From 32d9617234f53d7fef18ec94d9bcfc805bb9df16 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Mon, 13 Mar 2017 00:28:13 +0100 Subject: gpio: gemini: augment DT bindings The DT bindings assumed that this IP block was coming from Cortina Systems, which turns out not to be true. It is a standard IP block from Faraday Technology and also used in the Moxa moxart SoC. We augment the bindings to cover all existing parts and rename it after the IP block. This involves deleting the old Moxa bindings that now are contained in this binding.
