Linux kernel source tree
2cef35958d
Move the implementation of platform specific power well hooks to intel_display_power_well.c, to reduce the clutter in intel_display_power.c. The locking of all the power domain/power well state is handled in the power domain functions in intel_display_power.c using i915_power_domains::lock. This patch also moves the chy_phy_powergate_ch/lanes() functions to intel_display_power_well.c which borrow the same lock to protect the DISPLAY_PHY_CONTROL register state, which the HW uses both for toggling power wells and power gating PHY lanes. No functional change. v2: - Clarify in the commit log why CHV functions using the i915_power_domains::lock were moved, while others locking the power domain/well state were kept in intel_display_power.c . (Jouni) - Move forward declaration of chv_phy_powergate_ch/lanes() to intel_display_power_well.h .

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.
