15   ADI is the abbreviation of Anolog-Digital interface, which is used to access
16   analog chip (such as PMIC) from digital chip. ADI controller follows the SPI
28   Thus we introduce one property named "sprd,hw-channels" to configure hardware
33   Since we have multi-subsystems will use unique ADI to access analog chip, when
