From c5c95dbdc9011a56359df4dc00be829bbcc0b036 Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Fri, 21 Aug 2026 14:01:24 +0100 Subject: [PATCH] soc/tegra: pmc: Fix uninitialised clock rate For legacy 32-bit Tegra devices, the warning in the tegra_pmc_enter_suspend_mode() function is being triggered because the early_pmc->rate variable is never configured and hence, always 0. This issue started occurring after updating the PMC driver to create the PMC context dynamically which causes the 'rate' to be set in the new dynamic context, but missed updating the rate in the early PMC context. Fix this by initialising the early_pmc->rate variable for 32-bit Tegra devices when the rate for the PMC context is initialised.
