Merge tag 'nand/for-4.21' of git://git.infradead.org/linux-mtd into mtd/next
NAND core changes: - kernel-doc miscellaneous fixes. - Third batch of fixes/cleanup to the raw NAND core impacting various controller drivers (ams-delta, marvell, fsmc, denali, tegra, vf610): * Stopping to pass mtd_info objects to internal functions * Reorganizing code to avoid forward declarations * Dropping useless test in nand_legacy_set_defaults() * Moving nand_exec_op() to internal.h * Adding nand_[de]select_target() helpers * Passing the CS line to be selected in struct nand_operation * Making ->select_chip() optional when ->exec_op() is implemented * Deprecating the ->select_chip() hook * Moving the ->exec_op() method to nand_controller_ops * Moving ->setup_data_interface() to nand_controller_ops * Deprecating the dummy_controller field * Fixing JEDEC detection * Providing a helper for polling GPIO R/B pin Raw NAND chip drivers changes: - Macronix: * Flagging 1.8V AC chips with a broken GET_FEATURES(TIMINGS) Raw NAND controllers drivers changes: - Ams-delta: * Fixing the error path * SPDX tag added * May be compiled with COMPILE_TEST=y * Conversion to ->exec_op() interface * Dropping .IOADDR_R/W use * Use GPIO API for data I/O - Denali: * Removing denali_reset_banks() * Removing ->dev_ready() hook * Including <linux/bits.h> instead of <linux/bitops.h> * Changes to comply with the above fixes/cleanup done in the core. - FSMC: * Adding an SPDX tag to replace the license text * Making conversion from chip to fsmc consistent * Fixing unchecked return value in fsmc_read_page_hwecc * Changes to comply with the above fixes/cleanup done in the core. - Marvell: * Preventing timeouts on a loaded machine (fix) * Changes to comply with the above fixes/cleanup done in the core. - OMAP2: * Pass the parent of pdev to dma_request_chan() (fix) - R852: * Use generic DMA API - sh_flctl: * Converting to SPDX identifiers - Sunxi: * Write pageprog related opcodes to the right register: WCMD_SET (fix) - Tegra: * Stop implementing ->select_chip() - VF610: * Adding an SPDX tag to replace the license text * Changes to comply with the above fixes/cleanup done in the core. - Various trivial/spelling/coding style fixes. SPI-NAND drivers changes: - Removing the depreacated mt29f_spinand driver from staging. - Adding support for: * Toshiba TC58CVG2S0H * GigaDevice GD5FxGQ4xA * Winbond W25N01GV
