(Krzysztof)\n\n- Link to v2: https://patch.msgid.link/20260122-atciic100-v2-0-7559136d07cf@andestech.com\n\nChanges in v2:\n- ATCIIC100 is the hardware name for the Andes I2C controller and was used\n throughout v1. However, since Device Tree bindings should reflect the hardware\n identity and driver/config naming typically follows the i2c-<soc/platform>\n convention, this version replaces occurrences of \"atciic100\" with more\n appropriate names, such as \"i2c-andes\" or \"andes_i2c,\" to align with upstream\n standards.\n- Updated cover letter title and the description.\n- Rebased on andi.shyti/i2c/i2c-host-next.\n- (1/4)\n - Updated the title and the description of the patch.\n - Specified what the hardware is, and modify the title and compatibles. (Krzysztof)\n - Corrected device register size.\n- (2/4)\n - Updated the title and the description of the patch.\n - Replaced the readl/writel operations with regmap APIs.\n - Replaced all occurrences of atciic100 with proper names.\n - Used module_platform_driver() to initialize. (Andi)\n - Moved CONFIG_I2C_ANDES (CONFIG_I2C_ATCIIC100 in v1) to the\n \"Embedded system I2C/SMBus host controller drivers\" section.\n - Made CONFIG_I2C_ANDES depend on ARCH_ANDES\n- (3/4) (new)\n - Added an entry to the MAINTAINERS file.\n- (4/4) (new)\n - Added the I2C node to QiLai DTS.\n\n- Link to v1: https://patch.msgid.link/20250207021923.2912373-1-ben717@andestech.com\n\n---\nBen Zong-You Xie (4):\n dt-bindings: i2c: add support for AE350 I2C controller\n i2c: add Andes I2C driver support\n MAINTAINERS: add an entry for Andes I2C driver\n riscv: dts: andes: qilai: add I2C controller\n\n .../bindings/i2c/andestech,ae350-i2c.yaml | 45 +++\n MAINTAINERS | 6 +\n arch/riscv/boot/dts/andes/qilai.dtsi | 7 +\n drivers/i2c/busses/Kconfig | 10 +\n drivers/i2c/busses/Makefile | 1 +\n drivers/i2c/busses/i2c-andes.c | 341 +++++++++++++++++++++\n 6 files changed, 410 insertions(+)\n---\nbase-commit: 46ec065d8610c5e8d11a8b205a6b7bd3c40d46b8\nchange-id: 20260120-atciic100-da3ec68f7bb4\n\nBest regards,\n-- \nBen Zong-You Xie <ben717@andestech.com>" }
