Not sure I understand the proposal. Can you provide couple of (simplest) examples? And also it sounds like reinventing a wheel. What problem do you have that you need to solve this way?Have you seen these: drivers/gpio/gpio-dwapb.c drivers/mfd/intel_quark_i2c_gpio.c ? GPIO driver has a main (controller level) node along with children on per bank basis. Currently it works with the provided approach (see second driver).
Btw, may be helpful to debug swnodes application https://lore.kernel.org/lkml/20210327222012.54103-3-andriy.shevchenko@linux.intel.com/#t (local) -- With Best Regards, Andy Shevchenko
