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
