* state: backend: support phandle and of_path referencesMarc Kleine-Budde2015-05-151-14/+58
| | | | | | | | | | | This patch improves the backend property, it can be either a phandle or a of_path. During probe() of the state driver the backend property is dereferenced and the resulting of_path is saved in the state context. In a later patch it will be used to generate a phandle reference to the backend during DT fixup.

* of_path: of_find_path(): add possibility to return .bb deviceMarc Kleine-Budde2015-04-231-1/+1
| | | | | | | | | This patch adds a flags argument to the of_find_path() function. The only flag defined for now is OF_FIND_PATH_FLAGS_BB. When used on NAND devices, the function returns the bad block aware device (the ".bb" device).

* state: add framework for persistent state handlingSascha Hauer2015-03-123-0/+86
| | | | | | | | | | | | | | | | This patch adds a framework to describe, access, store and restore a set of variables. A state variable set can be fully described in a devicetree node. This node could be part of the regular devicetree blob or it could be an extra devicetree solely for the state. The state variable set contains variables of different types and a place to store the variable set.

* driver: Attach info callback to device, not to driverSascha Hauer2013-05-301-20/+20
| | | | | | | | Since the info is device specific and not driver specific, attach the callback to the device. This makes it possible to have a info callback for a device which does not have a driver attached. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
