From 033c9b96b260cb88199d5f802dda04a05d7dd3f8 Mon Sep 17 00:00:00 2001 From: Abhishek Sahu Date: Wed, 13 Dec 2017 19:55:40 +0530 Subject: [PATCH] clk: qcom: ipq8074: add GP and Crypto clocks - It has 3 general purpose clock controller which supplies the clock in GPIO pins. - It has Crypto Engine which has AXI, AHB and Core clocks. Other non APSS processors can also use Crypto Engine so these clocks are marked as VOTED clocks.
