"pinctrl-single,gpio-range" allows us to define a dis-contiguous range of pinctrl registers that can have different mux settings for GPIO mode of operation. However, the maxItems seem to be set to 1 in processed schema for some reason. This is incorrect. For example: arch/arm64/boot/dts/hisilicon/hi6220.dtsi and others have more than one dis-contiguous range. Arbitrarily define a max 100 count to override the defaults. Signed-off-by: Nishanth Menon <nm@xxxxxx> --- I am not sure if I should call this RFC or not.. and if this is even the right solution.. I am on 2024.05 dt-schema for this check. I noticed this when adding gpio-ranges for am62p platform: https://gist.github.com/nmenon/7019cd2f24be47997640df5db60a7544 It is possible that this is a bug in dt-schema, but I have'nt been able to track it down either. behavior seen is the following: pinctrl-single,gpio-range = <&mcu_pmx_range 0 21 7>; generates no warning However, pinctrl-single,gpio-range = <&mcu_pmx_range 0 21 7>, <&mcu_pmx_range 32 2 7>; generates "is too long" warning.
