- DWC_USB3_NUM indicates the number of Device mode single directional endpoints, including OUT and IN endpoint 0. - DWC_USB3_NUM_IN_EPS indicates the maximum number of Device mode IN endpoints active at any time, including control endpoint 0. It's possible to configure RTL such that DWC_USB3_NUM_EPS is equal to DWC_USB3_NUM_IN_EPS. dwc3-core calculates the number of OUT endpoints as DWC_USB3_NUM minus DWC_USB3_NUM_IN_EPS. If RTL has been configured with DWC_USB3_NUM_IN_EPS equal to DWC_USB3_NUM then dwc3-core will calculate the number of OUT endpoints as zero. For example a from dwc3_core_num_eps() shows: [ 1.565000] /usb0@f01d0000: found 8 IN and 0 OUT endpoints This patch refactors the endpoint calculation down to one variable dwc->num_eps taking care to maintain the current mapping of endpoints for fixed FPGA configurations as described in Table 4-7 of version 2.60a of the DWC USB3 databook. The endpoint mapping will then be EP-OUT, EP-IN etc, up to DWC_USB3_NUM. If DWC_USB3_NUM is odd then OUT will take the extra endpoint.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
