commitec33745bccupstream. Commit225da7e65a("ARM: dts: add eMMC reset line for exynos4412-odroid-common") added MMC power sequence for eMMC card of Odroid X2/U3. It reused generic sd1_cd pin control configuration node and only disabled pull-up. However that time the pinctrl configuration was not applied during MMC power sequence driver initialization. This has been changed later by commitd97a1e5d7c("mmc: pwrseq: convert to proper platform device"). It turned out then, that the provided pinctrl configuration is not correct, because the eMMC_RTSN line is being re-configured as 'special function/card detect function for mmc1 controller' not the simple 'output', thus the power sequence driver doesn't really set the pin value. This in effect broke the reboot of Odroid X2/U3 boards. Fix this by providing separate node with eMMC_RTSN pin configuration.

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.
