ARM: AM43xx: Enable DDR dynamic IO power down for DDR3
This patch enables dynamically powering down the IO receiver when not performing a read on DDR3 board. This optimizes both active and standby power consumption. This is derived from a patch that is done on AM335x[1] [1] http://arago-project.org/git/projects/?p=u-boot-am33x.git;a=commit;h=6a9ee4bc72ece53fabf01825605fba3d71d5feb2 Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
