This should be just &am3358_pinmux as you already include it.

It would better to claim these pins in the dcan driver entry
rather than set them as pins enabled by the pinctrl driver.
The reason is that in case you want to enable runtime PM related
stuff, like some more advanced wake-up features, for the rx pin
you can do it in the driver.
Then one nit.. Please lowercase all hex number in this series as that's the style
here.

Tony
