Move away from using deprecated API and use _multi
variants if available. Use mipi_dsi_msleep()
and mipi_dsi_usleep_range() instead of msleep()
and usleep_range() respectively.
Used Coccinelle to find the _multi variant APIs,
replacing mpi_dsi_msleep() where necessary and for returning
dsi_ctx.accum_err in these functions. Manually handled the
reset step before returning from r63353_panel_activate()
v2: Do not skip the reset in case of error during
panel activate (Dmitry)
- Convert all usleep_range()
v3: mipi_dsi_usleep_range() is to be used only when in
between _multi commands(Doug)
- Check for error once in the end while using _multi
variants (Doug)
v4: Change return type of r63353_panel_deactivate() to void (Doug)

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 reStructuredText 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.
