47 * The below are numbered starting from "S1" on gen11/gen12, but starting
48 * with display 13, the bspec switches to a 0-based numbering scheme
49 * (although the addresses stay the same so new S0 = old S1, new S1 = old S2).
50 * We'll just use the 0-based numbering here for all platforms since it's the
51 * way things will be named by the hardware team going forward, plus it's more
52 * consistent with how most of the rest of our registers are named.
