T04:36:13+00:00

Patch splits file core.c into core.c containing the common reusable code and cnd3-plat.c containing device platform specific code. These changes are required to make possible reuse DRD part of CDNS3 driver in CDNSP driver. Signed-off-by: Pawel Laszczak Tested-by: Aswath Govindraju Signed-off-by: Peter Chen

usb: cdns3: Add support for DRD CDNSP

2020-12-29T04:36:13+00:00

Patch adds support for Cadence DRD Super Speed Plus controller(CDNSP). CDNSP DRD is a part of Cadence CDNSP controller. The DRD CDNSP controller has a lot of difference on hardware level but on software level is quite compatible with CDNS3 DRD. For this reason CDNS3 DRD part of CDNS3 driver was reused for CDNSP driver. Signed-off-by: Pawel Laszczak Tested-by: Aswath Govindraju Signed-off-by: Peter Chen

usb: cdns3: add quirk for enable runtime pm by default
