[v4,0/6] mtd: rawnand: add NVIDIA Tegra NAND flash support

The most notable change in this forth revision is the addition of raw page and oob read/write accessors which support DMA. After looking a bit closer into the U-Boot implementation of the Tegra NAND driver I realized that in my previous attempts I enabled SKIP_SPARE_EN which seems not to work when not using ECC modes. A bad block scan of a 1GiB chip dropped from 3.9s to 0.2s. The MTD kernel module tests seem to pass still: ================================================= mtd_speedtest: MTD device: 4 mtd_speedtest: MTD device size 1068498944, eraseblock size 262144, page

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 Lucas Stach (1): ARM: dts: tegra: add Tegra20 NAND flash controller node Stefan Agner (5): mtd: rawnand:
