I'm looking at porting zephyr to the cortex m4 and I'm starting to come up against a few problems with generating the device tree files using the nxp/mcux/scripts/pinctrl/imx/imx_gen_{dts,gpio,headers}.py scripts.
I've modified the scripts as showing the diff file
This does the following:
a) generates what looks to be correct mcimx7u5xxxxx-pinctrl.dtsi files
b) doesn't generated anything usefullfor the mcimx7u5xxxxx-gpio.dtsi files
c) incorrectly generates the pinctrl groups names for the file mcimx7ulp_evk_rev_b-pinctrl.dtsi
I've run the imx_fixup_pinmux.py on both the pinctrl files but this hasn't fixed them.
So I think that the problem is with the "SignalPin" in "imx_cfg_utils.py" as I'm incorrectly allowing "SW_PAD_CTL_PAD_" to be a signal pin and that I haven't modified the "IOMUXOption" to flag the "pta1_port_pta1", etc as GPIO's.
Any help would be greatly appreciated.
Chris
