* Convert users of PRINTF_CONVERSION_RESOURCE to %paSascha Hauer2016-01-151-2/+5
| | | | | | | | printf now supports printing resource_size_t directly, convert all users of the previously used PRINTF_CONVERSION_RESOURCE over to %pa. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>
* of_path: Drop possible further extensions of device-path propertySascha Hauer2016-01-081-95/+28
| | | | | | | | | | Originally it was intended to further extend the multi string property device-path further with more elements, like for example a filename. It turned out though that this is too complex and instead of further extending the property we should instead create additional properties, so this mechanism is removed with this patch to make the code simpler.

* environment: Support env from file in a file-system via device treeTrent Piepho2016-01-082-2/+52
| | | | | | | | | | | | | | | Current barebox,environment node only allows specifying a raw device or partition to load an environment from. Some boards, like OMAP and SoCFPGA, instead want to use a file located in a FAT filesystem. Extend the device tree bindings with a new property 'file-path' that will trigger this behavior. This allows any board using this driver to get the env from a file or from a raw device, instead of each machine type being either raw device only or file only.

* of_path: Fix bug with partitions, simply codeTrent Piepho2016-01-081-18/+29
| | | | | | | | | | | | | | | | | | | | | | In commit 75b682795eafb2385556a9642f09e0af96a1264a using a path that has a partition description broke. Fix this and simpfy the code some. There is no need to loop over each string in the path property: it's defined to have at most one parition description, no extant dts has more than one, and how it would handle more than one didn't make sense anyway. Once not looping, __of_find_path() just needs the partition description text, not both the original node and property name to look it up from. When using a partition description, don't lookup the cdev of the node just to replace it with the partition's cdev.

| * of_path: add of_find_path_by_node()Marc Kleine-Budde2015-11-271-1/+16
| | | | | | | | | | | | | | | | | | This patch adds the function of_find_path_by_node(), which is similar to of_find_path(), but it translates a device tree node into a barebox device path directly.

* cdev: Add function to find cdev by device_nodeSascha Hauer2015-09-011-2/+2
| | | | | | | | | | This adds a device_node member to struct cdev and a function to find a cdev by device_node. This also removes the setting of cdev->dev->device_node in the of partition parser. We must not set the device since it may not refer to a partition but to a whole device with partitions. Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de>

A QSMII interface, as defined at http://en.wikipedia.org/wiki/Media_Independent_Interface#Quad_Serial_Gigabit_Media_Independent_Interface, is "is a method of combining four SGMII lines into a 5Gbit/s interface. QSGMII, like SGMII, uses LVDS signalling for the TX and RX data and a single LVDS clock signal. QSGMII uses significantly fewer signal lines than four SGMII busses." This type of MAC <-> PHY connection might require special handling on the MAC driver side, so it should be possible to express this type of MAC <-> PHY connection, for example in the Device Tree.
