A general comment I have is instead of writing hard-coded values to 
registers we should define at a minimum the bit-fields we use if not the 
entire set of bits-fields for the register.

The only exception to this is when we don't know what those values are - 
for example receiving a magic write sequence for a camera sensor.

In this case though we have full access to enumerate the register 
bit-fields.

Without looking at the register descriptions I guess this bit is an 
enable or a startup bit =>

#define QTBL_INFO_EN BIT(0)

I'll not go through this series reiterating this comment but, it 
certainly applies to any bit-field/register in the same => please define 
at least the bits used if not the full set of bits for register writes 
instead of using magic numbers.

Yes, we should expand the bits being set to provide better context to it. There
are few other places as well, primarily the power on/off sequences, will update it.
