Pull DeviceTree updates from Rob Herring:
"Pretty standard stuff with dtc upstream sync being the biggest piece.

- Sync dtc to upstream commit 0931cea3ba20. This picks up overlay
support in dtc.

- Set dma_ops for reserved memory users.

- Make references to IOMMU consistent in DT bindings.

- Cleanup references to pm_power_off in bindings.

- Move some display bindings that snuck into the old bindings/video/
path.

- Fix some wrong documentation paths caused from binding
restructuring.

- Vendor prefixes for Faraday and Fujitsu.

- Fix an of_node ref counting leak in of_find_node_opts_by_path

- Introduce new graph helper of_graph_get_remote_node() which will be
used by DRM drivers in 4.12"

of: make of_device_make_bus_id() static

2017-02-09T15:29:37+00:00

of_device_make_bus_id() was changed to non-static by commit c66012253800
("of/device: Make of_device_make_bus_id() usable by other code") more than
6 years ago, but there are no users of it outside of platform.c.  Make the
function static again.

of: device: Support loading a module with OF based modalias

2017-01-20T03:23:51+00:00

In the case of ULPI devices, we want to be able to load the
driver before registering the device so that we don't get stuck
in a loop waiting for the phy module to appear and failing usb
controller probe. Currently we request the ulpi module via the
ulpi ids, but in the DT case we might need to request it with the
OF based modalias instead. Add a common function that allows
anyone to request a module with the OF based modalias.

of: constify drv arg of of_driver_match_device stub

2015-07-27T13:23:27+00:00

With this change the stub has the same signature as the actual function,
preventing this compiler warning when building without CONFIG_OF:

   drivers/base/property.c: In function 'fwnode_driver_match_device':
>> drivers/base/property.c:608:38: warning: passing argument 2 of 'of_driver_match_device' discards 'const' qualifier from pointer target type

of: add helper function to retrive match data

2015-05-28T17:59:40+00:00

It's a common operation for device drivers to retrive the data
member from of_device_id struct in their probe function.

Most driver end up doing:
    const struct of_device_id *match;
    match = of_match_device(driver_of_match, &pdev->dev);
    driver->data = match->data;

With the of_device_get_match_data helper function all this can
done in one go.

of: Move of_dma_configure() to device.c to help re-use

2015-03-03T20:42:56+00:00

Move of_dma_configure() to device.c so it can be re-used for PCI devices to
obtain DMA configuration from DT.  Also add a second argument so that for
PCI, the DT node of root bus host bridge can be used to obtain the DMA
configuration for the slave PCI device.

of/device: Nullify match table in of_match_device() for CONFIG_OF=n

2014-02-05T16:04:37+00:00

If the of_device_id table inside a device driver is protected by #ifdef
CONFIG_OF, the driver still has to provide a dummy declaration of the
table, or wrap it inside of_match_ptr(), when calling of_match_device()
in the CONFIG_OF=n case, else the driver fails to compile with e.g.

drivers/spi/spi-rspi.c: In function 'rspi_probe':
drivers/spi/spi-rspi.c:1203:26: error: 'rspi_of_match' undeclared (first use in this function)
drivers/spi/spi-rspi.c:1203:26: note: each undeclared identifier is reported only once for each function it appears in

Make of_match_device() nullify the table pointer if CONFIG_OF=n to fix
this.

of/device: add helper to get cpu device node from logical cpu index

2013-08-21T09:29:51+00:00

Multiple drivers need to get the cpu device node from the cpu logical
index and then access the of_node.

This patch adds helper function to fetch the device node directly.

of: remove CONFIG_OF_DEVICE

2013-06-12T11:37:40+00:00

CONFIG_OF_DEVICE is always selected when CONFIG_OF is enabled, so remove
it and simplify of_platform.h and of_device.h headers. This also fixes
!OF compiles using of_platform_populate.
