Linux kernel source tree
ebf877a51a
Previously when the user gets a FPGA manager, it was locked and nobody else could use it for programming. This commit makes it straightforward to save a reference to an FPGA manager and only lock it when programming the FPGA. Add functions that get an FPGA manager's mutex for exclusive use: * fpga_mgr_lock * fpga_mgr_unlock The following functions no longer lock an FPGA manager's mutex: * of_fpga_mgr_get * fpga_mgr_get * fpga_mgr_put Signed-off-by: Alan Tull <atull@kernel.org> Acked-by: Moritz Fischer <mdf@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
