Subject: Re: [PATCH v2 2/5] arm64: dts: r8a7795: Add cpuidle support for CA53 cores

Hello Geert, hello Lorenzo,

Many thanks for your comments and for the willingness to help.

For your information, we've recently discovered that, with all the
findings already described being absolutely valid for the reference
targets, disabling CPUidle on the customer HW is apparently not enough
to fix the audio dropouts. We will first try to identify those
differences (both HW and SW) which keep the issue reproducible on the
customer boards. Once this is hopefully understood, we'll come back
with feedback.

This investigation also happens to overlap with my vacation. Hence I
plan to update you on this topic in 2-4 weeks from now.

Thanks again.

Best regards,
Eugeniu.
