The T-Head TH1520 SoC uses an E902 co-processor running Always-On (AON) firmware to manage power, clock, and other system resources [1]. This patch introduces a driver implementing the AON firmware protocol, allowing the Linux kernel to communicate with the firmware via mailbox channels. Through an RPC-based interface, the kernel can initiate power state transitions, update resource configurations, and perform other AON-related tasks.
