Subject: [PATCH v2 0/2] usb: dwc3: Introduce DWC_usb32 IP
Date: Sat, 11 Apr 2020 19:19:54 -0700 [thread overview]
Message-ID: <cover.1586657326.git.thinhn@synopsys.com> (raw)
This patch series adds support to Synopsys DWC_usb32 controller. The controller
supports dual-lane and speed up to 20 Gbps, and the DWC3 driver will drive this
controller.
The configuration and programming model for DWC_usb32 is very similar to
DWC_usb31 and DWC_usb30. This series is one of the first sets, and it only
includes the necessary changes to recognize, initialize, and run DWC_usb32. It
includes:
* New IP checking scheme
* IP Checks for DWC_usb32
* New MDWIDTH parameter for DWC_usb32
The change to support lane count and lane speed mantissa will come in a
separate series. Hopefully this helps simplify the review process and help push
the change in steps.
This series is base off of Felipe's testing/next branch:
https://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git/log/?h=testing/next
It also depends on the following patches in Felipe's testing/fixes branch:
usb: dwc3: Fix GTXFIFOSIZ.TXFDEP macro name
usb: dwc3: gadget: Properly set maxpacket limit
https://patchwork.kernel.org/cover/11283761/
https://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb.git/log/?h=testing/fixes
Changes in v2:
- Change the macro to avoid constant to constant comparison static analysis
warnings. (DWC3x_VERSION_ANY == DWC3x_VERSION_XXX) => !(DWC3x_VERSION_XXX)
