Marek Szyprowski bb57453d6a drm: exynos: dsi: Handle proper host initialization
Host transfer() in the DSI master will invoke only when the DSI commands
are sent from DSI devices like DSI Panel or DSI bridges and this host
the transfer wouldn't invoke for I2C-based-DSI bridge drivers.

Handling DSI host initialization in transfer calls misses the controller
setup for I2C configured DSI bridges.

This patch updates the DSI host initialization by calling host to init
from bridge pre_enable as the bridge pre_enable API is invoked by core
as it is common across all classes of DSI device drivers.

The host init during pre_enable is conditional and not invoked for Exynos
as existing downstream drm panels and bridges in Exynos are expecting
the host initialization during DSI transfer.

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.
