Subject: [PATCH 0/3] OMAP: Add DT bindings to specify when devices should not be idled or reset
Date: Tue, 20 Aug 2013 13:02:43 +0530 [thread overview]
Message-ID: <1376983966-16490-1-git-send-email-rnayak@ti.com> (raw)
We have devices like co-processors, SoC internal busses, memory controllers
etc which should not be idled or reset. In some cases erratas around IP blocks
prevent them from either being idled or reset. Have a way to pass this
information from Device tree, and get rid of similar information that
exists as part of the omap_hwmod data files for various DT only OMAP SoCs.
Patches are tested on am335x beagleboneblack and omap4 panda es boards.
