2019-03-21mtd: rawnand: Mark expected switch fall-throughsGustavo A. R. Silva
In preparation to enabling -Wimplicit-fallthrough, mark switch cases where we are expecting to fall through. This patch fixes the following warning: drivers/mtd/nand/raw/diskonchip.c: In function ‘doc_probe’: ./include/linux/printk.h:303:2: warning: this statement may fall through [-Wimplicit-fallthrough=] printk(KERN_ERR pr_fmt(fmt), ##__VA_ARGS__) ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/nand/raw/diskonchip.c:1479:4: note: in expansion of macro ‘pr_err’ pr_err("DiskOnChip Millennium Plus 32MB is not supported, ignoring.\n"); ^~~~~~ drivers/mtd/nand/raw/diskonchip.c:1480:3: note: here default: ^~~~~~~ drivers/mtd/nand/raw/nandsim.c: In function ‘ns_init_module’: drivers/mtd/nand/raw/nandsim.c:2254:22: warning: this statement may fall through [-Wimplicit-fallthrough=] chip->bbt_options |= NAND_BBT_NO_OOB; drivers/mtd/nand/raw/nandsim.c:2255:2: note: here case 1: ^~~~ drivers/mtd/nand/raw/nuc900_nand.c: In function ‘nuc900_nand_command_lp’: ./arch/x86/include/asm/io.h:91:22: warning: this statement may fall through [-Wimplicit-fallthrough=] #define __raw_writel __writel drivers/mtd/nand/raw/nuc900_nand.c:52:2: note: in expansion of macro ‘__raw_writel’ __raw_writel((val), (dev)->reg + REG_SMCMD) ^~~~~~~~~~~~ drivers/mtd/nand/raw/nuc900_nand.c:196:3: note: in expansion of macro ‘write_cmd_reg’ write_cmd_reg(nand, NAND_CMD_READSTART); ^~~~~~~~~~~~~ drivers/mtd/nand/raw/nuc900_nand.c:197:2: note: here default: ^~~~~~~ drivers/mtd/nand/raw/omap_elm.c: In function ‘elm_context_restore’: drivers/mtd/nand/raw/omap_elm.c:512:4: warning: this statement may fall through [-Wimplicit-fallthrough=] elm_write_reg(info, ELM_SYNDROME_FRAGMENT_4 + offset, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ regs->elm_syndrome_fragment_4[i]); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/nand/raw/omap_elm.c:514:3: note: here case BCH8_ECC: ^~~~ drivers/mtd/nand/raw/omap_elm.c:517:4: warning: this statement may fall through [-Wimplicit-fallthrough=] elm_write_reg(info, ELM_SYNDROME_FRAGMENT_2 + offset, ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ regs->elm_syndrome_fragment_2[i]); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/nand/raw/omap_elm.c:519:3: note: here case BCH4_ECC: ^~~~ drivers/mtd/nand/raw/omap_elm.c: In function ‘elm_context_save’: drivers/mtd/nand/raw/omap_elm.c:466:37: warning: this statement may fall through [-Wimplicit-fallthrough=] regs->elm_syndrome_fragment_4[i] = elm_read_reg(info, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ ELM_SYNDROME_FRAGMENT_4 + offset); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/nand/raw/omap_elm.c:468:3: note: here case BCH8_ECC: ^~~~ drivers/mtd/nand/raw/omap_elm.c:471:37: warning: this statement may fall through [-Wimplicit-fallthrough=] regs->elm_syndrome_fragment_2[i] = elm_read_reg(info, ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~ ELM_SYNDROME_FRAGMENT_2 + offset); ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ drivers/mtd/nand/raw/omap_elm.c:473:3: note: here case BCH4_ECC: ^~~~ Warning level 3 was used: -Wimplicit-fallthrough=3 This patch is part of the ongoing efforts to enabling -Wimplicit-fallthrough.

2018-10-03mtd: rawnand: Deprecate ->chip_delayBoris Brezillon
The wait timeouts and delays are directly extracted from the NAND timings and ->chip_delay is only used in legacy path, so let's move it to the nand_legacy struct to make it clear. Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com> Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com>
