i2c: mlxbf: support BlueField-3 SoC
BlueField-3 SoC has the same I2C IP logic as previous BlueField-1 and 2 SoCs but it has different registers' addresses. This is an effort to keep this driver generic across all BlueField generations. This patch breaks down the "smbus" resource into 3 separate resources to enable us to use common registers' offsets for all BlueField SoCs: struct mlxbf_i2c_resource *timer; struct mlxbf_i2c_resource *mst; struct mlxbf_i2c_resource *slv; Of course, all offsets had to be adjusted accordingly, and we took this chance to reorganize the macros depending on the register block they target. There are only 2 registers' offsets that do not fit within this schema so their offsets are passed as SoC-specific parameters: smbus_master_rs_bytes_off smbus_master_fsm_off Reviewed-by: Khalil Blaiech <kblaiech@nvidia.com> Signed-off-by: Asmaa Mnebhi <asmaa@nvidia.com> Signed-off-by: Wolfram Sang <wsa@kernel.org>
