[PATCH 0/5] mtd: migrate 'of_node' handling to core, not in mtd_part_parser_data

From: Brian Norris

Hi,

I noticed that, for MTD drivers that want to support DT partition parsing
(essentially all recent ones), it's a bit awkward to set the tell MTD which DT
node to use. I also noticed that this info is duplicated in a few places;
namely, some sub-subsystems (like SPI NOR and NAND) need their own field to
track the DT node, so let's have the propagate the 'MTD' DT node down for us.

Besides simplifying the boilerplate throughout MTD, this series also has the
side effect of producing 'of_node' symlinks in sysfs. e.g.:

# ls -al /sys/class/mtd/mtd0/of_node
lrwxrwxrwx 1 root root 0 Oct 26 19:17 /sys/class/mtd/mtd0/of_node -> ../../../../firmware/devicetree/base/spi@ff130000/flash@0

For NAND, this potentially has some other bigger initial side effects, since
nand_dt_init() handles a bit more automagically for drivers that defined their
->flash_node. But these drivers should probably convert anyway. So, please test
your favorite driver!

Thanks,
Brian
