Subject: [PATCH v2 0/2] riscv: spacemit: add i2c support to K1 SoC
Date: Mon, 28 Oct 2024 13:32:18 +0800 [thread overview]
Message-ID: <20241028053220.346283-1-TroyMitchell988@gmail.com> (raw)
Hi all,
This patch implements I2C driver for the SpacemiT K1 SoC,
providing basic support for I2C read/write communication which
compatible with standard I2C bus specifications.
In this version, the driver defaults to use fast-speed-mode and
interrupts for transmission, and does not support DMA, high-speed mode, or FIFO.
The docs of I2C can be found here, in chapter 16.1 I2C [1]
