+To: <stable@vger.kernel.org>
+Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org>, Sasha Levin <sashal@kernel.org>, Aaron Kling <webgeek1234@gmail.com>, <linux-tegra@vger.kernel.org>, Jon Hunter <jonathanh@nvidia.com>

+From: Jon Hunter <jonathanh@nvidia.com>
+
+This reverts commit d95fdee2253e612216e72f29c65b92ec42d254eb which is
+upstream commit be4ae8c19492cd6d5de61ccb34ffb3f5ede5eec8.
+
+This commit is causing a suspend regression on Tegra186 Jetson TX2 with
+Linux v6.12.y kernels. This is not seen with Linux v6.15 that includes
+this change but indicates that there are there changes missing.
+Therefore, revert this change.
+
+Fixes: d95fdee2253e ("cpufreq: tegra186: Share policy per cluster")
