Subject: [PATCH v2 0/8] mtd: atmel_nand: Add support for NAND Flash on SAMA5D2
Date: Fri, 15 Jan 2016 11:34:54 +0100 [thread overview]
Message-ID: <1452854102-6125-1-git-send-email-romain.izard.pro@gmail.com> (raw)
The NAND Flash controller for SAMA5D2 has small differences that make it
impossible to use the existing driver for SAMA5D3. This patchset uses the
device tree's compatible string to get those differences, and the code is
slightly modified to handle them.
Base on v4.4
To apply on the Atmel Linux 4.1 branch, support for of_device_get_match_data
needs to be backported, or the function itself open coded.
Compile tested for sama5_defconfig, and tested on SAMA5D3xek as there is no
existing SAMA5D2 board with NAND Flash memory (yet).
V2 -> V1:
- Rebase on v4.4
- Use of_device_get_match_data
- Split message cleanup
- Reword a small part of the atmel_nand device tree binding
- Use 'caps' for all private data structures
RFC -> V1:
- Split the support of 32-bit ECC on SAMA5D2 in two commits
- Fix the missing ECC strength configuration code
