Subject: [PATCH] clk: renesas: r8a7745: Remove PLL configs for MD19=0
Git-commit: 5ed793b3b29c064f0b84c19a94d4e17831cc1dc2
Patch-mainline: v4.13-rc1
References: bsc#1051510
According to tables 7.5b and 7.6b of the RZ/G Series Hardware User's
Manual Rev.1.00, MD19=0 is a prohibited setting.
Hence stop looking at MD19, and remove all PLL configurations for
MD19=0.
