[PATCH 03/11] pinctrl: sh-pfc: r8a7791: Add SCIF_CLK support


Biju Das <biju.das@...>
 

From: Geert Uytterhoeven <geert+renesas@...>

Add pins, groups, and a function for SCIF_CLK, which is the external
clock source for the Baud Rate Generator for External Clock (BRG) on
(H)SCIF.

Signed-off-by: Geert Uytterhoeven <geert+renesas@...>
Acked-by: Linus Walleij <linus.walleij@...>
(cherry picked from commit a4c8a6d2f6ed3686ce0cc789ed9213f579ebd4ad)
