From mboxrd@z Thu Jan 1 00:00:00 1970 From: David Lechner Subject: [PATCH] gpio: davinci: add support for pinmux gpio ranges Date: Sun, 21 Jan 2018 17:09:40 -0600 Message-ID: <1516576180-1467-1-git-send-email-david@lechnology.com> Return-path: Sender: linux-kernel-owner@vger.kernel.org To: linux-gpio@vger.kernel.org Cc: David Lechner , linux-arm-kernel@lists.infradead.org, linux-kernel@vger.kernel.org, Keerthy , Linus Walleij List-Id: linux-gpio@vger.kernel.org This adds support for the pinmux gpio ranges feature to the DaVinci gpio driver. Only device tree is supported since the non-DT boards don't use a generic pinmux controller.
