According to the datasheet of Meson8b (S805) and GXBB (S905) the decoding mode is configured in AO_MF_IR_DEC_REG2 (offset 0x20) using bits 0-3. The "duration" field may not be set correctly when any of the hardware decoding modes. This can happen while a "default" decoding mode (either set by the bootloader or the chip's default, which uses NEC as it's default) is used. While here, I also added defines for the protocols which can be decoded by the hardware (more work is needed to be actually able to use them though).
