*changes v8 -> v9* [PATCH 1/9] <no update from [PATCH v8 1/6]> [PATCH 2/9] <only commit log updated from [PATCH v8 2/6]> As per feedbacks from Brian Norris <computersforpeace@xxxxxxxxx> previous revision [PATCH v8 3/6] and [PATCH 4/6] are split into following sub-patches: - [PATCH 3/9] <new> replaces local reference with generic names (mtd, nand_chip) - [PATCH 4/9] <new> enables auto-detection of bus-width - [PATCH 5/9] <new> removes omap3_init_bch: populates ecc-scheme data - [PATCH 6/9] <new> removes omap3_init_bch_tail: populates ecc-layout - [PATCH 7/9] <new> replaces lib/bch.c with nand_bch.c wrapper [PATCH 8/9] <no update same as [PATCH v8 5/6] [PATCH 9/9] removed devm_free_xx functions *Changes v7 -> v8* [PATCH 1/6] <no updates> [PATCH 2/6] - updated DT parsing of "ti,nand-ecc-opts" so that its "ham1" remains compatible to "sw","hw","hw-romcode" - updated DT parsing of "ti,elm-id" to retain compatibility to "elm_id" - using of_parse_phandle() to get ELM device pointer from DT [PATCH 3..6/6] <commit log updates> *Changes v6 -> v7* [PATCH 1/6] <NEW> split from [PATCH v6 2/4] as per feedbacks from Brian Norris <computersforpeace@xxxxxxxxx> [PATCH 2/6] incorporated feedbacks from DT maintainers [PATCH 3/6] cleaned and incorporated feedbacks from Brian Norris <computersforpeace@xxxxxxxxx> [PATCH 4/6] rebasing changes and cleanup [PATCH 5/6] updated omap3430-sdp.dts [PATCH 6/6] <NEW> updated for devm_xx *Changes v5 -> v6* [PATCH 1/4]: - updated DT binding for gpmc-nand based on 'Olof Johansson's feedbacks http://lists.infradead.org/pipermail/linux-mtd/2013-August/048394.html - detection of ELM device via ti,elm-id DT node, moved to gpmc.c driver [PATCH 2/4] - removed: support for following obselete ECC schemes OMAP_ECC_HAMMING_CODE_DEFAULT (S/W based 1-bit Hamming ECC) OMAP_ECC_HAMMING_CODE_HW_ROMCODE (H/W based 1-bit Hamming ECC scheme) - updated: using omap_oobinfo as chip->ecc.layout for all ecc-schemes - clean: error messages [PATCH 3/4] cleaned to include changes for OMAP_ECC_BCH8_CODE_HW only [PATCH 4/4] updated to include DT property changes *Changes v4 -> v5* - Rebased to linux-next IMPORTANT: Need to revert commit fb1585b, [PATCH 2/4] part of previous version http://lists.infradead.org/pipermail/linux-mtd/2013-July/047441.html - Swapped PATCH-1 & PATCH-2 to maintain bisectibility & compilation dependency http://lists.infradead.org/pipermail/linux-mtd/2013-July/047461.html - PATCH-2: re-ordered call to is_elm_present() for later updates ELM driver - dropped changes in include/linux/platform_data/elm.h (not needed) - PATCH-3: re-ordered call to is_elm_present() for later updates ELM driver - Re-formated patch description (replaced tabs with white-spaces) *Changes v3 -> v4* (Resent with CC: devicetree-discuss@xxxxxxxxxxxxxxxx) - [Patch 1/3] removed MTD_NAND_OMAP_BCH8 & MTD_NAND_OMAP_BCH4 from nand/Kconfig ECC scheme selectable via nand DT (nand-ecc-opt). - [*] rebased for l2-mtd.git *Changes v2 -> v3* (Resent with Author Name fixed) - PATCH-1: re-arranged code to remove redundancy, added NAND_BUSWIDTH_AUTO - PATCH-2: updated nand-ecc-opt DT mapping and Documentation - PATCH-3: code-cleaning + changes to match PATCH-1 - PATCH-4 <DROPPED> update DT attribute for ti,nand-ecc-opt - received feedback to keep DT mapping independent of linuxism - PATCH-4:<NEW> : ARM: dts: AM33xx: updated default ECC scheme in nand-ecc-opt - independent patch for AM335x-evm.dts update based on PATCH-2 *Changes v1 -> v2* added [PATCH 3/4] and [PATCH 4/4] After this patch series, omap2-nand driver will supports following ECC schemes: +---------------------------------------+---------------+---------------+ | ECC scheme |ECC calculation|Error detection| +---------------------------------------+---------------+---------------+ |OMAP_ECC_HAM1_CODE_HW |H/W (GPMC) |S/W | +---------------------------------------+---------------+---------------+ |OMAP_ECC_BCH4_CODE_HW_DETECTION_SW |H/W (GPMC) |S/W (lib/bch.c)| | (needs CONFIG_MTD_NAND_ECC_BCH) | | | | | | | |OMAP_ECC_BCH4_CODE_HW |H/W (GPMC) |H/W (ELM) | | (needs CONFIG_MTD_NAND_OMAP_BCH && | | | | ti,elm-id) | | | +---------------------------------------+---------------+---------------+ |OMAP_ECC_BCH8_CODE_HW_DETECTION_SW |H/W (GPMC) |S/W (lib/bch.c)| | (needs CONFIG_MTD_NAND_ECC_BCH) | | | | | | | |OMAP_ECC_BCH8_CODE_HW |H/W (GPMC) |H/W (ELM) | | (needs CONFIG_MTD_NAND_OMAP_BCH && | | | | ti,elm-id) | | | +---------------------------------------+---------------+---------------+ Pekon Gupta (9): mtd: nand: omap: combine different flavours of 1-bit hamming ecc schemes ARM: OMAP2+: cleaned-up DT support of various ECC schemes mtd: nand: omap: cleanup: replace local references with generic framework names mtd: nand: omap: enable auto-detection of bus-width for omap-nand drivers mtd:nand:omap2: clean-up BCHx_HW and BCHx_SW ECC configurations in device_probe mtd: nand: omap: clean-up ecc layout for BCH ecc schemes mtd: nand: omap: use drivers/mtd/nand/nand_bch.c wrapper for BCH ECC instead of lib/bch.c ARM: dts: AM33xx: updated default ECC scheme in nand-ecc-opt mtd: nand: omap: updated devm_xx for all resource allocation and free calls .../devicetree/bindings/mtd/gpmc-nand.txt | 16 +- arch/arm/boot/dts/am335x-evm.dts | 3 +- arch/arm/boot/dts/omap3430-sdp.dts | 2 +- arch/arm/mach-omap2/board-flash.c | 2 +- arch/arm/mach-omap2/gpmc.c | 47 +- drivers/mtd/nand/Kconfig | 30 +- drivers/mtd/nand/omap2.c | 623 +++++++++------------ include/linux/platform_data/mtd-nand-omap2.h | 18 +- 8 files changed, 339 insertions(+), 402 deletions(-) -- 1.8.1 -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
