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 046/182] mmc: sdhci-msm: Qualcomm SDHCI binding documentation
+
+This patch adds the device-tree binding documentation for Qualcomm
+SDHCI driver. It contains the differences between the core properties
+in mmc.txt and the properties used by the sdhci-msm driver.

++* Qualcomm SDHCI controller (sdhci-msm)
++
++This file documents differences between the core properties in mmc.txt
++and the properties used by the sdhci-msm driver.
++
++Required properties:
++- compatible: Should contain "qcom,sdhci-msm-v4".
++- reg: Base address and length of the register in the following order:
++	- Host controller register map (required)
++	- SD Core register map (required)
++- interrupts: Should contain an interrupt-specifiers for the interrupts:
++	- Host controller interrupt (required)
++- pinctrl-names: Should contain only one value - "default".
++- pinctrl-0: Should specify pin control groups used for this controller.
++- clocks: A list of phandle + clock-specifier pairs for the clocks listed in clock-names.
++- clock-names: Should contain the following:
++	"iface" - Main peripheral bus clock (PCLK/HCLK - AHB Bus clock) (required)
++	"core"	- SDC MMC clock (MCLK) (required)
++	"bus"	- SDCC bus voter clock (optional)
++
++Example:
++
++	sdhc_1: sdhci@f9824900 {
++		compatible = "qcom,sdhci-msm-v4";
++		reg = <0xf9824900 0x11c>, <0xf9824000 0x800>;
++		interrupts = <0 123 0>;
++		bus-width = <8>;
++		non-removable;
++
++		vmmc = <&pm8941_l20>;
++		vqmmc = <&pm8941_s3>;
++
++		pinctrl-names = "default";
++		pinctrl-0 = <&sdc1_clk &sdc1_cmd &sdc1_data>;
++
++		clocks = <&gcc GCC_SDCC1_APPS_CLK>, <&gcc GCC_SDCC1_AHB_CLK>;
++		clock-names = "core", "iface";
++	};
++
++	sdhc_2: sdhci@f98a4900 {
++		compatible = "qcom,sdhci-msm-v4";
++		reg = <0xf98a4900 0x11c>, <0xf98a4000 0x800>;
++		interrupts = <0 125 0>;
++		bus-width = <4>;
++		cd-gpios = <&msmgpio 62 0x1>;
++
++		vmmc = <&pm8941_l21>;
++		vqmmc = <&pm8941_l13>;
++
++		pinctrl-names = "default";
++		pinctrl-0 = <&sdc2_clk &sdc2_cmd &sdc2_data>;
++
++		clocks = <&gcc GCC_SDCC2_APPS_CLK>, <&gcc GCC_SDCC2_AHB_CLK>;
++		clock-names = "core", "iface";
++	};
