imx6 remapping uart question

[aaronpadilla]

I am remapping the uart1 and uart5 but there are a hex number after the pin name, I could not find what it is for:

&iomuxc {
imx6qdl-scm {
/* add MUXing entry for SD2 4-bit interface and configure control pins */
pinctrl_uart2_my: uart2grp {
fsl,pins = <
MX6QDL_PAD_EIM_D26__UART2_TX_DATA 0x1f0b1
MX6QDL_PAD_EIM_D27__UART2_RX_DATA 0x1f0b1
>;
};

/*remapping uart1 for GPS*/
pinctrl_uart1_my: uart1grp {
fsl,pins = <
MX6QDL_PAD_CSI0_DAT10__UART1_TX_DATA 0x1b0b1
MX6QDL_PAD_CSI0_DAT11__UART1_RX_DATA 0x1b0b1
>;
};

};
};

what is it? 0x1f0b1  0x1b0b1

Colud you advice?

Hi Aaron,

In the IOMUX chapter of reference Manual you can find followng registers:

IOMUXC_SW_PAD_CTL_PAD_EIM_DATA26

IOMUXC_SW_MUX_CTL_PAD_EIM_DATA26

The number you are asking for is the value of register IOMUXC_SW_PAD_CTL_PAD_EIM_DATA26 while the name of the mcro is related to MUX function which is associated to IOMUXC_SW_MUX_CTL_PAD_EIM_DATA26.

Regards,
Carlos
