Driver needs payload/header credits for sending any command and data over DSI link. These credits are released once command or data sent to link. This patch adds functions to wait for releasing of payload and header credits. As per BSPEC, driver needs to ensure that all of commands/data has been dispatched to panel before the transcoder is enabled. This patch implement those steps i.e. sending NOP DCS command, wait for header/payload credit to be released etc. v2 by Jani: - squash the credit wait helpers patch with the first user - pass dev_priv to the credit wait helpers - bikeshed credit helper names - wait for *at least* the current maximum number of credits - indentation fix - add helpers for credits available Signed-off-by: Madhav Chauhan <madhav.chauhan@intel.com> Signed-off-by: Jani Nikula <jani.nikula@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/84bc509beabf2a2d1324a9f2a67ab4ebe05b10a6.1540900289.git.jani.nikula@intel.com
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.
