Changes in v9: - Change the compatible to 'loongson,ls1*-nand-controller'. - Rename the dt-binding file to loongson,ls1b-nand-controller.yaml. - Update MAINTAINERS file accordingly. - Some minor adjustments. - Rebasing due to recent upstream changes. - Link to v8: https://lore.kernel.org/r/20240808-loongson1-nand-v8-0-c96dea418b41@gmail.com Changes in v8: - Add a description part. - Adjust the compatible because the match data for ls1c-nfc differs from ls1b-nfc. - Mark 'nand-use-soft-ecc-engine' and 'nand-ecc-algo' as mandatory. - Delete the superfluous blank lines. - Drop NAND_MONOLITHIC_READ and add support for real subpage read instead. - Simplify the logic of ls1b_nand_parse_address() and ls1c_nand_parse_address(). - Split ls1x_nand_set_controller() into ls1x_nand_parse_instructions() and ls1x_nand_trigger_op(). - Implement ls1x_nand_op_cmd_mapping() to convert the opcodes instead of forcing them. - Add ls1x_nand_check_op(). - Remove struct ls1x_nand after moving its members to struct ls1x_nfc. - Add the prefix 'LS1X_' for all registers and their bits. - Drop the macros: nand_readl() and nand_writel(). - Some minor fixes and improvements. - Link to v7: https://lore.kernel.org/r/20240430-loongson1-nand-v7-0-60787c314fa4@gmail.com Changes in v7: - Rename the file to loongson,ls1b-nfc.yaml - Rename the Kconfig dependency to LOONGSON1_APB_DMA - Link to v6: https://lore.kernel.org/r/20240327-loongson1-nand-v6-0-7f9311cef020@gmail.com Changes in v6: - Amend Kconfig - Add the dt-binding document - Modify nand_read_subpage() to allow subpage read by a single operation - Add DT support for driver - Use DT data instead of platform data - Remove MAX_ID_SIZE - Remove case NAND_OP_CMD_INSTR in ls1x_nand_set_controller() - Move ECC configuration to ls1x_nand_attach_chip() - Rename variable "nand" to "ls1x" - Rename variable "nc" to "nfc" - Some minor fixes - Link to v5: https://lore.kernel.org/all/20210520224213.7907-1-keguang.zhang@gmail.com Changes in v5: - Update the driver to fit the raw NAND framework. - Implement exec_op() instead of legacy cmdfunc(). - Use dma_request_chan() instead of dma_request_channel(). - Some minor fixes and cleanups. Changes in v4: - Retrieve the controller from nand_hw_control. Changes in v3: - Replace __raw_readl/__raw_writel with readl/writel. - Split ls1x_nand into two structures: ls1x_nand_chip and ls1x_nand_controller. Changes in v2: - Modify the dependency in Kconfig due to the changes of DMA module.
