This patch fixes the DP audio and video PLL configurations for the zynqmp-sm-k26-revA som. It needs to be applied for both the kv260 and kr260 starter kits. The Linux DP driver expects the DP to be using the following PLL config: - DP video PLL should use the VPLL (0x0) - DP audio PLL should use the RPLL (0x3) - DP system time clock PLL should use RPLL (0x3) Register 0xFD1A0070 configures the DP video PLL. Register 0xFD1A0074 configures the DP audio PLL. Register 0xFD1A007C configures the DP system time clock PLL. This patch was build and run tested on a zynqmp-kria-kv260 target board. Upstream-Status: submitted (https://lore.kernel.org/all/fa7e9abc419c9d7648405d1c62367dbe701d09b8.1652709736.git.michal.simek@amd.com/) This patch will be removed from buildroot in a future release when no longer necessary.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
