Linux kernel source tree
660c396c98
Ordering issues here cause an uninitialized (default STANDALONE)
usecase to be programmed (which appears to be a MUX) in some cases
when msm_dsi_host_register() is called, leading to the slave PLL in
bonded-DSI mode to source from a clock parent (dsi1vco) that is off.
This should seemingly not be a problem as the actual dispcc clocks from
DSI1 that are muxed in the clock tree of DSI0 are way further down, this
bit still seems to have an effect on them somehow and causes the right
side of the panel controlled by DSI1 to not function.
In an ideal world this code is refactored to no longer have such
error-prone calls "across subsystems", and instead model the "PLL src"
register field as a regular mux so that changing the clock parents
programmatically or in DTS via `assigned-clock-parents` has the
desired effect.
But for the avid reader, the clocks that we *are* muxing into DSI0's
tree are way further down, so if this bit turns out to be a simple mux
between dsiXvco and out_div, that shouldn't have any effect as this
whole tree is off anyway.

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.
