Subject: [PATCH v2 09/11] 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.
