During the review of my MT8365 support patchset (https://lore.kernel.org/linux-mediatek/20221117210356.3178578-1-bero@xxxxxxxxxxxx/), the issue of the "pins-are-numbered" DeviceTree property has come up. This property is unique to Mediatek MT65xx and STM32 pinctrls, and doesn't seem to serve any purpose (both the Mediatek and STM32 drivers simply refuse to deal with a device unless pins-are-numbered is set to true). There is no other use of this property in the kernel or in other projects using DeviceTrees (checked u-boot and FreeBSD -- in both of those, the flag is present in Mediatek and STM devicetrees, but not used anywhere). There is also no known use in userspace (in fact, a userland application relying on the property would be broken because it would get true on any Mediatek or STM chipset and false on all others, even though other chipsets use numbered pins). This patchset removes all uses of pins-are-numbered.
