From d6e7bbc148f9fbec8a0117b0d0f420c9710e6d81 Mon Sep 17 00:00:00 2001 From: Russ Dill Date: Tue, 4 Sep 2018 12:19:37 +0530 Subject: clk: ti: Add functions to save/restore clk context SoCs like AM43XX lose clock registers context during RTC-only suspend. Hence add functions to save/restore the clock registers context.
