mtd: Convert to using %pOF instead of full_name

2017-08-15T12:00:43+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.

drivers/mtd: Convert remaining uses of pr_warning to pr_warn

2017-04-19T20:10:54+00:00

To enable eventual removal of pr_warning This makes pr_warn use consistent for drivers/mtd Prior to this patch, there were 7 uses of pr_warning and 31 uses of pr_warn in drivers/mtd Signed-off-by: Joe Perches Signed-off-by: Brian Norris

mtd: Add partition device node to mtd partition devices

The user visible change here is that mtd partitions get an of_node link in sysfs. Signed-off-by: Sascha Hauer Signed-off-by: Uwe Kleine-König Signed-off-by: Brian Norris

mtd: partitions: make parsers return 'const' partition arrays

2015-12-09T18:21:57+00:00

We only want to modify these arrays inside the parser "drivers", so the drivers should construct them however they like, then return them as immutable arrays. This will make other refactorings easier. Signed-off-by: Brian Norris Reviewed-by: Boris Brezillon

mtd: ofpart: assign return argument exactly once

2015-12-09T18:21:52+00:00

It's easier to refactor these parsers if the return value gets assigned only once, just like every other MTD partition parser. This prepares for making the second arg to the parse_fn() const. This is OK if we construct the partitions completely first, and assign them to the return pointer only after we're done modifying them. Signed-off-by: Brian Norris Reviewed-by: Boris Brezillon

doc: dt: mtd: partitions: add compatible property to "partitions" node

2015-12-09T01:10:20+00:00

As noted here [1], there are potentially future conflicts if we try to use MTD's "partitions" subnode to describe anything besides just the fixed-in-the-device-tree partitions currently described in this document. Particularly, there was a proposal to use this node for the AFS parser too. It can pose a (small) problem to try to differentiate the following nodes: // using binding as currently specified partitions { #address-cells = ; #size-cells = ; partition@0 { ...; }; }; and // proposed future binding partitions { compatible = "arm,arm-flash-structure"; }; It's especially difficult if other uses of this node start having subnodes. So, since the "partitions" node is new in v4.4, let's fixup the binding before release so that it requires a compatible property, so it's much clearer to distinguish. e.g.: // proposed partitions { compatible = "fixed-partitions"; #address-cells = ; #size-cells = ; partition@0 { ...; }; }; [1] Subject: "mtd: create a partition type device tree binding" http://lkml.kernel.org/g/20151113220039.GA74382@google.com http://lists.infradead.org/pipermail/linux-mtd/2015-November/063355.html http://lists.infradead.org/pipermail/linux-mtd/2015-November/063364.html Cc: Michal Suchanek Signed-off-by: Brian Norris Acked-by: Rob Herring

mtd: ofpart: don't complain about missing 'partitions' node too loudly

2015-12-04T01:50:36+00:00

The ofpart partition parser might be run on DT-enabled systems that don't have any "ofpart" partition subnodes at all, since "ofpart" is in the default parser list. So don't complain loudly on every boot. Example: using m25p80.c with no intent to use ofpart: &spi2 { status = "okay"; flash@0 { compatible = "jedec,spi-nor"; reg = <0>; }; }; I see this warning: [ 0.588471] m25p80 spi2.0: gd25q32 (4096 Kbytes) [ 0.593091] spi2.0: 'partitions' subnode not found on /spi@ff130000/flash@0.

mtd: kill off MTD partition parser boilerplate

2015-11-20T02:46:29+00:00

Most parsers can be handled with our new boilerplate-reducing macro. There are a few that can't be (cmdlineparts and ofpart). Also kill off the owner assignments, since register_mtd_parser() now takes care of that. Signed-off-by: Brian Norris
