As per BSEPC, if device ready bit is '0' in enable IO sequence then its a cold boot/reset scenario eg: S3/S4 resume. If cold boot scenario detected in enable IO, then prepare port immediately. In normal boot scenario, prepare port after glk_dsi_device_ready(). Without cold boot sequence enabled, features like S3/S4 doesn't work.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
