From 201bf08ba9e26eeb0a96ba3fd5c026f531b31aed Mon Sep 17 00:00:00 2001 From: Taniya Das Date: Mon, 14 Apr 2025 14:30:41 +0530 Subject: [PATCH] clk: qcom: gcc-x1e80100: Set FORCE MEM CORE for UFS clocks Update the force mem core bit for UFS ICE clock and UFS PHY AXI clock to force the core on signal to remain active during halt state of the clk. If force mem core bit of the clock is not set, the memories of the subsystem will not retain the logic across power states. This is required for the MCQ feature of UFS.
