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
17 framework for its hardware implementation is alike to SPI bus and its timing
18 is compatile to SPI timing.
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
