[PATCH 0/3] pinctrl: imx-scmi: Introdue nxp,iomuxc-daisy-off

["Peng Fan (OSS)" <peng.fan@oss.nxp.com>]

It might be a bit late, since it is 6.15-RC6 now. No rush, the target is 6.17.

i.MX9 SoC family IOMUXC features Daisy chain(multi pads driving same module
input pin), each SoC has its own daisy register offset. When add a new SoC
support, need to hardcode the register offset in pinctrl-imx-scmi.c just as
"
if (of_machine_is_compatible("fsl,imx95"))
   daisy_off = IMX95_DAISY_OFF;
else if
   ...
else
   ...
"

This is no good to long term maintainence.

With nxp,iomuxc-daisy-off introduced, things will be simplified to set
daisy register offset:
"device_property_read_u32(dev, "nxp,iomuxc-daisy-off", &pmx->daisy_off);"

The new property is set as required, so there might be dtbs_check error
without patch 3 applied. This is expected.

Patchset based on next-20250508
