Subject[PATCH 0/7] gpio: dwapb: Refactor GPIO resources initialization
Date
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.
