The busy timeout for the CMD5 to put the eMMC into sleep state, is specific to the card. Potentially the timeout may exceed the host->max_busy_timeout. If that becomes the case, mmc_sleep() converts from using an R1B response to an R1 response, as to prevent the host from doing HW busy detection. However, it has turned out that some hosts requires an R1B response no matter what, so let's respect that via checking MMC_CAP_NEED_RSP_BUSY. Note that, if the R1B gets enforced, the host becomes fully responsible of managing the needed busy timeout, in one way or the other.

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.
