16 ADI is the abbreviation of Anolog-Digital interface, which is used to access
17 analog chip (such as PMIC) from digital chip. ADI controller follows the SPI
21 ADI controller has 50 channels including 2 software read/write channels and
22 48 hardware channels to access analog chip. For 2 software read/write channels,
23 users should set ADI registers to access analog chip. For hardware channels,
25 which means we can just link one analog chip address to one hardware channel,
26 then users can access the mapped analog chip address by this hardware channel
29 Thus we introduce one property named "sprd,hw-channels" to configure hardware
30 channels, the first value specifies the hardware channel id which is used to
32 the analog chip address where user want to access by hardware components.
34 Since we have multi-subsystems will use unique ADI to access analog chip, when
