Hello list,

I try to set the following PAD in my imx6ul devicetree (derived from
imx6ul-14x14-evk.dts)

MX6UL_PAD_LCD_DATA10__GPIO3_IO15 0x100b0

but after kernel compiling and booting the register value is not
changed. A readout with devmem2 show me the wrong value.

devmem2 0x020E03CC
/dev/mem opened.
Memory mapped at address 0x76fc4000.
Read at address  0x020E03CC (0x76fc43cc): 0x000010B0

Setting the register manually with devmem2 just works fine.

/usr/bin/devmem2 0x020E03CC w 0x000100B0

other PADs like MX6UL_PAD_GPIO1_IO07__ENET1_MDC I could configure via
the imx6ul devicetree.

ideas what I'm doing wrong here?

Best Regards,

Oliver
