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

treewide: Make carray arrays const and NULL-terminated

2024-11-28T11:39:17Z

This allows the compiler to generate significantly better code, because it does not have to maintain either the loop counter or loop limit. Plus there are half as many symbols to relocate. This also simplifies passing carray arrays to helper functions. Signed-off-by: Samuel Holland Reviewed-by: Anup Patel

lib: utils/i2c: Constify FDT pointers in parsing functions

Indicate that none of these functions modify the devicetree by constifying the parameter type. Signed-off-by: Samuel Holland Reviewed-by: Andrew Jones Reviewed-by: Anup Patel

lib: utils/i2c: Generate FDT i2c adapter driver list at compile-time

2022-05-13T03:56:45Z

Instead of having FDT i2c adapter driver list hard-coded in the C source, we generate it using carray.sh at compile-time. Signed-off-by: Anup Patel Reviewed-by: Atish Patra

lib: utils/i2c: Add minimal SiFive I2C driver

2021-11-12T04:59:08Z

Minimum SiFive I2C driver to read/send bytes over I2C bus. This allows querying information and perform operation of onboard PMIC, as well as power-off and reset. Tested-by: Heinrich Schuchardt Reviewed-by: Alexandre Ghiti Tested-by: Alexandre Ghiti Signed-off-by: Nikita Shubin

lib: utils/i2c: Add simple FDT based I2C framework
