From 2e48345a3b201555ab7c222cf5e847ae6d4e7627 Mon Sep 17 00:00:00 2001 From: Vivek Aknurwar Date: Wed, 25 Mar 2020 17:29:59 -0700 Subject: [PATCH] clk: qcom: gcc-lahaina: Keep ice core memory retained across gdsc collapse Enable FORCE_MEM_CORE_ON for ice core clock to retain keys in memory even on gdsc collpase. This will reduce performanace hit as client does not need to load/map keys in/out of UFS LPM state.
