Subject: [PATCH v2 0/2] i2c: Add Loongson-2K0300 I2C controller support
Date: Tue, 27 Jan 2026 10:47:55 +0800 [thread overview]
Message-ID: <cover.1769476820.git.zhoubinbin@loongson.cn> (raw)
Hi all:
This patch set describes the I2C controller integrated the
Loongson-2K0300 chip.
It has a significantly different design from the previous I2C
controller(i2c-ls2x), such as support for master-slave transfer mode,
and DMA transfers (implementation in progress), etc. Therefore, we try
to name it i2c-ls2x-v2.
Thanks.
======
V2:
Patch (1/2):
- Add Acked-by tag from Conor, thanks.
Patch (2/2):
- Reorder the definitions of read() and write();
- Adjust the calculation method for bus speed.
