DMA is used for burst data transfer operation, also DMA HW supports aligned 32bit memory address and aligned data access by default. DMA burst of 8 supported. Data register used to support the read/write operation from/to device. NAND controller also supports in-built HW ECC engine. NAND controller driver implements ->exec_op() to replace legacy hooks, these specific call-back method to execute NAND operations. Thanks Boris, Andy and Arnd for the review comments and suggestions. --- v8: - fix the kbuild bot warnings - correct the typo's v7: - indentation issue is fixed - add error check for retrieve the resource from dt - Rob's review comments addressed - dt-schema build issue fixed with upgraded dt-schema v6: - update EBU_ADDR_SELx register base value build it from DT - Add tabs in in Kconfig - Rob's review comments addressed in YAML file - add addr_sel0 and addr_sel1 reg-names in YAML example v5: - replace by 'HSNAND_CLE_OFFS | HSNAND_CS_OFFS' to NAND_WRITE_CMD and NAND_WRITE_ADDR - remove the unused macros - update EBU_ADDR_MASK(x) macro - update the EBU_ADDR_SELx register values to be written - add the example in YAML file v4: - add ebu_nand_cs structure for multiple-CS support - mask/offset encoding for 0x51 value - update macro HSNAND_CTL_ENABLE_ECC - drop the op argument and un-used macros. - updated the datatype and macros - add function disable nand module - remove ebu_host->dma_rx = NULL; - rename MMIO address range variables to ebu and hsnand - implement ->setup_data_interface() - update label err_cleanup_nand and err_cleanup_dma - add return value check in the nand_remove function - add/remove tabs and spaces as per coding standard - encoded CS ids by reg property v3: - Add depends on MACRO in Kconfig - file name update in Makefile - file name update to intel-nand-controller - modification of MACRO divided like EBU, HSNAND and NAND - add NAND_ALE_OFFS, NAND_CLE_OFFS and NAND_CS_OFFS - rename lgm_ to ebu_ and _va suffix is removed in the whole file - rename structure and varaibles as per review comments. - remove lgm_read_byte(), lgm_dev_ready() and cmd_ctrl() un-used function - update in exec_op() as per review comments - rename function lgm_dma_exit() by lgm_dma_cleanup() - hardcoded magic value for base and offset replaced by MACRO defined - mtd_device_unregister() + nand_cleanup() instead of nand_release() v2: - implement the ->exec_op() to replaces the legacy hook-up. - update the commit message - YAML compatible string update to intel, lgm-nand-controller - add MIPS maintainers and xway_nand driver author in CC v1: - initial version Ramuthevar Vadivel Murugan (2): dt-bindings: mtd: Add Nand Flash Controller support for Intel LGM SoC mtd: rawnand: Add NAND controller support on Intel LGM SoC .../devicetree/bindings/mtd/intel,lgm-nand.yaml | 91 +++ drivers/mtd/nand/raw/Kconfig | 8 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/intel-nand-controller.c | 747 +++++++++++++++++++++ 4 files changed, 847 insertions(+) create mode 100644 Documentation/devicetree/bindings/mtd/intel,lgm-nand.yaml create mode 100644 drivers/mtd/nand/raw/intel-nand-controller.c -- 2.11.0 ______________________________________________________ Linux MTD discussion mailing list http://lists.infradead.org/mailman/listinfo/linux-mtd/
