Thank you for your contribution! Sashiko AI review found 1 potential issue(s) to consider:
- [Low] Unused macros `RK3328_SPREAD_SPECTRUM_MOD_DOWN` and `RK3328_SPREAD_SPECTRUM_MOD_DISABLE` were left behind despite the commit message claiming that unused pre-PLL macros were removed.

phy: rockchip: inno-hdmi: Use the common Innosilicon PHY helpers

This commit refactors the RK3328 pre-PLL programming to use shared
Innosilicon PHY helpers. It removes local copies of register-level code,
macros, and table lookups. The RK3228 retains its own register code while
sharing the table lookup.

[Severity: Low]
Are these macros still needed? The commit message states that unused pre-PLL
macros are being removed, but these appear to have been left behind. Since
the shared helper uses its own definitions, are these now orphaned dead code?
