Title:
Update on-chip oscillator clock nodes for Kria
Status in linux-xilinx-zynqmp package in Ubuntu:
New
Status in linux-xilinx-zynqmp source package in Jammy:
Fix Committed
Bug description:
[ Impact ]
* This models on-chip oscillator clock nodes in KV/KR/KD board device trees
built for Xilinx products to be in sync with the corresponding board schematic
* Currently a few clocks were not modelled which are planned to be included
now.
* Most clocks in board device trees are currently included so this should
have minimal size impact.
* The correct and cleanest approach is to model clock sources in Xilinx's
application dtsi's in order to reference these clock nodes from the board
device tree rather than having duplicated nodes in application overlay dtbo's
[ Test Plan ]
* Normal certification will test that the device tree changes did not
introduce a regression on any certified platform.
* Xilinx will verify they can load the dtbo's for the FPGA during runtime
[ Where problems could occur ]
* There could be an unexpected impact since there are discrepancies
between some revA vs revB board device trees, all clock nodes not
being modelled to be in sync with board schematics
[ Other Info ]
* Changes are pulled from Xilinx' 6.6 tree
