-- cgit v1.2.2 From 1fb2e4aab8b31b15e6be5debacb4203333360fd2 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Thu, 25 Jul 2013 21:06:56 +0200 Subject: clk: sunxi: Add Allwinner A20 gates MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit The Allwinner A20 is almost identical to the earlier A10 SoC from Allwinner on many aspects, including the clocks tree. However, since the A20 has some additionnal IPs compared to the A10, the clock tree isn't exactly the same, especially when it comes to the gated clocks available. We thus need to register different clock gates for the A20.
