From 3091181beeefc37dd44b1a0f95015f4367b26a54 Mon Sep 17 00:00:00 2001 From: Nitin Rawat Date: Tue, 5 Sep 2023 10:53:59 +0530 Subject: [PATCH] scsi: ufs: qcom: Align programing of unipro clk attributes Currently CORE_CLK_1US_CYCLES, PA_VS_CORE_CLK_40NS_CYCLES are configured in clk scaling post change ops. This is not aligning to HPG. Move this to clk scaling pre change ops to align completely with hardware specification.
