Douglas Anderson 148ddaa89d clk: qcom: gcc-sc7180: Use floor ops for the correct sdcc1 clk 
While picking commit a8cd989e1a ("mmc: sdhci-msm: Warn about
overclocking SD/MMC") back to my tree I was surprised that it was
reporting warnings.  I thought I fixed those!  Looking closer at the
fix, I see that I totally bungled it (or at least I halfway bungled
it).  The SD card clock got fixed (and that was the one I was really
focused on fixing), but I totally adjusted the wrong clock for eMMC.
Sigh.  Let's fix my dumb mistake.

Now both SD and eMMC have floor for the "apps" clock.

This doesn't matter a lot for the final clock rate for HS400 eMMC but
could matter if someone happens to put some slower eMMC on a sc7180.
We also transition through some of these lower rates sometimes and
having them wrong could cause problems during these transitions.
These were the messages I was seeing at boot:
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
  mmc1: Card appears overclocked; req 52000000 Hz, actual 100000000 Hz
  mmc1: Card appears overclocked; req 104000000 Hz, actual 192000000 Hz

README 

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.
