From 9a9b5a4af066f1245d7848a5d5d5c8147c18aa28 Mon Sep 17 00:00:00 2001 From: Stephen Boyd <sboyd@kernel.org> Date: Fri, 30 Aug 2019 08:09:12 -0700 Subject: clk: gpio: Use DT way of specifying parents Nobody has used the gpio clk registration functions nor the gpio clk_ops exposed by the basic gpio clk type. Let's remove all those APIs and move the gpio clk support into the C file. Since nothing is using the exported APIs, simplify the driver to be a platform driver that uses clk_parent_data to pick 0th or 1st cell of the node's clocks property.
