Merge tag 'for-linus-20171120' of git://git.infradead.org/linux-mtd
Pull MTD updates from Richard Weinberger: "General changes: - Unconfuse get_unmapped_area and point/unpoint driver methods - New partition parser: sharpslpart - Kill GENERIC_IO - Various fixes NAND changes: - Add a flag to mark NANDs that require 3 address cycles to encode a page address - Set a default ECC/free layout when NAND_ECC_NONE is requested - Fix a bug in panic_nand_write() - Another batch of cleanups for the denali driver - Fix PM support in the atmel driver - Remove support for platform data in the omap driver - Fix subpage write in the omap driver - Fix irq handling in the mtk driver - Change link order of mtk_ecc and mtk_nand drivers to speed up boot time - Change log level of ECC error messages in the mxc driver - Patch the pxa3xx driver to support Armada 8k platforms - Add BAM DMA support to the qcom driver - Convert gpio-nand to the GPIO desc API - Fix ECC handling in the mt29f driver SPI-NOR changes: - Introduce system power management support - New mechanism to select the proper .quad_enable() hook by JEDEC ID, when needed, instead of only by manufacturer ID - Add support to new memory parts from Gigadevice, Winbond, Macronix and Everspin - Maintainance for Cadence, Intel, Mediatek and STM32 drivers" * tag 'for-linus-20171120' of git://git.infradead.org/linux-mtd: (85 commits) mtd: Avoid probe failures when mtd->dbg.dfs_dir is invalid mtd: sharpslpart: Add sharpslpart partition parser mtd: Add sanity checks in mtd_write/read_oob() mtd: remove the get_unmapped_area method mtd: implement mtd_get_unmapped_area() using the point method mtd: chips/map_rom.c: implement point and unpoint methods mtd: chips/map_ram.c: implement point and unpoint methods mtd: mtdram: properly handle the phys argument in the point method mtd: mtdswap: fix spelling mistake: 'TRESHOLD' -> 'THRESHOLD' mtd: slram: use memremap() instead of ioremap() kconfig: kill off GENERIC_IO option mtd: Fix C++ comment in include/linux/mtd/mtd.h mtd: constify mtd_partition mtd: plat-ram: Replace manual resource management by devm mtd: nand: Fix writing mtdoops to nand flash. mtd: intel-spi: Add Intel Lewisburg PCH SPI super SKU PCI ID mtd: nand: mtk: fix infinite ECC decode IRQ issue mtd: spi-nor: Add support for mr25h128 mtd: nand: mtk: change the compile sequence of mtk_nand.o and mtk_ecc.o mtd: spi-nor: enable 4B opcodes for mx66l51235l ...
