Cover letter [PATCHv3 0/9] ARM: OMAP2+: AM33XX: Add suspend-resume support
Quoted 20 lines · Dave Gerlach

Hi,

This is the third version of the patch series for adding basic suspend-resume support for AM33XX, previously submitted by Vaibhav Bedia. This patchset is based on 3.11-rc4 and depends on a forthcoming patchset from Suman Anna that adds mailbox support for the wkup_m3. The patches at [1], [2], and [3] are required for the pm code to properly suspend and resume.

The PM code uses the firmware interface and expects the userspace to load the WKUP_M3 binary before the suspend-resume functionality is made available. The binary file (and the source-code for WKUP_M3) can be obtained from the 'next2' branch at [4]. The WKUP_M3 binary can either be loaded post bootup via the sysfs entry './sys/devices/ocp.2/wkup_m3.4/firmware' or it can be included in the kernel image as part of the build process.

Suspend to mem is tested on am335x-bone and am335x-evm.

More details on AM335x suspend-resume are provided within the commit logs for each patch.

Please CC people who have at least reviewed the last version of the series. Couple of patches I was CC'ed o.w I would missed this series.

Regards,
Santosh
