From: Lad Prabhakar <prabhakar.mahadev-lad.rj@xxxxxxxxxxxxxx> Document support for the Serial Communication Interface with FIFO (SCIF) available in the Renesas RZ/V2H(P) (R9A09G057) SoC. The SCIF interface in the Renesas RZ/V2H(P) is similar to that available in the RZ/G2L (R9A07G044) SoC, with the only difference being that the RZ/V2H(P) SoC has three additional interrupts: one for Tx end/Rx ready and the other two for Rx and Tx buffer full, which are edge-triggered. No driver changes are required as generic compatible string "renesas,scif-r9a07g044" will be used as a fallback on RZ/V2H(P) SoC.
