From c36e6ec904876de1935b1d74d2d711e6f5ceb572 Mon Sep 17 00:00:00 2001 From: Dave Gerlach Date: Wed, 18 May 2016 18:36:28 -0500 Subject: [PATCH] ARM: dts: am335x-boneblack: Enable 1GHz OPP for cpu Although all PG2.0 silicon may not support 1GHz OPP for the MPU, older Beaglebone Blacks may have PG2.0 silicon populated and these particular parts are guaranteed to support the OPP, so enable it for PG2.0 on am335x-boneblack only.
