[Kernel-packages] [Bug 2055241] Re: Update on-chip oscillator clock nodes for Kria

[Sagar Karmarkar]

Hi @Portia

I verified the update of on chip oscillators clock nodes for Kria, with
the above 1029.33 kernel. Everything working as expected and all good
there.

Thanks

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

[Kernel-packages] [Bug 2058707] Re: Backport AXI 1-wire host driver

[Sagar Karmarkar]

Hi @Portia

I verified the working of AXI 1-wire with the above 1029.33 kernel.
Everything working as expected and all good there.

Thanks

   Backport AXI 1-wire host driver

Bug description:
  [ Impact ]

  * Backport AXI 1-wire host driver.
  * The driver is used to interface with FPGA IP logic.
  * The driver is only loaded when device tree overlay is applied on platforms 
that require the driver.

  [ Test Plan ]

  * Xilinx will test the functionality on a KD240 with an FPGA bitstream
  that has the required IP logic.

  [ Where problems could occur ]

  * We are unable to run certification testing with the driver loaded
  which creates a risk of breaking the driver in the future.
