This reverts commit 7b642273438cf500d36cffde145b9739fa525c1d which is commit 1dc3459009c33e335f0d62b84dd39a6bbd7fd5d2 upstream.
This patch broke RB5 (Qualcomm SM8250) devboard. The device reboots into USB crash dump mode after following error:
qcom_q6v5_pas 17300000.remoteproc: fatal error received: \ ABT_dal.c:278:ABTimeout: AHB Bus hang is detected, \ Number of bus hang detected := 2 , addr0 = 0x3370000 , addr1 = 0x0!!!Signed-off-by: Amit Pundir amit.pundir@linaro.org

Is this also reverted in Linus's tree? If not, why not?
I couldn't reproduce this crash on Linus's tree. It was first reported on android14-6.1 and then I could reproduce it on v6.1.19 as well, hence this revert.
A quick search points out that this patch is a part of a 8 patch series https://lore.kernel.org/lkml/20230209122806.18923-1-srinivas.kandagatla@lina... while only 5 of them landed on v6.1.y. May be we need the remaining fixes on v6.1.y as well? I can give the remaining patches a quick shot tomorrow if that helps.
Yes please, we would much rather take whatever is in Linus's tree than a special revert as that will keep the trees in sync better. If you can provide the missing git ids, I can just queue them up if you have tested them.
Cherry-picking the rest of the relevant fixes from the https://lore.kernel.org/lkml/20230209122806.18923-1-srinivas.kandagatla@lina... series didn't help.
Srini, does this patch series has a dependency on other upstream fixes as well? With the above patch series on v6.1.y, I see the following crash on RB5:
