Pull MTD updates from Brian Norris:
"Generic MTD:
- populate the MTD device 'of_node' field (and get a proper 'of_node'
symlink in sysfs)
This yielded some new helper functions, and changes across a
variety of drivers
- partitioning cleanups, to prepare for better device-tree based
partitioning in the future
Eliminate a lot of boilerplate for drivers that want to use
OF-based partition parsing
The DT bindings for this didn't settle yet, so most non-cleanup
portions are deferred for a future release
NAND:
- embed a struct mtd_info inside struct nand_chip
This is really long overdue; too many drivers have to do the same
silly boilerplate to allocate and link up two "independent"
structs, when in fact, everyone is assuming there is an exact 1:1
relationship between a NAND chips struct and its underlying MTD.
This aids improved helpers and should make certain abstractions
easier in the future.
Also causes a lot of churn, helped along by some automated code
transformations
- add more core support for detecting (and "correcting") bitflips in
erased pages; requires opt-in by drivers, but at least we kill a
few bad implementations and hopefully stave off future ones
- pxa3xx_nand: cleanups, a few fixes, and PM improvements
- new JZ4780 NAND driver
SPI NOR:
- provide default erase function, for controllers that just want to
send the SECTOR_ERASE command directly
- fix some module auto-loading issues with device tree
("jedec,spi-nor")
- error handling fixes
- new Mediatek QSPI flash driver
Other:
- cfi: force valid geometry Kconfig (finally!)
This one used to trip up randconfigs occasionally, since bots
aren't deterred by big scary "advanced configuration" menus
More? Probably. See the commit logs"
