Hi,
We are using imx6Q sabresd platform for our development with Linux
3.10.17_1.0.0-GA BSP.
In device tree, the UART1 IOMUX configuration is done in
"arch/arm/boot/dts/imx6qdl.dtsi" file as mentioned below.
uart1 {
pinctrl_uart1_1: uart1grp-1 {
fsl,pins = <
MX6QDL_PAD_CSI0_DAT10__UART1_TX_DATA 0x1b0b1
MX6QDL_PAD_CSI0_DAT11__UART1_RX_DATA 0x1b0b1
;
};
};
We would like to know, in which file the IOMUX configuration will be called?
We have gone through the "linux-imx/drivers/tty/serial/imx.c" file. But
we couldn't find the below function for IOMUX configuration
"devm_pinctrl_get_select_default"
In addition, the flexcan IOMUX configuration is called in
"drivers/net/can/flexcan.c" file as mentioned below (from the probe
function call)
pinctrl = devm_pinctrl_get_select_default(&pdev->dev);
if (IS_ERR(pinctrl))
return PTR_ERR(pinctrl);
Please suggest us for better understanding.
Thank You,
Regards,
Ansari
