From f07e58b878fc18bd69d2c19075f0fb8d7d35da00 Mon Sep 17 00:00:00 2001 From: Simon Glass Date: Sun, 26 Jan 2020 22:06:27 -0700 Subject: cpu: Convert the methods to use a const udevice * These functions should not modify the device. Convert them to const so that callers don't need to cast if they have a const udevice *.
