If so it would be good to > understand the dependency. May be we are missing a clock somewhere? Sorry. I forgot to mention that the TEGRA210_CLK_APE_SLCG_OVR clock is required for the tests. So I cherry-picked 2 patches from your audio branch to the linux-next: clk: tegra210: Add SLCG override gate clocks ARM64: tegra: DT: Add SLCG clock for AUD Besides these two, there'e merely some straightforward changes to enable the ADMA in the defconfig and DT. And it seems that you've submitted that patch once but it got hold because it wasn't so useful at that time? Thanks Nic
