We need to call of_node_put() for device nodes obtained with of_find_node_by_path().

of: platform: populate /firmware/ node from of_platform_default_populate_init()

2018-01-04T20:00:20+00:00

Since "/firmware" does not have its own "compatible" property as it's just collection of nodes representing firmware interface, it's sub-nodes are not populated during system initialization. Currently different firmware drivers search the /firmware/ node and populate the sub-node devices selectively. Instead we can populate the /firmware/ node during init to avoid more drivers continuing to populate the devices selectively. To generalize the solution this patch populates the /firmware/ node explicitly from of_platform_default_populate_init().

soc: qcom: Remote filesystem memory driver

2017-10-22T10:06:34+00:00

The Qualcomm remote file system protocol is used by certain remoteprocs, in particular the modem, to read and write persistent storage in platforms where only the application CPU has physical storage access. The protocol is based on a set of QMI-encoded control-messages and a shared memory buffer for exchaning the data. This driver implements the latter, providing the user space service access to the carved out chunk of memory. Acked-by: Rob Herring Signed-off-by: Bjorn Andersson Signed-off-by: Andy Gross

of/platform: Generalize /reserved-memory handling

2017-10-22T10:06:33+00:00

By iterating over all /reserved-memory child nodes and match each one to a list of compatibles that we want to treat specially, we can easily extend the list of compatibles to handle - without having to resort to of_platform_populate() that would create unnecessary platform_devices.

of: Use PLATFORM_DEVID_NONE definition

2017-08-25T15:50:31+00:00

Use dedicated definition instead of plain -1 where it's appropriate. No functional change intended. Signed-off-by: Andy Shevchenko Signed-off-by: Rob Herring

of: Convert to using %pOF instead of full_name

2017-07-18T22:09:18+00:00

Now that we have a custom printf format specifier, convert users of full_name to use %pOF instead. This is preparation to remove storing of the full path string for each node. Signed-off-by: Rob Herring

of: use kbasename instead of open coding

2017-06-22T17:37:46+00:00

Several places in DT code open code the equivalent of kbasename. Replace them. The behavior for root nodes in node_name_cmp will be slightly different. Instead of comparing "/", "" will be compared. The comparison will be the same. Reviewed-by: Andy Shevchenko Signed-off-by: Rob Herring
