From 9173c5ceb035aab28171cd74dfddf27f47213b99 Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Thu, 21 Mar 2019 19:14:38 -0400 Subject: PM / devfreq: rk3399_dmc: Pass ODT and auto power down parameters to TF-A. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Trusted Firmware-A (TF-A) for rk3399 implements a SiP call to get the on-die termination (ODT) and auto power down parameters from kernel, this patch adds the functionality to do this. Also, if DDR clock frequency is lower than the on-die termination (ODT) disable frequency this driver should disable the DDR ODT.
