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.

mtd: physmap_of: assign parent for the concatenated MTD

2015-11-11T21:59:08Z

If there is more than one map region for this device, then the concatenated MTD will not have a parent device assigned to it -- only the sub-devices (which are not actually registered with the framework) will have their parents assigned. Let's assign the concatenated device correctly. Signed-off-by: Brian Norris Reviewed-by: Boris Brezillon

mtd: drop unnecessary partition parser data

2015-11-11T21:58:59Z

We should assign the MTD dev.of_node instead of the parser data field. This gets us the equivalent partition parser behavior with fewer special fields and parameter passing. Also convert several of these to mtd_device_register(), since we don't need the 2nd and 3rd parameters anymore. Signed-off-by: Brian Norris Reviewed-by: Marek Vasut Reviewed-by: Boris Brezillon

mtd: maps: sa1100-flash: show parent device in sysfs

2015-10-13T19:56:24Z

Fix a bug where mtd parent device symlinks aren't shown in sysfs. While at it, make use of the default owner value set by mtdcore. Incidentally, it seems the owner field in the concatenated mtds is not actually used, so this shouldn't make much of a difference anyway. Signed-off-by: Frans Klaver Signed-off-by: Brian Norris
