Hello,
This patch introduces the SMC calls for MediaTek APU.
The start and stop sequences of the APU microprocessor are managed within the ARM Trusted Firmware (ATF), which requires a secure and reliable communication channel to issue commands from the non-secure world. This patch adds the necessary infrastructure to issue these SMC calls, ensuring that the APU can be securely managed by the system's software.
Please review and provide feedback.
Best regards
---
Changes in v2:
- Move header file to include/linux/firmware/mediatek/
- Rename header file name to mtk-apu.h
- Update define macro name to __MEDIATEK

Add command for APU SMC call.
The APU microprocess's start and stop sequence will process in ATF.
