* of: of_path: add of_find_node_by_devpath()Sascha Hauer2017-03-311-0/+107
| | | | | | | | | | | | | | | | | | | | | | | | | | We already have of_find_path_by_node() which finds a device path for a given device node. This is used by the state framework to find its backend path. This path has to be translated back to a device node when Linux is started. The current approach turned out to be too simple: We assumed that the node path is the same in the tree Linux is started with. This is not true in several cases: - partition nodes should have the name "partition@<offset>", but in several trees they have "partition@<num>" - There are two different partition bindings: The legacy binding and the new one with an additional partitions subnode which has a compatible = "fixed-partitions" property. The node path only stays the same when the internal tree uses the same bindings and node names as the tree Linux is started with. To overcome this limitation we create of_find_node_by_devpath() which converts the device path back to a device node. It does so by finding the device node of the hardware device rather than the partition node. It then parses over the partitions in this device node with the known bindings looking for a partition which matches in offset and size to the barebox partition.

* of: partition: Register the of partition fixup for of partition usersSascha Hauer2017-03-313-1/+6

* of: partitions: flag partitions from a partition tableSascha Hauer2017-03-311-2/+6
| | | | | | | | | We are going to call the of_partition_fixup for regular block devices like MMC/SD aswell. Add a flag to partitions indicating they are instanciated from a on-disk partition table so that they won't be added as device tree partitions during fixup.

* of: partition: only create partition node when partitions existSascha Hauer2017-03-311-1/+8
| | | | | | | | | With the legacy partition binding we did not modify the device node when no partition exist, but with the new binding we would create the "partitions" node with compatible = "fixed-partitions". Prevent that by catching the absence of partitions early. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* fs: devfs-core: replace DEVFS_IS_PARTITION flag with pointer to the master cdevSascha Hauer2017-03-312-1/+3
| | | | | | | | Instead of having a flag indicating a cdev is a partition on some master cdev, just add a master pointer to the cdev, so that we can also find out who the master is. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of: partition: Make partition fixup independent from mtd devicesSascha Hauer2017-03-311-18/+27

* mtd: of: Make used partition binding configurableSascha Hauer2017-03-301-7/+77
| | | | | | | | | | | | | | So far we used the legacy partition binding when fixing up the mtd partition nodes. Change this to default to the new binding with a "partitions" submode. Make this behaviour configurable though: This creates a new of_binding device variable for mtd devices. This can be set to: - "new": Use the new partition binding (default) - "legacy": Use the old partition binding - "donttouch": Do not touch the partition node Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

| * | usb: gadget: properly release f_multi_optsSascha Hauer2017-03-091-2/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The usbgadget commands uses statically allocated f_multi_opts and passes this to usb_multi_register(). These f_multi_opts are of course no longer valid when we leave the usbgadget command. Luckily we do not use the data after we left the usbgadget command, so this never has been a problem. However, f_multi_opts has some allocated members which we can not free anymore on gadget unregistration because we no longer have the pointer to them. Fix this by adding a release function to struct f_multi_opts. This way we can allocate all memory dynamically and properly free it when not used anymore.
