From 65bccc432d1f2877a92b7341cbb08b8ef9e0d09d Mon Sep 17 00:00:00 2001
From: Martin Sperl <kernel@martin.sperl.org>
Date: Mon, 29 Feb 2016 15:43:57 +0000
Subject: [PATCH] clk: bcm2835: add missing osc and per clocks
Add AVE0, DFT, GP0, GP1, GP2, SLIM, SMI, TEC, DPI, CAM0, CAM1, DSI0E,
and DSI1E. PULSE is not added because it has an extra divider.
Signed-off-by: Martin Sperl <kernel@martin.sperl.org>

(cherry picked from commit d3d6f15fd376e3dbba851724057b112558c70b79)
