ipq806x: Add support for IPQ806x chip family
Patches are generated using the "format-patch" command from the following location: *https://www.codeaurora.org/cgit/quic/kernel/galak-msm/log/?h=apq_ipq_base *rev=0771849495b4128cac2faf7d49c85c729fc48b20 Patches numbered 76/77/102/103 have already been integrated in 3.14.12, so they're not in this list. All these patches are either integrated are pending integration into kernel.org, therefore these patches should go away once the kernel gets upgraded to 3.16. Support is currently limited to AP148 board but can be extended to other platforms in the future. These changes do not cover ethernet connectivity.

+Subject: [PATCH 107/182] clk: qcom: Support msm8974pro global clock control
+ hardware
+
+A new PLL (gpll4) is added on msm8974 PRO devices to support a
+faster sdc1 clock rate. Add support for this and the two new sdcc
+cal clocks.
