usb: cdnsp: fixed issue with incorrect detecting CDNSP family controllers

2024-02-19T08:30:41Z

Cadence have several controllers from 0x000403xx family but current driver suuport detecting only one with DID equal 0x0004034E. It causes that if someone uses different CDNSP controller then driver will use incorrect version and register space.

usb: cdns3: Add PHY mode switch to usb2 PHY

2023-07-25T16:22:36Z

cdns3 just set PHY mode switch for USB3.0 PHY. If USB 2.0 PHY contains PHY mode switch setting, USB 2.0 PHY mode function can't be called. So add PHY mode switch function for USB 2.0 PHY.

If the controller lost its power during the system suspend, we need to do all initialiation operations. Signed-off-by: Peter Chen Signed-off-by: Frank Li Signed-off-by: Peter Chen

usb: cdns3: Adds missing __iomem markers

2021-01-14T01:01:33Z

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

2020-12-29T04:36:13Z

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: Refactoring names in reusable code

2020-12-29T04:36:13Z

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
