Help text

This driver manages the muxing between the 2 OSPI busses and the 2 output ports. There are 4 possible muxing configurations: - direct mode (no multiplexing): OSPI1 output is on port 1 and OSPI2 output is on port 2 - OSPI1 and OSPI2 are multiplexed over the same output port 1 - swapped mode (no multiplexing), OSPI1 output is on port 2, OSPI2 output is on port 1 - OSPI1 and OSPI2 are multiplexed over the same output port 2 It also manages : - the split of the memory area shared between the 2 OSPI instances. - chip select selection override. - the time between 2 transactions in multiplexed mode.
