The core will now parse the device tree\n properties and enable or disable the randomizer accordingly\n during spinand_init.\n- Patch 3: implement the set_randomizer callback specifically for Macronix\n chips (MX35LF/UF series) to handle the vendor-specific register\n operations.\n\nv5:\n* Promoted the randomizer configuration to use generic NAND properties\n (nand-randomizer-enable and nand-randomizer-disable) instead of\n vendor-specific bindings.\n* Refactored the initialization architecture in core.c. The core framework\n is now responsible for parsing the device tree properties and deciding\n whether to enable or disable the randomizer.\n\nv4:\n* Fix a build error in spinand_randomizer_init() where a value was\n returned from a void function. (Reported by kernel test robot)\n* Update the return type to int.\n\nv3:\n* Revert the device tree property to the vendor-specific\n \"mxic,randomizer-enable\" to strictly follow vendor-specific bindings.\n\n* Update the 'set_randomizer' callback signature to accept a boolean\n 'enable' argument, allowing the feature to be explicitly enabled or\n disabled.\n\n* Switch the implementation to use the standard SET_FEATURE command\n to modify the Configuration Register (0x10), replacing the previous\n special program command method.\n\nv2:\n* Create a global NAND DT property\nCheng Ming Lin (3):\n dt-bindings: mtd: spinand: Add randomizer enable/disable properties\n mtd: spi-nand: Add support for randomizer\n mtd: spi-nand: macronix: Enable randomizer support\n\n .../devicetree/bindings/mtd/nand-chip.yaml | 8 ++++\n drivers/mtd/nand/spi/core.c | 27 +++++++++++\n drivers/mtd/nand/spi/macronix.c | 46 ++++++++++++++-----\n include/linux/mtd/spinand.h | 9 ++++\n 4 files changed, 79 insertions(+), 11 deletions(-)" }
