I also noticed that this info is duplicated in a few places; namely, some sub-subsystems (like SPI NOR and NAND) need their own field to track the DT node, so let's have the propagate the 'MTD' DT node down for us. Besides simplifying the boilerplate throughout MTD, this series also has the side effect of producing 'of_node' symlinks in sysfs. e.g.: # ls -al /sys/class/mtd/mtd0/of_node lrwxrwxrwx 1 root root 0 Oct 26 19:17 /sys/class/mtd/mtd0/of_node -> ../../../../firmware/devicetree/base/spi@...30000/flash@0 For NAND, this potentially has some other bigger initial side effects, since nand_dt_init() handles a bit more automagically for drivers that defined their ->flash_node. But these drivers should probably convert anyway. So, please test your favorite driver! v1 -> v2: * add helper functions for getting/setting the MTD/SPI-NOR/NAND DT node * fix some build errors * drop spi_nor's flash_node field (just use the MTD of_node) Regards, Brian Brian Norris (11): mtd: add get/set of_node/flash_node helpers mtd: ofpart: grab device tree node directly from master device node mtd: {nand,spi-nor}: assign MTD of_node mtd: nand: convert to nand_set_flash_node() mtd: spi-nor: convert to spi_nor_{get,set}_flash_node() mtd: nand: drop unnecessary partition parser data mtd: spi-nor: drop unnecessary partition parser data mtd: spi-nor: drop flash_node field mtd: drop unnecessary partition parser data mtd: ofpart: drop 'of_node' partition parser data mtd: physmap_of: assign parent for the concatenated MTD drivers/mtd/devices/m25p80.c | 10 +++------- drivers/mtd/devices/mtd_dataflash.c | 5 ++--- drivers/mtd/devices/spear_smi.c | 6 ++---- drivers/mtd/devices/st_spi_fsm.c | 5 ++--- drivers/mtd/maps/lantiq-flash.c | 5 ++--- drivers/mtd/maps/physmap_of.c | 6 +++--- drivers/mtd/nand/atmel_nand.c | 7 +++---- drivers/mtd/nand/brcmnand/brcmnand.c | 5 ++--- drivers/mtd/nand/davinci_nand.c | 10 +++------- drivers/mtd/nand/fsl_elbc_nand.c | 5 ++--- drivers/mtd/nand/fsl_ifc_nand.c | 5 ++--- drivers/mtd/nand/fsl_upm.c | 5 ++--- drivers/mtd/nand/fsmc_nand.c | 9 ++++----- drivers/mtd/nand/gpio.c | 8 +++----- drivers/mtd/nand/gpmi-nand/gpmi-nand.c | 5 ++--- drivers/mtd/nand/hisi504_nand.c | 5 ++--- drivers/mtd/nand/lpc32xx_mlc.c | 7 +++---- drivers/mtd/nand/lpc32xx_slc.c | 7 +++---- drivers/mtd/nand/mpc5121_nfc.c | 5 ++--- drivers/mtd/nand/mxc_nand.c | 5 ++--- drivers/mtd/nand/nand_base.c | 3 +++ drivers/mtd/nand/ndfc.c | 5 ++--- drivers/mtd/nand/omap2.c | 6 ++---- drivers/mtd/nand/orion_nand.c | 6 ++---- drivers/mtd/nand/plat_nand.c | 5 ++--- drivers/mtd/nand/pxa3xx_nand.c | 10 +++++----- drivers/mtd/nand/sh_flctl.c | 6 ++---- drivers/mtd/nand/socrates_nand.c | 5 ++--- drivers/mtd/nand/sunxi_nand.c | 6 ++---- drivers/mtd/nand/vf610_nfc.c | 8 ++------ drivers/mtd/ofpart.c | 12 ++++-------- drivers/mtd/onenand/omap2.c | 8 +++----- drivers/mtd/spi-nor/fsl-quadspi.c | 6 ++---- drivers/mtd/spi-nor/nxp-spifi.c | 6 ++---- drivers/mtd/spi-nor/spi-nor.c | 2 +- drivers/staging/mt29f_spinand/mt29f_spinand.c | 5 ++--- include/linux/mtd/mtd.h | 11 +++++++++++ include/linux/mtd/nand.h | 11 +++++++++++ include/linux/mtd/partitions.h | 2 -- include/linux/mtd/spi-nor.h | 13 +++++++++++-- 40 files changed, 120 insertions(+), 141 deletions(-) -- 2.6.0.rc2.230.g3dd15c0 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
