Hello everyone,
I'm using a linux-fslc kernel for imx28 and I need to change the pin mux
for mine board.
I saw that is necessary to change the file imx28-evk.dts but I didnt find
many information how to change that.
In my case I just need to change the mux for these pins to output:
LED1 -> GPIO1_13 (LCD_D13);
LED2 -> GPIO1_13 (LCD_D12);
LED3 -> GPIO1_11 (LCD_D11);
LED4 -> GPIO1_10 (LCD_D10);
LED5 -> GPIO1_9 (LCD_D09);
I'm not sure if this is the correct way to change the mux in this kernel
version.
Some one know where I can find some informations or how to change this file?
Thanks for all help.

The only way to change it is making a board specific patch but it'd be
better to make a new dts file for your board.

Maybe a better mail list to get help on dts layout would be linux.org
Or you can create a new topic on imx-community.
It's completely kernel issue ;-)

you will find all the documentation here (and in your kernel source
tree) :
http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/tree/Documentation/devicetree
Starting from an existing i.MX28 based board can be a good idea.
check arch/arm/boot/dts/imx28*.dts
