Vandita Kulkarni 26fb0d552d drm/i915/dsi: Initiate frame request in cmd mode
In TE Gate mode or TE NO_GATE mode on every flip we need to set the
frame update request bit. After this bit is set transcoder hardware will
automatically send the frame data to the panel in case of TE NO_GATE
mode, where it sends after it receives the TE event in case of TE_GATE
mode. Once the frame data is sent to the panel, we see the frame counter
updating.

v2: Use intel_de_read/write

v3: remove the usage of private_flags

v4: Use icl_dsi in func names if non static,
    fix code formatting issues. (Jani)

v5: Send frame update request at the beginning of
    pipe_update_end, use crtc_state mode_flags (Ville)

v6: Add platform and dsi checks (Ville)

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.
