From 61f66fd5a81b97478e9d14326c1059baa6626680 Mon Sep 17 00:00:00 2001 From: Vitaly Andrianov Date: Fri, 25 Jul 2014 22:23:19 +0300 Subject: keystone2: use EFUSE_BOOTROM information to configure PLLs This patch reads EFUSE_BOOTROM register to see the maximum supported clock for CORE and TETRIS PLLs and configure them accordingly.
