From dc6d5d85ed3a3fe566314f388bce4c71a26b1677 Mon Sep 17 00:00:00 2001 From: Sameer Pujar spujar@nvidia.com Date: Thu, 29 Jun 2023 10:42:17 +0530 Subject: [PATCH] arm64: tegra: Update AHUB clock parent and rate
I2S data sanity test failures are seen at lower AHUB clock rates on Tegra234. The Tegra194 uses the same clock relationship for AHUB and it is likely that similar issues would be seen. Thus update the AHUB clock parent and rates here as well for Tegra194, Tegra186 and Tegra210.
