3372 * Controls whether the I2C is enabled. Software can disable I2C while it is
3373 * active. However, it is important that care be taken to ensure that I2C is
3374 * disabled properly. When the I2C is disabled, the following occurs:
3375 *
3376 * The TX FIFO and RX FIFO get flushed. Status bits in the IC_INTR_STAT register
3377 * are still active until I2C goes into IDLE state. If the module is transmitting,
3378 * it stops as well as deletes the contents of the transmit buffer after the
3379 * current transfer is complete. If the module is receiving, the I2C stops the
3380 * current transfer at the end of the current byte and does not acknowledge the
3381 * transfer. The l4_sp_clk synchronizes pclk and ic_clk. The register
3382 * ic_enable_status is added to allow software to determine when the hardware has
3383 * completely shutdown in response to the IC_ENABLE register being set from 1 to 0.
3384 * Only one register is required to be monitored. Procedure for Disabling I2C
3385 *
3386 * 1. Define a timer interval (ti2c_poll) equal to the 10 times the signaling
3387 * period for the highest I2C transfer speed used in the system and supported by
3388 * I2C. For example, if the highest I2C transfer mode is 400 kb/s, then this
3389 * ti2c_poll is 25us.
3390 *
3391 * 2. Define a maximum time-out parameter, MAX_T_POLL_COUNT, such that if any
3392 * repeated polling operation exceeds this maximum value, an error is reported. 3.
3393 * Execute a blocking thread/process/function that prevents any further I2C master
3394 * transactions to be started by software, but allows any pending transfers to be
3395 * completed.
3396 *
3397 * 4. The variable POLL_COUNT is initialized to zero. 5. Set IC_ENABLE to 0.
3398 *
3399 * 6. Read the IC_ENABLE_STATUS register and test the IC_EN bit (bit 0). Increment
3400 * POLL_COUNT by one. If POLL_COUNT >= MAX_T_POLL_COUNT, exit with the relevant
3401 * error code.
3402 *
3403 * 7. If IC_ENABLE_STATUS[0] is 1, then sleep for ti2c_poll and proceed to the
3404 * previous step. Otherwise, exit with a relevant success code.
