[v18,0/3] EDAC/nuvoton: Add NPCM memory controller driver

Message

Marvin Lin Jan. 11, 2023, 9:32 a.m. UTC

This patch series add DTS node, dt-bindings document and driver for memory
controller present on Nuvoton NPCM SoCs.

The memory controller supports single bit error correction and double bit
error detection (in-line ECC in which a section 1/8th of the memory device
used to store data is used for ECC storage).

Changes in v18:
  - Driver refinements
    - Adjust line breaks, order of variable declarations and destroy resources.
    - Catch weired cases by WARN_ON_ONCE.
    - Add defines for constants, and provide injection examples in comment.
  - Correct subject prefixes of patch 2/3.

Changes in v17:
  - Correct subject prefixes of patch 1/3.
  - Change dt-bindings document name to "nuvoton,npcm-memory-controller.yaml"
    and refine the document format.

Changes in v16:
  - Correct dt-bindings document path in MAINTAINERS.
  - Fix wrong indentation in driver.

Changes in v15:
  - Move dt-bindings document to memory-controllers directory and remove
    superfluous string in content title.

Changes in v14:
  - Fix compile warnings.

Changes in v13:
  - Support error injection via debugfs.
  - Fix coding style issues.
