Some devices have USB compositions which may require multiple endpoints. To get better performance, need bigger CDNS3_EP_BUF_SIZE. But bigger CDNS3_EP_BUF_SIZE may exceed total hardware FIFO size when multiple endpoints. By introducing the check_config() callback, calculate CDNS3_EP_BUF_SIZE. Move CDNS3_EP_BUF_SIZE into cnds3_device: ep_buf_size Combine CDNS3_EP_ISO_SS_BURST and CDNS3_EP_ISO_HS_MULT into cnds3_device:ep_iso_burst Using a simple algorithm to calculate ep_buf_size. ep_buf_size = ep_iso_burst = (onchip_buffers - 2k) / (number of IN EP + 1). Test at 8qxp: Gadget ep_buf_size RNDIS: 5 RNDIS+ACM: 3 Mass Storage + NCM + ACM 2 Previous CDNS3_EP_BUF_SIZE is 4, RNDIS + ACM will be failure because exceed FIFO memory.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
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.
