of: do not leak console options

2017-10-12T17:22:04+00:00

Do not strdup() console options. It seems that the only reason for it to be strdup()-ed was a compilation warning: printk, UART and console drivers, for some reason, expect char pointer instead of const char pointer. So we can just pass `of_stdout_options', but need to cast it to char pointer. A better fix would be to change printk, console drivers and UART to accept const char `options'; but that will take time - there are lots of drivers to update. The patch also fixes a possible memory leak: add_preferred_console() can fail, but we don't kfree() options. Signed-off-by: Sergey Senozhatsky Reviewed-by: Petr Mladek Signed-off-by: Rob Herring

of: base: use of_property_read_string()

2017-07-24T14:50:34+00:00

of_alias_scan() can use of_property_read_string() -- using the modern DT API adds some prop sanity checks as a bonus; it does add couple LoCs but only because the original code violated the 80-column limit... Signed-off-by: Sergei Shtylyov Signed-off-by: Rob Herring

of: base: use of_property_read_u32()

2017-07-24T14:50:07+00:00

of_n_{addr|size}_cells() predate of_property_read_u32(), so they have to basically open-code it. Using the modern DT API saves several LoCs and also adds some prop sanity checks as a bonus... Signed-off-by: Sergei Shtylyov 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

Merge branch 'dt/property-move' into dt/next

Merge branch 'topic/of-graph-base' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into dt/property-move

OF graph changes for ALSA conflict with the move of graph functions into property.c.

of: find_node_by_full_name rewrite to compare each level

2017-06-22T17:38:29+00:00

find_node_by_full_name() does the same thing as of_find_node_by_path(), but takes no locks and doesn't work on aliases. Refactor of_find_node_opts_by_path() into __of_find_node_by_full_path() and replace find_node_by_full_name() with it. 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

of: be consistent in form of file mode

2017-06-22T16:16:44+00:00

checkpatch whined about using S_IRUGO instead of octal equivalent when adding phandle sysfs code, so used octal in that pending patch. Change other instances of the S_* constants in the same file to the octal form. Signed-off-by: Frank Rowand Signed-off-by: Rob Herring

of: Move OF property and graph API from base.c to property.c

2017-06-01T13:50:45+00:00

base.c contains both core OF functions and increasingly other functionality such as accessing properties and graphs, including convenience functions. In the near future this would also include OF specific implementation of the fwnode property and graph APIs. Create driver/of/property.c to contain procedures for accessing and interpreting device tree properties. The procedures are moved from drivers/of/base.c, with no changes other than copying only the includes required by the moved procedures. Signed-off-by: Sakari Ailus Signed-off-by: Rob Herring
