Merge Linus master into drm-next

The merge is clean, but the arm build fails afterwards,
due to API changes in the regulator tree.

I've included the patch into the merge to fix the build.

 used by the sdhci-st driver.
 
 Required properties:
-- compatible :  Must be "st,sdhci"
-- clock-names : Should be "mmc"
-                See: Documentation/devicetree/bindings/resource-names.txt
-- clocks :      Phandle of the clock used by the sdhci controler
-                See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+- compatible:		Must be "st,sdhci" and it can be compatible to "st,sdhci-stih407"
+			to set the internal glue logic used for configuring the MMC
+			subsystem (mmcss) inside the FlashSS (available in STiH407 SoC
+			family).
+
+- clock-names:		Should be "mmc".
+			See: Documentation/devicetree/bindings/resource-names.txt
+- clocks:		Phandle to the clock.
+			See: Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+- interrupts:		One mmc interrupt should be described here.
+- interrupt-names:	Should be "mmcirq".
+
+- pinctrl-names:	A pinctrl state names "default" must be defined.
+- pinctrl-0:		Phandle referencing pin configuration of the sd/emmc controller.
+			See: Documentation/devicetree/bindings/pinctrl/pinctrl-binding.txt
+
+- reg:			This must provide the host controller base address and it can also
+			contain the FlashSS Top register for TX/RX delay used by the driver
+			to configure DLL inside the flashSS, if so reg-names must also be
+			specified.
 
 Optional properties:
-- non-removable: non-removable slot
-                 See: Documentation/devicetree/bindings/mmc/mmc.txt
-- bus-width: Number of data lines
-                 See: Documentation/devicetree/bindings/mmc/mmc.txt
+- reg-names:		Should be "mmc" and "top-mmc-delay". "top-mmc-delay" is optional
+			for eMMC on stih407 family silicon to configure DLL inside FlashSS.
+
+- non-removable:	Non-removable slot. Also used for configuring mmcss in STiH407 SoC
+			family.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- bus-width:		Number of data lines.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- max-frequency: 	Can be 200MHz, 100Mz or 50MHz (default) and used for
+			configuring the CCONFIG3 in the mmcss.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- resets:		Phandle and reset specifier pair to softreset line of HC IP.
+			See: Documentation/devicetree/bindings/reset/reset.txt
+
+- vqmmc-supply:		Phandle to the regulator dt node, mentioned as the vcc/vdd
+			supply in eMMC/SD specs.
+
+- sd-uhs--sdr50:	To enable the SDR50 in the mmcss.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- sd-uhs-sdr104:	To enable the SDR104 in the mmcss.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
+
+- sd-uhs-ddr50:		To enable the DDR50 in the mmcss.
+			See:  Documentation/devicetree/bindings/mmc/mmc.txt.
