Merge tag 'spi-nor/for-5.17' into mtd/next

SPI NOR core changes:
- Add Pratyush as SPI NOR co-maintainer.
- Flash parameters initialization was done in a spaghetti way. Clean
  flash parameters initialization.
- Rework the flash_info flags and clarify where one should be used.
- Initialize all flash parameters based on JESD216 SFDP where possible.
  Flash parameters and settings that are SFDP discoverable should not be
  duplicated via flash_info flags at flash declaration.
- Remove debugfs entries that duplicate sysfs entries.

SPI NOR manufacturer drivers changes:
- Use late_init() hook in various drivers to make it clear that those
  flash parameters are either not declared in the JESD216 SFDP standard,
  or the SFDP tables which define those flash parameters are not defined
  by the flash.
- Fix mtd size for s3an flashes.
- Write 2 bytes when disabling Octal DTR mode: 1 byte long transactions are
  not allowed in 8D-8D-8D mode.

+ * @id:             the flash's ID bytes. The first three bytes are the
+ *                  JEDIC ID. JEDEC ID zero means "no ID" (mostly older chips).
+ * @id_len:         the number of bytes of ID.
+ * @sector_size:    the size listed here is what works with SPINOR_OP_SE, which
+ *                  isn't necessarily called a "sector" by the vendor.
+ * @n_sectors:      the number of sectors.
+ * @page_size:      the flash's page size.
+ * @addr_width:     the flash's address width.
+ *
+ * @parse_sfdp:     true when flash supports SFDP tables. The false value has no
+ *                  meaning. If one wants to skip the SFDP tables, one should
+ *                  instead use the SPI_NOR_SKIP_SFDP sfdp_flag.
+ * @flags:          flags that indicate support that is not defined by the
+ *                  JESD216 standard in its SFDP tables. Flag meanings:
+ *   SPI_NOR_HAS_LOCK:        flash supports lock/unlock via SR
+ *   SPI_NOR_HAS_TB:          flash SR has Top/Bottom (TB) protect bit. Must be
+ *                            used with SPI_NOR_HAS_LOCK.
+ *   SPI_NOR_TB_SR_BIT6:      Top/Bottom (TB) is bit 6 of status register.
+ *                            Must be used with SPI_NOR_HAS_TB.
+ *   SPI_NOR_4BIT_BP:         flash SR has 4 bit fields (BP0-3) for block
+ *                            protection.
+ *   SPI_NOR_BP3_SR_BIT6:     BP3 is bit 6 of status register. Must be used with
+ *                            SPI_NOR_4BIT_BP.
+ *   SPI_NOR_SWP_IS_VOLATILE: flash has volatile software write protection bits.
+ *                            Usually these will power-up in a write-protected
+ *                            state.
+ *   SPI_NOR_NO_ERASE:        no erase command needed.
+ *   NO_CHIP_ERASE:           chip does not support chip erase.
+ *   SPI_NOR_NO_FR:           can't do fastread.
+ *   USE_CLSR:                use CLSR command.
+ *   USE_FSR:                 use flag status register
+ *   SPI_NOR_XSR_RDY:         S3AN flashes have specific opcode to read the
+ *                            status register.
+ *
+ * @no_sfdp_flags:  flags that indicate support that can be discovered via SFDP.
+ *                  Used when SFDP tables are not defined in the flash. These
+ *                  flags are used together with the SPI_NOR_SKIP_SFDP flag.
+ *   SPI_NOR_SKIP_SFDP:       skip parsing of SFDP tables.
+ *   SECT_4K:                 SPINOR_OP_BE_4K works uniformly.
+ *   SECT_4K_PMC:             SPINOR_OP_BE_4K_PMC works uniformly.
+ *   SPI_NOR_DUAL_READ:       flash supports Dual Read.
+ *   SPI_NOR_QUAD_READ:       flash supports Quad Read.
+ *   SPI_NOR_OCTAL_READ:      flash supports Octal Read.
+ *   SPI_NOR_OCTAL_DTR_READ:  flash supports octal DTR Read.
+ *   SPI_NOR_OCTAL_DTR_PP:    flash supports Octal DTR Page Program.
+ *
+ * @fixup_flags:    flags that indicate support that can be discovered via SFDP
+ *                  ideally, but can not be discovered for this particular flash
+ *                  because the SFDP table that indicates this support is not
+ *                  defined by the flash. In case the table for this support is
+ *                  defined but has wrong values, one should instead use a
+ *                  post_sfdp() hook to set the SNOR_F equivalent flag.
+ *
+ *   SPI_NOR_4B_OPCODES:      use dedicated 4byte address op codes to support
+ *                            memory size above 128Mib.
+ *   SPI_NOR_IO_MODE_EN_VOLATILE: flash enables the best available I/O mode
+ *                            via a volatile bit.
+ * @mfr_flags:      manufacturer private flags. Used in the manufacturer fixup
+ *                  hooks to differentiate support between flashes of the same
+ *                  manufacturer.
+ * @otp_org:        flash's OTP organization.
+ * @fixups:         part specific fixup hooks.
