Patch "pinctrl: sh-pfc: r8a7791: Add can_clk function" has been added to the 4.15-stable tree

by gregkh＠linuxfoundation.org

This is a note to let you know that I've just added the patch titled pinctrl: sh-pfc: r8a7791: Add can_clk function to the 4.15-stable tree which can be found at: http://www.kernel.org/git/?p=linux/kernel/git/stable/stable-queue.git;a=sum… The filename of the patch is: pinctrl-sh-pfc-r8a7791-add-can_clk-function.patch and it can be found in the queue-4.15 subdirectory. If you, or anyone else, feels it should not be added to the stable tree, please let <stable(a)vger.kernel.org> know about it. >From foo@baz Fri Mar 16 15:11:07 CET 2018 From: Fabrizio Castro <fabrizio.castro(a)bp.renesas.com> Date: Tue, 14 Nov 2017 15:41:17 +0000 Subject: pinctrl: sh-pfc: r8a7791: Add can_clk function From: Fabrizio Castro <fabrizio.castro(a)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.
