Detailed Description

D-PHY PLL coefficients written into DPHYPLFCR.

Caller supplies pre-validated coefficients. The driver packs them into DPHYPLFCR per HUM Ch 64.2.2 p 3823 and validates against the PMUL band table on p 3824 before committing.

Final PLL output: f = f_main * (1/IDIV) * (NMUL_int + NFMUL_frac) * (1/PMUL). Line rate per lane = f / 2 (HUM 64.2.2 p 3824).

cppcheck cannot see tests/ so it flags every field as unused; each member is read in ra8_mipi_phy_init.
