## Summary Apparently there is an error on the i2c handling of the esp32s3. When there is a bus error, the master will never be able to recover (not even after a reset, since the reset control was broken). If we need to send the 9 clk, we can use the i2c reset function. This PR includes: - the fix to the reset_fsmc (do as we do on the esp32c3 and as specified in the TRM). - The improvement to not send 9 CLK every time we want to clear the fsm. ## Impact The i2c on the esp32s3 is now much faster, as we don't need to send the 9 clocks on every transaction. We also recover from failed transactions, as the reset of the fsm is done correctly. ## Testing Only manual testing: after these changes I am able to do i2c dev 1 7f on my esp32-s3-eye and it will alwais find the IMU at address 12. -- This is an automated message from the Apache Git Service.
