chips. The UART4 device referenced from the TRM will show up as ttyO3.
This was tested on an AM3505.

I am trying to make uart4 working on a am3517 with mainline kernel
(3.3+, your patch is merged). However, on my board the uart4 pins are
shared with the camera, and not with SD, as maybe is more common. I set
the pinmux to switch the pins (gpio_95 / gpio_96 / gpio_97 /gpio_98) to
the uart4, and ttyO3 is registered and available, and thanks your patch
both clocks iclk and fclk are active. However, I cannot see activity on
the tx line if I try to send some characters.
Maybe do you use the same pinmux and am I forgetting something else ?
