This series is about the DW APB GPIO device initialization procedure cleaning up. First of all it has been discovered that having a vendor-specific "snps,nr-gpios" property isn't only redundant but also might be dangerous (see the commit log for details). Instead we suggest to use the generic "ngpios" property to define a number of GPIOs each DW APB GPIO controller port supports. Secondly seeing a tendency of the other GPIO drivers getting converted to using the GPIO-lib-based IRQ-chip interface this series provides a patch, which replaces the DW APB GPIO driver Generic IRQ-chip implementation with the GPIO-lib IRQ-chip one. Finally the DW APB GPIO device probe procedure is simplified by converting the code to be using the device managed resources for the reference clocks initialization, reset control assertion/de-assertion and GPIO-chip registration. Some additional cleanups like replacing a number of GPIOs literal with a corresponding macro and grouping the IRQ handlers up in a single place of the driver are also introduced in this patchset.
Sorry for the delay. Merge window and stress. All 10 patches applied for v5.10! Yours, Linus Walleij
