mtd: partitions: support a cleanup callback for parsers

2015-12-09T22:57:44+00:00

If partition parsers need to clean up their resources, we shouldn't
assume that all memory will fit in a single kmalloc() that the caller
can kfree(). We should allow the parser to provide a proper cleanup
routine.

Note that this means we need to keep a hold on the parser's module for a
bit longer, and release it later with mtd_part_parser_put().

Alongside this, define a default callback that we'll automatically use
if the parser doesn't provide one, so we can still retain the old
behavior.

mtd: partitions: pass around 'mtd_partitions' wrapper struct

2015-12-09T18:22:09+00:00

For some of the core partitioning code, it helps to keep info about the
parsed partition (and who parsed them) together in one place.

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.

mtd: partitions: add module_mtd_part_parser() helper

2015-11-20T02:46:28+00:00

This can help eliminate some boilerplate by generating the module_init()
and module_exit() functions, and by automatically assigning the module
owner.

mtd: ofpart: grab device tree node directly from master device node

2015-11-11T21:45:10+00:00

It seems more logical to use a device node directly associated with the
MTD master device (i.e., mtd->dev.of_node field) rather than requiring
auxiliary partition parser information to be passed in by the driver in
a separate struct.

This patch supports the mtd->dev.of_node field and deprecates the parser
data 'of_node' field

Driver conversions may now follow.

Additional side benefit to assigning mtd->dev.of_node rather than using
parser data: the driver core will automatically create a device -> node
symlink for us.
