The Edgeble 6TOPS modules has configured the PCIe3.0 with - 2 lanes on Port1 of pcie3x2 controller for M.2 M-Key - 2 lanes on Port0 of pcie3x4 controller for B and E-Key The, current DT uses opposite controller nodes that indeed uses incorrect reset, regulator nodes. The configuration also uses refclk oscillator that need to enable explicitly in DT to avoid the probe hang on while reading DBI. So, this patch fixes all these essential issues and make this PCIe work properly. Issues fixed are, - Fix the associate controller nodes for M and B, E-Key - Fix the reset gpio handlings - Fix the regulator handlings and naming convensions - Support pcie_refclk oscillator Fixes:92eaee21ab("arm64: dts: rockchip: Add Edgeble NCM6A-IO M.2 B-Key, E-Key") Fixes:5d85d4c7e0("arm64: dts: rockchip: Add Edgeble NCM6A-IO M.2 M-Key") Reported-by: Mitchell Ma <machuang@radxa.com> Co-developed-by: Mitchell Ma <machuang@radxa.com> Signed-off-by: Jagan Teki <jagan@edgeble.ai> Link: https://lore.kernel.org/r/20241221151758.345257-1-jagan@edgeble.ai Signed-off-by: Heiko Stuebner <heiko@sntech.de>
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.
