OMAP reaction facing a multiple devices definition by muxing

OMAP reaction facing a multiple devices definition by muxing

[max]

Hello,

I have a question concerning the mux and the OMAP's reaction.

How does the omap reacts when you define a register for a specific
device that is already initiated as primary mode of another register ?
For example CONTROL_PADCONF_UART1_ defines the uart1 in primary mode but
when you mux the register CONTROL_PADCONF_MCBSP_CLKS into mode 5 (and
the other apropiate registers for the uart1) how does the OMAP reacts ?

Thank you for your answer. 

Best regard,

Maxime Bouré

AFAIK, it just reroutes the signal and that's it. The muxing system
does not affect the omap internal state, it's there just to route the
signals to the limited number of pins.
