PetaLinux 2015.2 - Device Tree Generator Incorrectly Sets FCLK Property to 0 Even When Design Uses FCLKs


My design exposes Processing System-generated FCLK sources to logic in the programmable logic.

In the automatically generated device tree, the "fclk" property is set to 0 rather than 1.


This issue occurs because the device tree generator logic is failing to detect the presence of the FCLKs.

Specifically, it is searching for signals named "FCLK" rather than "FCLK_CLK".

This issue is resolved in the PetaLinux 2015.2.1 release.
