PM / OPP: Remove useless check

2016-05-04T23:42:19Z

Regulators are optional for devices using OPPs and the OPP core shouldn't be printing any errors for such missing regulators. It was fine before the commit 0c717d0f9cb4, but that failed to update this part of the code to remove an 'always true' check and an extra unwanted print message. Fix that now.

PM / wakeirq: fix wakeirq setting after wakup re-configuration from sysfs

2016-04-07T20:23:47Z

Now wakeirq stops working for device if wakeup option for this device will be reconfigured through sysfs, like: echo disabled > /sys/devices/platform/extcon_usb1/power/wakeup echo enabled > /sys/devices/platform/extcon_usb1/power/wakeup Once above set of commands is executed the device's wakeup_source opject will be recreated and dev->power.wakeup->wakeirq field will contain NULL. As result, device_wakeup_arm_wake_irqs() will not arm wakeirq for the affected device. Hece, lets try to fix it in the following way: check for dev->wakeirq field when device_wakeup_attach() is called and if !NULL re-attach wakeirq to the device Signed-off-by: Grygorii Strashko Acked-by: Tony Lindgren Signed-off-by: Rafael J.

PM / clk: Add support for obtaining clocks from device-tree

2016-03-17T01:32:04Z

The PM clocks framework requires clients to pass either a con-id or a valid clk pointer in order to add a clock to a device. Add a new function of_pm_clk_add_clks() to allows device clocks to be retrieved from device-tree and populated for a given device. Note that it is not necessary to make the compilation of this new function dependent upon CONFIG_OF because there are stubs functions for the device-tree APIs used. In order to handle errors encountered when adding clocks from device-tree, add a function pm_clk_remove_clk() to remove any clocks (using a pointer to the clk structure) that have been added successfully before the error occurred.

PM / Domains: Fix potential NULL pointer dereference

2016-03-08T23:41:07Z

In the function of_genpd_get_from_provider(), we never check to see if the argument 'genpdspec' is NULL before dereferencing it. Add error checking to handle any NULL pointers. Signed-off-by: Jon Hunter Acked-by: Ulf Hansson Signed-off-by: Rafael J. Wysocki

PM / Domains: Fix removal of a subdomain

2016-03-08T23:41:06Z

Commit 30e7a65b3fdb (PM / Domains: Ensure subdomain is not in use before removing) added a test to ensure that a subdomain is not a master to another subdomain or if any devices are using the subdomain before removing. This change incorrectly used the "slave_links" list to determine if the subdomain is a master to another subdomain, where it should have been using the "master_links" list instead. The "slave_links" list will never be empty for a subdomain and so a subdomain can never be removed. Fix this by testing if the "master_links" list is empty instead.

PM / Domains: Propagate start and restore errors during runtime resume

2016-03-08T23:37:59Z

During runtime resume the return values of the start and restore steps are ignored. As a result drivers are not notified of runtime resume failures and can't propagate them up. Fix it by returning an error if either the start or restore step fails, and clean up properly in the error path.

PM / Domains: Join state name and index in debugfs output

2016-03-08T23:36:03Z

For low-power states, the state index is part of the state, hence join them with a hyphen in the /sys/kernel/debug/pm_genpd/pm_genpd_summary output. E.g. "off 0" becomes "off-0". Signed-off-by: Geert Uytterhoeven Acked-by: Ulf Hansson Tested-by: Kevin Hilman Signed-off-by: Rafael J. Wysocki

PM / Domains: Restore alignment of slaves in debugfs output

2016-03-08T23:36:03Z

The slave domains are no longer aligned with the table header in the /sys/kernel/debug/pm_genpd/pm_genpd_summary output. Worse, the alignment differs depending on the actual name of the state. Format the state name and index into a buffer, and print that like before to restore alignment. Use "%u" for unsigned int while we're at it.
