From 18dbb7b335c2b4d14f2d72d77bdd60c6e5ebd25f Mon Sep 17 00:00:00 2001 From: Sean Anderson Date: Mon, 14 Sep 2020 11:02:00 -0400 Subject: gpio: dw: Add a trailing underscore to generated name Previously, if there was no bank-name property, it was easy to have confusing gpio names like "gpio1@08", instead of "gpio1@0_8". This patch follows the example of the sifive gpio driver.
