Subject: [PATCH 0/8] Improve PM for omap4 devices
Date: Wed, 9 Oct 2019 17:12:16 -0700 [thread overview]
Message-ID: <20191010001224.41826-1-tony@atomide.com> (raw)
Hi all,
We've had core oswr (open switch retention) disabled for a while now for
omap4 devices because of all kind of GPIO issues it caused with bootloaders
that configured per and core LOGICRETSTATE bits.
With all the recent GPIO fixes, these issues are now gone, and we can enable
per and core oswr again.
By adding the voltage controller data for droid4, we can get it idle at
something like 40 to 50 mW for the whole device with LCD blanked, and USB and
modem shut down.
Regards,
Tony
