the mmci driver (drivers/mmc/host/mmci.c) does the following sequence: * clk_prepare_enable() * clk_set_rate() on SDCx_clk which is a children of SDCx_src. SDCx_src has CLK_SET_RATE_GATE so this sequence should not be allowed but this was not enforced. IOW, the flag is ignored. Dropping the flag won't change anything to the current behaviour of the platform. CLK_SET_RATE_GATE is being fixed and enforced now. If the flag was kept, the mmci driver would receive -EBUSY when calling clk_set_rate() Signed-off-by: Jerome Brunet <jbrunet@baylibre.com> Signed-off-by: Michael Turquette <mturquette@baylibre.com> Link: lkml.kernel.org/r/20180619134051.16726-2-jbrunet@baylibre.com
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.
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.
