Merge tag 'for-linus-20160112' of git://git.infradead.org/linux-mtd
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.
