Merge tag 'mtd/for-4.21' of git://git.infradead.org/linux-mtd
Pull mtd updates from Boris Brezillon: "SPI NOR Core changes: - Parse the 4BAIT SFDP section - Add a bunch of SPI NOR entries to the flash_info table - Add the concept of SFDP fixups and use it to fix a bug on MX25L25635F - A bunch of minor cleanups/comestic changes 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): * Stop to pass mtd_info objects to internal functions * Reorganize code to avoid forward declarations * Drop useless test in nand_legacy_set_defaults() * Move nand_exec_op() to internal.h * Add nand_[de]select_target() helpers * Pass the CS line to be selected in struct nand_operation * Make ->select_chip() optional when ->exec_op() is implemented * Deprecate the ->select_chip() hook * Move the ->exec_op() method to nand_controller_ops * Move ->setup_data_interface() to nand_controller_ops * Deprecate the dummy_controller field * Fix JEDEC detection * Provide a helper for polling GPIO R/B pin Raw NAND chip drivers changes: - Macronix: * Flag 1.8V AC chips with a broken GET_FEATURES(TIMINGS) Raw NAND controllers drivers changes: - Ams-delta: * Fix the error path * SPDX tag added * May be compiled with COMPILE_TEST=y * Conversion to ->exec_op() interface * Drop .IOADDR_R/W use * Use GPIO API for data I/O - Denali: * Remove denali_reset_banks() * Remove ->dev_ready() hook * Include <linux/bits.h> instead of <linux/bitops.h> * Changes to comply with the above fixes/cleanup done in the core. - FSMC: * Add an SPDX tag to replace the license text * Make conversion from chip to fsmc consistent * Fix unchecked return value in fsmc_read_page_hwecc * Changes to comply with the above fixes/cleanup done in the core. - Marvell: * Prevent 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: * Convert to SPDX identifiers - Sunxi: * Write pageprog related opcodes to the right register: WCMD_SET (fix) - Tegra: * Stop implementing ->select_chip() - VF610: * Add 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: - Remove the depreacated mt29f_spinand driver from staging. - Add support for: * Toshiba TC58CVG2S0H * GigaDevice GD5FxGQ4xA * Winbond W25N01GV JFFS2 changes: - Fix a lockdep issue MTD changes: - Rework the physmap driver to merge gpio-addr-flash and physmap_of in it - Add a new compatible for RedBoot partitions - Make sub-partitions RW if the parent partition was RO because of a mis-alignment - Add pinctrl support to the - Addition of /* fall-through */ comments where appropriate - Various minor fixes and cleanups Other changes: - Update my email address" * tag 'mtd/for-4.21' of git://git.infradead.org/linux-mtd: (108 commits) mtd: rawnand: sunxi: Write pageprog related opcodes to WCMD_SET MAINTAINERS: Update my email address mtd: rawnand: marvell: prevent timeouts on a loaded machine mtd: rawnand: omap2: Pass the parent of pdev to dma_request_chan() mtd: rawnand: Fix JEDEC detection mtd: spi-nor: Add support for is25lp016d mtd: spi-nor: parse SFDP 4-byte Address Instruction Table mtd: spi-nor: Add 4B_OPCODES flag to is25lp256 mtd: spi-nor: Add an SPDX tag to spi-nor.{c,h} mtd: spi-nor: Make the enable argument passed to set_byte() a bool mtd: spi-nor: Stop passing flash_info around mtd: spi-nor: Avoid forward declaration of internal functions mtd: spi-nor: Drop inline on all internal helpers mtd: spi-nor: Add a post BFPT fixup for MX25L25635E mtd: spi-nor: Add a post BFPT parsing fixup hook mtd: spi-nor: Add the SNOR_F_4B_OPCODES flag mtd: spi-nor: cast to u64 to avoid uint overflows mtd: spi-nor: Add support for IS25LP032/064 mtd: spi-nor: add entry for mt35xu512aba flash mtd: spi-nor: add macros related to MICRON flash ...
