15   ADI is the abbreviation of Anolog-Digital interface, which is used to access
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
38   Then we need one hardware spinlock to synchronize between the multiple subsystems.
