This series refactors and cleans ELM driver which is used by Hardware based BCHx ecc-schemes. - Undo: introduction of 'struct mtd_info' and 'struct nand_chip'. Instead keep ELM driver independent of mtd_info and nand_chip structs and pass only required ECC configurations as elm_config() arguments elm_config(..., int ecc_steps, int ecc_step_size, int ecc_step_bytes) - Undo: re-writing of elm_load_syndrome() ECC register configurations. *changes v3 -> v4 [1]* - in-corporated feedbacks from Brian Norris - updated: use 'pr_fmt(fmt)' to suffix DRIVER_NAME - removed: local 'eccsteps' in ELM driver, instead using nand_chip->ecc.steps - undo: irrelavant white-space changes [1] http://lists.infradead.org/pipermail/linux-mtd/2013-November/050242.html Pekon Gupta (4): mtd: devices: elm: check for hardware engine's design constraints mtd: devices: elm: clean elm_load_syndrome mtd: devices: elm: configure parallel channels based on ecc_steps mtd: devices: elm: update DRIVER_NAME as "omap-elm" drivers/mtd/devices/elm.c | 43 ++++++++++++++++++++++++++++----------- drivers/mtd/nand/omap2.c | 9 +++++--- include/linux/platform_data/elm.h | 10 ++------- 3 files changed, 39 insertions(+), 23 deletions(-) -- 1.8.5.1.163.gd7aced9
