[PATCH v5 00/23] mtd: nand: denali: Denali NAND IP patch bomb

[Masahiro Yamada]

This patch series intends to solve various problems.

[1] The driver just retrieves the OOB area as-is
    whereas the controller uses syndrome page layout.
[2] Many NAND chip specific parameters are hard-coded in the driver.
[3] ONFi devices are not working
[4] It can not read Bad Block Marker

Outstanding changes are:
- Fix raw/oob callbacks for syndrome page layout
- Implement setup_data_interface() callback
- Fix/implement more commands for ONFi devices
- Allow to skip the driver internal bounce buffer
- Support PIO in case DMA is not supported
- Switch from ->cmdfunc over to ->cmd_ctrl

18 patches were merged at v2.
11 patches were merged at v3.
2 patches were merged at 4.
Here is the rest of the series.
