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 Karl Li (1): soc: mediatek: Add command for APU SMC call include/linux/firmware/mediatek/mtk-apu.h | 32 +++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 include/linux/firmware/mediatek/mtk-apu.h
