X-Git-Tag: v2.6.36-rc1~488^2~7^2~1 X-Git-Url: http://git.openpandora.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=564889c1c02698d66db76764ee4e0a5e86903971;p=pandora-kernel.git OMAP: PM constraints: add return values; add requesting device param to omap_pm_set_max_dev_wakeup_lat() Add return values to the PM constraint functions. This allows the PM core to provide feedback to the caller if a constraint is not possible. Update the one upstream user of omap_pm_set_max_mpu_wakeup_lat() to add a compatibility wrapper, needed until the driver is changed. Update some of the documentation to conform more closely to kerneldoc style. Add an additional device parameter to omap_pm_set_max_dev_wakeup_lat() to identify the device requesting the constraint. This is so repeated calls to omap_pm_set_max_dev_wakeup_lat() with the same requesting device can override the device's previously-set constraint. Also, it allows the PM core to make a decision as to whether or not the constraint should be satisfied, based on the caller's identity. Signed-off-by: Paul Walmsley --- Reading git-diff-tree failed
