of: Transactional DT support.

2014-07-23T23:29:15Z

Introducing DT transactional support. A DT transaction is a method which allows one to apply changes in the live tree, in such a way that either the full set of changes take effect, or the state of the tree can be rolled-back to the state it was before it was attempted. An applied transaction can be rolled-back at any time.

of: Reorder device tree changes and notifiers

2014-07-23T23:08:13Z

Currently, devicetree reconfig notifiers get emitted before the change is applied to the tree, but that behaviour is problematic if the receiver wants the determine the new state of the tree. The current users don't care, but the changeset code to follow will be making multiple changes at once. Reorder notifiers to get emitted after the change has been applied to the tree so that callbacks see the new tree state. At the same time, fixup the existing callbacks to expect the new order. There are a few callbacks that compare the old and new values of a changed property. Put both property pointers into the of_prop_reconfig structure. The current notifiers also allow the notifier callback to fail and cancel the change to the tree, but that feature isn't actually used. It really isn't valid to ignore a tree modification provided by firmware anyway, so remove the ability to cancel a change to the tree. Signed-off-by: Grant Likely Cc: Nathan Fontenot

of: Make devicetree sysfs update functions consistent.

2014-07-23T23:05:06Z

All of the DT modification functions are split into two parts, the first part manipulates the DT data structure, and the second part updates sysfs, but the code isn't very consistent about how the second half is called. They don't all enforce the same rules about when it is valid to update sysfs, and there isn't any clarity on locking. The transactional DT modification feature that is coming also needs access to these functions so that it can perform all the structure changes together, and then all the sysfs updates as a second stage instead of doing each one at a time. Fix up the second have by creating a separate __of_*_sysfs() function for each of the helpers. The new functions have consistent naming (ie. of_node_add() becomes __of_attach_node_sysfs()) and all of them now defer if of_init hasn't been called yet. Callers of the new functions must hold the of_mutex to ensure there are no race conditions with of_init(). The mutex ensures that there will only ever be one writer to the tree at any given time. There can still be any number of readers and the raw_spin_lock is still used to make sure access to the data structure is still consistent. Finally, put the function prototypes into of_private.h so they are accessible to the transaction code.

of/platform: Fix of_platform_device_destroy iteration of devices

2014-07-07T12:33:46Z

of_platform_destroy does not work properly, since the tree population test was iterating on all devices having as its parent the given platform device. The check was intended to check whether any other platform or amba devices created by of_platform_populate were still populated, but instead checked for every kind of device. This is wrong, since platform devices typically create a subsystem regular device and set themselves as parents. Instead, go ahead and call the unregister functions for any devices created with of_platform_populate. The driver core will take care of unbinding drivers, and drivers are responsible for getting rid of any child devices that weren't created by of_platform_populate.

tty: Update hypervisor tty drivers to use core stdout parsing code.

2014-06-26T16:12:23Z

The evh_bytechan, hvc_opal and hvc_vio drivers all open code the parsing of the stdout node in the device tree. This patch simplifies the driver by removing the duplicated functionality. Signed-off-by: Grant Likely

of: Create of_console_check() for selecting a console specified in /chosen

2014-06-26T16:12:22Z

The devicetree has a binding for specifying the console device in the /chosen node, but the kernel doesn't use it consistently. This change adds an API for testing if a device node is a console, and adds a preferred console entry if it is. At the same time this patch removes the of_device_is_stdout_path() API since it is unused. Signed-off-by: Grant Likely Tested-by: Sascha Hauer

of: consolidate linker section OF match table declarations

2014-05-20T19:25:24Z

We now have several OF match tables using linker sections that are nearly the same definition. The only variation is the callback function prototype. Create a common define for creating linker section OF match table entries which each table declaration can use. Acked-by: Grant Likely Signed-off-by: Rob Herring
