Eigth and hopefully final revision gets rid of nand_release() as suggested by Boris. -- Stefan Changes since v1: - Split controller and NAND chip structure - Add BCH support - Allow to select algorithm and strength using device tree - Improve HW ECC error reporting and use DEC_STATUS_BUF only - Use SPDX license identifier - Use per algorithm mtd_ooblayout_ops - Use setup_data_interface callback for NAND timing configuration Changes since v2: - Set clock rate using assigned-clocks - Use BIT() macro - Fix and improve timing calculation - Improve ECC error handling - Store OOB layout for tag area in Tegra chip structure - Update/fix bindings - Use more specific variable names (replace "value") - Introduce nand-is-boot-medium - Choose sensible ECC strenght automatically - Use wait_for_completion_timeout - Print register dump on completion timeout - Unify tegra_nand_(read|write)_page in tegra_nand_page_xfer Changes since v3: - Implement tegra_nand_(read|write)_raw using DMA - Implement tegra_nand_(read|write)_oob using DMA - Name registers according to Tegra 2 Technical Reference Manual (v02p) - Use wait_for_completion_io_timeout to account for IO - Get chip select id from device tree reg property - Clear interrupts and reinit wait queues in case command/DMA times out - Set default MTD name after nand_set_flash_node - Move MODULE_DEVICE_TABLE after declaration of tegra_nand_of_match - Make (rs|bch)_strength static Changes since v4: - Pass OOB area to nand_check_erased_ecc_chunk - Pass algorithm specific bits_per_step to tegra_nand_get_strength - Store ECC layout in chip structure - Fix pointer assignment (use NULL) - Removed obsolete header delay.h - Fixed newlines - Use non-_io variant of wait_for_completion_timeout Changes since v5: - Drop extra OOB bytes support Changes since v6: - checkpatch.pl fixes Changes since v7: - Replace nand_release() with mtd_device_unregister() + nand_cleanup() Lucas Stach (1): ARM: dts: tegra: add Tegra20 NAND flash controller node Stefan Agner (5): mtd: rawnand: add Reed-Solomon error correction algorithm mtd: rawnand: add an option to specify NAND chip as a boot device mtd: rawnand: tegra: add devicetree binding mtd: rawnand: add NVIDIA Tegra NAND Flash controller driver ARM: dts: tegra: enable NAND flash on Colibri T20 .../devicetree/bindings/mtd/nand.txt | 6 +- .../bindings/mtd/nvidia-tegra20-nand.txt | 64 + MAINTAINERS | 7 + arch/arm/boot/dts/tegra20-colibri-512.dtsi | 16 + arch/arm/boot/dts/tegra20.dtsi | 15 + drivers/mtd/nand/raw/Kconfig | 10 + drivers/mtd/nand/raw/Makefile | 1 + drivers/mtd/nand/raw/nand_base.c | 4 + drivers/mtd/nand/raw/tegra_nand.c | 1230 +++++++++++++++++ include/linux/mtd/rawnand.h | 7 + 10 files changed, 1359 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/mtd/nvidia-tegra20-nand.txt create mode 100644 drivers/mtd/nand/raw/tegra_nand.c -- 2.17.1 -- To unsubscribe from this list: send the line "unsubscribe linux-tegra" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
