RSS Bot Posted January 3 Posted January 3 Description The Orange Pi Zero 3 board was recently added as a WIP configuration, and through testing it was determined that the CPU frequency configuration was not working for this board, but was working correctly for the Orange Pi Zero 2. Further investigation determined that the h618 CPU (which differs from the Zero 2 h616) was not in the allow list in the CPU frequency kernel driver. This PR updates both the current and edge sunxi kernel configurations with a patch that enables the h618 device in the configuration whitelist. The goal of this patch was to make the smallest change possible change to the driver code to enable the capability for the Zero 3. In the code, the h618, once enabled/allowed, references the existing h616 configuration. Jira reference number [N/A] How Has This Been Tested?
