From d97a1b5688b015d94d0365b032c0659957a9e9d1 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Fri, 20 Oct 2017 12:26:51 +0200 Subject: gpio: dwapb: fix bgpio usage The DW APB GPIO driver uses the generic GPIO library gpio-mmio, and initialize the flags as "false", which should be 0. When no flags are given, the native endianness is used to access the MMIO registers, and the pin2mask() call can simply be converted to a BIT() call, as per the default pin2mask() implementation in gpio-mmio.c.
