From: Fabrizio Castro fabrizio.castro@bp.renesas.com
[ Upstream commit 57eec02caee60332b8052615e7257f932ae07abc ]
This patch adds can_clk function to r8a7743/r8a7791 which is cleaner, and allows for independent configuration. We keep the can_clk* pins definitions from within can0_groups and can1_groups for uniformity and backwards compatibility.
