From 20ec3e39fc12cf3a331ee73eb01d52bddcdd2fa4 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 11 Feb 2016 11:03:06 +0100 Subject: gpio: move the pin ranges into gpio_device Instead of keeping this reference to the pin ranges in the client driver-supplied gpio_chip, move it to the internal gpio_device as the drivers have no need to inspect this.
