Merge tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc
Pull ARM SoC platform changes from Olof Johansson: "This is the bulk of new SoC enablement and other platform changes for 3.17: - Samsung S5PV210 has been converted to DT and multiplatform - Clock drivers and bindings for some of the lower-end i.MX 1/2 platforms - Kirkwood, one of the popular Marvell platforms, is folded into the mvebu platform code, removing mach-kirkwood - Hwmod data for TI AM43xx and DRA7 platforms - More additions of Renesas shmobile platform support - Removal of plat-samsung contents that can be removed with S5PV210 being multiplatform/DT-enabled and the other two old platforms being removed New platforms (most with only basic support right now): - Hisilicon X5HD2 settop box chipset is introduced - Mediatek MT6589 (mobile chipset) is introduced - Broadcom BCM7xxx settop box chipset is introduced + as usual a lot other pieces all over the platform code" * tag 'soc-for-3.17' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (240 commits) ARM: hisi: remove smp from machine descriptor power: reset: move hisilicon reboot code ARM: dts: Add hix5hd2-dkb dts file.

+* Samsung Audio Subsystem Clock Controller
+
+The Samsung Audio Subsystem clock controller generates and supplies clocks
+to Audio Subsystem block available in the S5PV210 and compatible SoCs.
+
+Required Properties:
+
+- compatible: should be "samsung,s5pv210-audss-clock".
+- reg: physical base address and length of the controller's register set.
+
+- #clock-cells: should be 1.
+
+- clocks:
+ - hclk: AHB bus clock of the Audio Subsystem.
+ - xxti: Optional fixed rate PLL reference clock, parent of mout_audss. If
+ not specified (i.e. xusbxti is used for PLL reference), it is fixed to
+ a clock named "xxti".
+ - fout_epll: Input PLL to the AudioSS block, parent of mout_audss.
+ - iiscdclk0: Optional external i2s clock, parent of mout_i2s. If not
+ specified, it is fixed to a clock named "iiscdclk0".
+ - sclk_audio0: Audio bus clock, parent of mout_i2s.
+
+- clock-names: Aliases for the above clocks. They should be "hclk",
+ "xxti", "fout_epll", "iiscdclk0", and "sclk_audio0" respectively.
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/s5pv210-audss-clk.h header and can be used in device
+tree sources.
+
+Example: Clock controller node.
+
+ clk_audss: clock-controller@c0900000 {
+ compatible = "samsung,s5pv210-audss-clock";
+ reg = <0xc0900000 0x1000>;
+ #clock-cells = <1>;
+ clock-names = "hclk", "xxti",
+ "fout_epll", "sclk_audio0";
+ clocks = <&clocks DOUT_HCLKP>, <&xxti>,
+ <&clocks FOUT_EPLL>, <&clocks SCLK_AUDIO0>;
+ };
+
+Example: I2S controller node that consumes the clock generated by the clock
+ controller. Refer to the standard clock bindings for information
+ about 'clocks' and 'clock-names' property.
+
+ i2s0: i2s@03830000 {
+ /* ... */
+ clock-names = "iis", "i2s_opclk0",
+ "i2s_opclk1";
+ clocks = <&clk_audss CLK_I2S>, <&clk_audss CLK_I2S>,
+ <&clk_audss CLK_DOUT_AUD_BUS>;
+ /* ... */
+ };
