So absolutely *no* register macros with boolean flags to shift or
not. Just no.
This is totally unreadable.
Define the macros in terms of the REG_FIELD_MASK and REG_FIELD_PREP, and
use REG_FIELD_GET to read the values.
#define DSC_PIC_WIDTH(pic_width) REG_FIELD_PREP(DSC_PIC_WIDTH_MASK, pic_width)
pps_val |= DSC_PIC_WIDTH(vdsc_cfg->pic_width / num_vdsc_instances)
This should probably be a first cleanup patch before the other changes.

The comments may be helpful as headings, but a simple /* PPS 0 */ etc
will do.

Please define the read function so that you don't have to initialize
this to zero every time.

Use REG_FIELD_GET(), throw out the shifts.

For assigning booleans just pps_temp & DSC_BLOCK_PREDICTION is
enough. The ternary operator is superfluous. Ditto below.

This is the way to go:
vdsc_cfg->pic_width = REG_FIELD_GET(DSC_PIC_WIDTH_MASK, pps_temp);
> + vdsc_cfg->pic_height = pps_temp & ~DSC_PIC_WIDTH_MASK;
Nope, just use REG_FIELD_GET() for all of it.
