Subject: [PATCH] clk: renesas: div6: Document fields used for parent selection
Git-commit: 2ebedd8d5ca8747fc7efd8a97129802bc6965468
Patch-mainline: v4.14-rc1
References: bsc#1051510

Add the missing documentation for the fields in struct div6_clock
related to parent selection for DIV6 clocks with selectable parents, as
found in R/SH-Mobile SoCs.

Fixes: c6d67fb037f4eaaf ("clk: shmobile: div6: support selectable-input clocks")
