Subject: [PATCH v8 0/6] mtd: rawnand: add NVIDIA Tegra NAND flash support
Date: Sun, 24 Jun 2018 23:27:21 +0200 [thread overview]
Message-ID: <20180624212727.21672-1-stefan@agner.ch> (raw)
Eigth and hopefully final revision gets rid of nand_release() as
suggested by Boris.

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()
