lib: utils/i2c: Use fdt_driver for initialization

2024-11-28T12:08:05Z

The i2c driver subsystem does not need any extra data, so it can use `struct fdt_driver` directly. It always initializes the driver for a specific DT node. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

Let's use heap allocation in DesignWare and SiFive I2C drivers instead of using a fixed size global array. Signed-off-by: Anup Patel Reviewed-by: Andrew Jones

lib: fix pointer of type 'void *' used in arithmetic

2022-01-21T16:28:12Z

Using "void *" in arithmetic causes errors with strict compiler settings: "error: pointer of type 'void *' used in arithmetic [-Werror=pointer-arith]" Avoid these by calculating on "char *" where 1-byte data size is assumed.
