    Subject[PATCH 17/25] serial: sh-sci: Correct SCIF type on R-Car for BRG
    Date
    The "renesas,scif" compatible value is currently used for the SCIF
    variant in all Renesas SoCs of the R-Car family. However, the variant
    used in the R-Car family is not the common "SH-4(A)" variant, but a
    derivative with added "Baud Rate Generator for External Clock" (BRG),
    which is also present in sh7734.

    Use the (already documented) SoC-specific SCIF compatible values for all
    supported R-Car Gen1, Gen2, and Gen3 SoCs to differentiate. The
    "renesas,scif" compatible value can still be used as a common
    denominator for SCIF variants with the "SH-4(A)" register layout (i.e.
    ignoring the "Serial Extension Mode Register" (SCEMR) and the new
    BRG-specific registers).
