-From 6e0d50daa97f4bf9706e343b4f71171e88921209 Mon Sep 17 00:00:00 2001
-From: Maxime Ripard <maxime.ripard@free-electrons.com>
-Date: Thu, 29 Sep 2016 22:57:26 +0200
-Subject: clk: sunxi-ng: Add minimums for all the relevant structures and
- clocks
-
-Modify the current clocks we have to be able to specify the minimum for
-each clocks we support, just like we support the max.
