From ac2527bfc21739b77d687df1bfc4e973103fef7b Mon Sep 17 00:00:00 2001 From: Joseph Lo Date: Wed, 3 Jul 2013 17:50:38 +0800 Subject: ARM: tegra: add a flag for tegra_disable_clean_inv_dcache to do LoUIS or ALL Adding a flag for tegra_disable_clean_inv_dcache to flush cache as LoUIS or ALL. After this patch, the v7_flush_dcache_louis is used for CPU hotplug and CPU suspend in CPU power down (e.g. CPU idle power-down mode) case. And the v7_flush_dcache_all is used for CPU cluster power down (e.g. suspend to LP2 mode).
