Linux kernel source tree
48e304cc19
This was a SoC issue on LX2160A Rev1.0. eSDHC_DLLCFG1[DLL_PD_PULSE_STRETCH_SEL] must be set to 0 to get 4 delay cells in the pulse width detection logic for eMMC HS400 mode. Otherwise it would cause unexpected HS400 issue. This patch is to clear this bit always for affected SoC when reset for all, since this bit doesn't affect other speed modes.

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.
