Hi
Here is V4 of some patches to move re-tuning support
out of sdhci and into the core, and add support for HS400
re-tuning.
Currently sdhci does re-tuning transparently by
calling sdhci_execute_tuning() from its -request()
function.

Okay, so to me, I think the SLEEP notification needs to be sent as a part of
the
system PM suspend phase. And more exactly from the
bus_ops-suspend() callback.
PM suspend phase is a right place for PON Sleep_Notification,
but it also the critical one and need to be completed as

The eMMC on the A13 based Utoo-P66 tablet does not properly support hpi,
and trying to enable it results in the eMMC not working, so add a child-node
describing the eMMC, and set the broken-hpi property on it.

Ad hoc testing with Lenovo Thinkpad 10 showed a stress
test could run for at least 24 hours with the patches,
compared to less than an hour without.
There is a patch in linux-next to delete C1E from BYT,
since it is problematic on multiple platforms.
