- Updated to include I2C1 in IRQ bindings. - Modified to increase IRQ group width and add I2C1 interrupt. - Enhanced to include I2C formal properties and adjust timeouts. - Added I2C-related source files to the formal verification flow. - Updated DMA wrapper in to handle I2C DMA signals. - Created a new testbench for I2C functionality verification. - Implemented I2C helper functions in for testing. - Added I2C tests in to validate controller behavior and recovery. - Updated existing tests to accommodate changes in DMA and IRQ handling.
