From 0e1c7a94c6def25fa2458ad4577b0b9b40443c3b Mon Sep 17 00:00:00 2001 From: Ramesh Shanmugasundaram Date: Fri, 10 Nov 2017 13:58:50 +0000 Subject: [PATCH] pinctrl: sh-pfc: r8a7795: Add CAN FD support This patch adds CAN FD[0-1] pinmux support for R-Car H3 ES2.0. The pin config is identical to H3 ES1.*.
