For LSB bits, I dont think this is an issue. I expect it to work, for example:
#define CONTROL_LSB_MASK GENMASK(2, 0)
foo |= u32_encode_bits(control, CONTROL_LSB_MASK);
would mask the control value and program that in specific bitfeild.
But for MSB bits, I am not sure above will

description to Documentation (that can come as an individual patch),
ok

a hierarchical encoding to interface with Class-defined capabilities.
The specification is not yet accessible to the general public but this
information is released with explicit permission from the MIPI Board
