imx7 GPIO pullup on pin used for special function

[eoin_oconnell]

Hi all,

I am using the following pins for the SIM functionality in my IMX7d.

1. pinctrl_sim1: sim-grp {
2. fsl,pins = <
3. MX7D_PAD_EPDC_DATA00__SIM1_PORT2_TRXD 0x30 /* SODIMM 111 5k pullup*/
4. MX7D_PAD_EPDC_DATA01__SIM1_PORT2_CLK 0x00 /* SODIMM 113*/
5. MX7D_PAD_EPDC_DATA02__SIM1_PORT2_RST_B 0x00 /* SODIMM 115*/
6. MX7D_PAD_EPDC_DATA03__SIM1_PORT2_SVEN 0x00 /* SODIMM 117*/
7. MX7D_PAD_EPDC_DATA04__SIM1_PORT2_PD 0x50 /* SODIMM 119 47k pull up*/
8. >;
9. };

I would like to know if even though the pin is being used for SIM special function if my 5k pull-up will still be activated? I do not have any option to put a pullup on my PCB, so this is my last resort
