SW can trigger MIPI pads calibration any time after power on but calibration results will be latched and applied to the pads by MIPI CAL unit only when the link is in LP-11 state and then status register will be updated. For CSI, trigger of pads calibration happen during CSI stream enable where CSI receiver is kept ready prior to sensor or CSI transmitter stream start. So, pads may not be in LP-11 at this time and waiting for the calibration to be done immediate after calibration start will result in timeout. This patch splits tegra_mipi_calibrate() and tegra_mipi_wait() so triggering for calibration and waiting for it to complete can happen at different stages.

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.
