I suspect the hog groups are not getting initialized.
Please try:
&iomuxc { pinctrl-names = "default"; pinctrl-0 = <&pinctrl_hog>;
pinctrl_hog: hoggrp { fsl,pins = < ...... >;};
and then group all the hog pins under the same group.
Then check IOMUXC_SW_MUX_CTL_PAD to make sure the SION bit is set.
I decided to bypass the devicetree to test it on the imx8mq
static const iomux_v3_cfg_t configure_pads[] = { IMX8MQ_PAD_GPIO1_IO03__GPIO1_IO3 | MUX_PAD_CTRL(PAD_CTL_DSE6) | MUX_MODE_SION, IMX8MQ_PAD_GPIO1_IO14__GPIO1_IO14 | MUX_PAD_CTRL(PAD_CTL_DSE6) | MUX_MODE_SION, IMX8MQ_PAD_ENET_MDC__GPIO1_IO16 | MUX_PAD_CTRL(PAD_CTL_PUE) | MUX_MODE_SION, IMX8MQ_PAD_ENET_MDIO__GPIO1_IO17 | MUX_PAD_CTRL(PAD_CTL_PUE) | MUX_MODE_SION, };
static inline void init_pinmux(void) { imx_iomux_v3_setup_multiple_pads(configure_pads, ARRAY_SIZE(configure_pads)); }
And this works so I need to figure out what is wrong with my devicetree configuration.
Thanks Angus
