Sim Module device tree

Hello All,

I am working on SIM module in IMX6, my pins are as shown below, some of the Pins I have used are from GPIO(highlighted) as I dont have pins left to be use from alternate SIM module pins.

sim1: sim@0218c000 {
compatible = "fsl,imx6ul-sim";
reg = <0x0218c000 0x4000>;
interrupts = <GIC_SPI 112 IRQ_TYPE_LEVEL_HIGH>;
status = "disabled";
};

pinctrl_sim1:sim1grp{
fsl,pins = <
MX6UL_PAD_CSI_DATA01__GPIO4_IO22 0x1B0B0 /* SVEN */
MX6UL_PAD_CSI_VSYNC__SIM1_PORT1_CLK 0x1B0B0 /* CLK */
MX6UL_PAD_CSI_DATA00__SIM1_PORT1_RST_B 0x1B0B0 /* RST_B*/
MX6UL_PAD_CSI_DATA02__SIM1_PORT1_TRXD 0x1B0B0 /* IO */
MX6UL_PAD_CSI_HSYNC__GPIO4_IO20 0x1B0B0 /* PD */
MX6UL_PAD_SD1_CMD__GPIO2_IO16 0x1B0B0 /* 5V3V */
>;
};

&sim1 {
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_sim1>;
status = "okay";
};

My question is, will sim driver take care of these GPIO pins as well, or I will have to take care of them individually?

Regards,

Asma

Hi Asma

sim dts example can be found on

linux/arch/arm/boot/dts/imx6ul-14x14-evk.dts

imx6ul-14x14-evk.dts\dts\boot\arm\arch - linux-imx - i.MX Linux kernel

sim driver description in Linux L4.14.98_2.0.0 Documentation

I am afraid gpio signals can not be used as sim signals.

Best regards
igor
