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
