From dffd66f3379a76274238caa89b085eb0436732b1 Mon Sep 17 00:00:00 2001 From: Konrad Dybcio Date: Wed, 8 Feb 2023 10:13:31 +0100 Subject: clk: qcom: branch: Add helper functions for setting retain bits Most Qualcomm branch clocks come with a pretty usual set of bits that can enable memory retention by means of not turning off parts of the memory logic. Add them to the common header file and introduce helper functions for setting them instead of using magic writes.
