The second pin provides the SCIF_CLK signal for HSCIF2 and SCIF4. The first pin provides the SCIF_CLK signal for the other (H)SCIF instances. This patch series adds the missing SCIF_CLK2 pin group/function to the R-Car V4H pin control driver and to the R-Car V4H DTS file, and fixes the HSCIF2 and SCIF4 DT descriptions to refer to the proper clock. As SCIF_CLK2 cannot be used on the White Hawk development board, I could not test proper operation of HSCIF2 and SCIF4. I did verify that HSCIF2 and SCIF4 do not operate properly when trying to use (the first and thus incorrect) SCIF_CLK as the clock source. I plan to queue these in renesas-pinctrl resp. renesas-devel for v6.9. Thanks for your comments!
