Linux kernel source tree

The PCIE_CTRL registers within the CTRL_MMR space of TI's J784S4 SoC are used to configure the link speed, lane count and mode of operation of the respective PCIe instance. Add compatible for allowing the PCIe driver to obtain a regmap for the PCIE_CTRL register within the System Controller device-tree node in order to configure the PCIe instance accordingly. The Technical Reference Manual for J784S4 SoC with details of the PCIE_CTRL registers is available at: https://www.ti.com/lit/zip/spruj52 Signed-off-by: Siddharth Vadapalli <s-vadapalli@ti.com> Acked-by: Krzysztof Kozlowski <krzysztof.kozlowski@linaro.org> Link: https://lore.kernel.org/r/20240204090336.3209063-1-s-vadapalli@ti.com Signed-off-by: Lee Jones <lee@kernel.org> |

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.
