10 users should set ADI registers to access analog chip. For hardware channels,
11 we can configure them to allow other hardware components to use it independently,
12 which means we can just link one analog chip address to one hardware channel,
13 then users can access the mapped analog chip address by this hardware channel
14 triggered by hardware components instead of ADI software channels.
16 Thus we introduce one property named "sprd,hw-channels" to configure hardware
