From b7c4114b07bbacfe0aee1d04ad1ade9e42309620 Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 10 Jun 2013 23:12:57 -0300 Subject: can: flexcan: Use a regulator to control the CAN transceiver Instead of using a GPIO to turn on/off the CAN transceiver, it is better to use a regulator as some systems may use a PMIC to power the CAN transceiver.
