lib: utils/i2c: Use heap in DesignWare and SiFive I2C drivers

2023-06-05T10:25:45Z

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: utils/i2c: Add minimal StarFive jh7110 I2C driver

2023-03-09T15:30:57Z

Starfive JH7110 I2C IP is synopsys designware. Minimum StarFIve 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. Signed-off-by: Minda Chen 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: 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.
