i2c-dw-linux-adapter

Under the cross-kernel driver framework, the Linux driver adaptation layer implemented for designware apb I2C

How to use

Clone repo

In your linux directory, clone this project

cd drivers/i2c/busses
git clone https://github.com/guoweikang/i2c-dw-linux-adapter.git

Linux support Cargo

The cross-kernel driver framework follows a componentized design and uses cargo to resolve component dependencies, so it is necessary to add R4L support for cargo construction.

step1: Patch linux support cargo build

patch on patches/0001_linux_support_cargo.diff

step2: Add Makefile for adapter dir

Add this line into linux/drivers/i2c/busses/Makefile

obj-$(CONFIG_RUST)     += i2c-dw-linux-adapter/

you can also replace CONFIG_RUST with your own defin, like this from original I2C_DESIGNWARE_PLATFORM Kconfig

config I2C_DESIGNWARE_PLATFORM_RUST
	tristate "Synopsys DesignWare Platform with RUST"
    depends on (ACPI && COMMON_CLK) || !ACPI
    depends on RUST
	help
      If you say yes to this option, support will be included for the
      Synopsys DesignWare I2C adapter.

      This driver can also be built as a module.  If so, the module
      will be called i2c-designware-platform.      

note: if you want to use RUST driver,remeber disable C driver

step3: add Makefile for adapter that use cargo build
