Background from cover letter for RFC[1]. The trend has been around Octal NOR Flash lately and the latest mainline already supports 1-1-8 and 1-8-8 modes. Boris opened a discussion on how we should support stateful modes (X-X-X and XD-XD-XD, where X is the bus width and D means Double Transfer Rate). JESD216C has defined specification for Octal 8S-8S-8S and 8D-8D-8D. Based on JEDEC216C Basic Flash Parameter Table (BFPT) driver extract: DWORD-18: command and command extension type. DWORD-19: enable 8S-8S-8S/8D-8D-8D mode sequences by two instructions or write CFG Reg 2. DWORD-20: Maximum operation speed of device in Octal mode. and xSPI profile 1.0 table: DWORD-1: Read Fast command, the number of dummy cycles and address nbytes for Read Status Register command. DWORD-2: Read/Write volatile Register command for CFG Reg2. DWORD-4 and DWORD-5: dummy cycles used for various frequencies. The first set of patches is according to JESD216C adding Double Transfer Rate(DTR) fields, extension command and command bytes number to the spi_mem_op struct. This is from Boris patchset. The second set of patches parse the xSPI profile 1.0 table for parameters needed in Octal 8D-8D-8D mode. The third set of patches extract BFPT DWORD018,19,20 and define the relevant macros and enum in spi-nor layer for Octal 8S-8S-8S and 8D-8D-8D mode operation. Parts of these are refer to Boris patchset but we enable Octal 8D-8D-8D mode in spi_nor_late_init_params() rather than Boris's adding a change_mode() call-back function. The last set of patches in the series support Macronix mx25uw51245g to tweak flash parameters a correct dummy cycles set for various frequency. Also patched spi-mxic driver for testing on Macronix's Zynq PicoZed board with Macronix's SPI controller (spi-mxic.c) and mx25uw51245g Octal flash. [1] https://patchwork.ozlabs.org/cover/982926/ Summary of change log --------------------- v2: Parse BFPT & xSPI table for Octal 8D-8D-8D mode parameters and enable Octal mode in spi_nor_late_init_params(). Using Macros in spi_nor_spimem_read_data, spi_nor_spimem_write_data and so on by Vignesh comments. v1: Without parsing BFPT & xSPI profile 1.0 table and enter Octal 8D-8D-8D mode directly in spi_nor_fixups hooks. thnaks for your time and review. best regards, Mason Mason Yang (5): mtd: spi-nor: Add support for Octal 8D-8D-8D mode mtd: spi-nor: sfdp: Add support for xSPI profile 1.0 table mtd: spi-nor: Parse BFPT DWORD-18,19 and 20 for Octal 8D-8D-8D mode mtd: spi-nor: macronix: Add Octal 8D-8D-8D supports for Macronix mx25uw51245g spi: mxic: Patch for Octal 8D-8D-8D mode support drivers/mtd/spi-nor/core.c | 220 ++++++++++++++++++++++++++++++++++++++-- drivers/mtd/spi-nor/core.h | 31 ++++++ drivers/mtd/spi-nor/macronix.c | 41 ++++++++ drivers/mtd/spi-nor/sfdp.c | 222 ++++++++++++++++++++++++++++++++++++++++- drivers/mtd/spi-nor/sfdp.h | 16 ++- drivers/spi/spi-mem.c | 8 +- drivers/spi/spi-mxic.c | 101 +++++++++++++------ include/linux/mtd/spi-nor.h | 51 +++++++++- include/linux/spi/spi-mem.h | 13 +++ 9 files changed, 654 insertions(+), 49 deletions(-) -- 1.9.1
