Subject: pinctrl: sh-pfc: r8a7795: Add SCIF_CLK support
X-Git-Url: http://git.efficios.com/?a=commitdiff_plain;h=f27200f9dce59ce5063bf722ef6ccedd34e4357b;p=deliverable%2Flinux.git

pinctrl: sh-pfc: r8a7795: Add SCIF_CLK support

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.
