[PATCH v3 00/12] ADD USB3.1 HOST, Peri and DRD support

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



This patch series aims to add USB3.1 HOST, Peri and DRD support
on RZ/V2M EVK platform.

The reset for both host and peri are located in USB3DRD block. The
USB3DRD registers are mapped in the AXI address space of the Peripheral
module.

RZ/V2M XHCI is similar to R-Car XHCI but it doesn't require any
firmware.

Host/device needs to do reset release and set the host/device function
on DRD module, before accessing any registers.

v2->v3:
 * Fixed the X86 compilation for allmodconfig.
 * Added Rb and Acked-by tag from Rob for all the binding patches.
 * Changed USB_RZV2M_USB3DRD config option type from bool->tristate
 * Updated default values for the USB_RZV2M_USB3DRD config option
 * Updated USB_XHCI_PLATFORM to select USB_XHCI_RZV2M if ARCH_R9A09G011
   enabled.
v1->v2:
 * Added Rb tag from Rob for host binding patch
 * Renamed clock-name from "host_axi"->"axi"
 * Drop quotes around usb-xhci.yaml.
 * Moved DRD interrupts from device ctrlr to DRD bindings
 * Updated interrupts and dropped interrupt-names in device ctrlr bindings
 * Renamed aclk->axi in device ctrlr bindings
 * Added DRD interrupts and interrupt-names in DRD bindings
 * Dropped peripheral reset and reset-names from DRD bindings
 * Added reg property for usb3 device ctrlr nodes
 * Renamed peri_axi->axi and apb->reg
 * Updated pattern properties and example.
 * Moved header file from include/linux/soc/renesas->include/linux/usb
 * Passing DRD irq resource from parent to usb3_peri for handling it.
 * As drd reg is now separated from usb3 peri, updated DRD reg handling in
   usb3 peri driver.
 * Removed usb3 peri reset handling from DRD driver.
 * Added Rb tag from Geert for reset and clock updates for xhci-plat.
