Subject: [PATCH v4 0/4] i2c: add support for Andes platform
Date: Mon, 30 Mar 2026 15:30:30 +0800	[thread overview]
Message-ID: <20260330-atciic100-v4-0-d40822f63e4e@andestech.com> (raw)

This patch series adds I2C support to Andes platform, such as AE350 and
QiLai SoC.

Signed-off-by: Ben Zong-You Xie <ben717@andestech.com>

Changes in v4:
- Rebased on andi.shyti/i2c/i2c-host-next.
- (1/4)
  - Added Conor's acked by tag.

- Link to v3: https://patch.msgid.link/20260128-atciic100-v3-0-8c002fcc2bb4@andestech.com

Changes in v3:
- (1/4)
  - Rewrote the commit message to provide a detailed hardware
    description and explain the relationship between the ATCIIC100 IP,
    the AE350 platform, and the QiLai SoC. (Krzysztof)

- Link to v2: https://patch.msgid.link/20260122-atciic100-v2-0-7559136d07cf@andestech.com

Changes in v2:
- ATCIIC100 is the hardware name for the Andes I2C controller and was used
  throughout v1. However, since Device Tree bindings should reflect the hardware
  identity and driver/config naming typically follows the i2c-<soc/platform>
  convention, this version replaces occurrences of "atciic100" with more
  appropriate names, such as "i2c-andes" or "andes_i2c," to align with upstream
  standards.
- Updated cover letter title and the description.
- Rebased on andi.shyti/i2c/i2c-host-next.
- (1/4)
  - Updated the title and the description of the patch.
  - Specified what the hardware is, and modify the title and compatibles. (Krzysztof)
  - Corrected device register size.
- (2/4)
  - Updated the title and the description of the patch.
  - Replaced the readl/writel operations with regmap APIs.
  - Replaced all occurrences of atciic100 with proper names.
  - Used module_platform_driver() to initialize. (Andi)
  - Moved CONFIG_I2C_ANDES (CONFIG_I2C_ATCIIC100 in v1) to the
    "Embedded system I2C/SMBus host controller drivers" section.
  - Made CONFIG_I2C_ANDES depend on ARCH_ANDES
- (3/4) (new)
  - Added an entry to the MAINTAINERS file.
- (4/4) (new)
  - Added the I2C node to QiLai DTS.
