Merge tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi 

Pull SCSI updates from James Bottomley:
 "This is mostly updates to the usual drivers: mpt3sas, lpfc, qla2xxx,
  hisi_sas, smartpqi, megaraid_sas, arcmsr.

  In addition, with the continuing absence of Nic we have target updates
  for tcmu and target core (all with reviews and acks).

  The biggest observable change is going to be that we're (again) trying
  to switch to mulitqueue as the default (a user can still override the
  setting on the kernel command line).

  Other major core stuff is the removal of the remaining Microchannel
  drivers, an update of the internal timers and some reworks of
  completion and result handling"

* Hisilicon Universal Flash Storage (UFS) Host Controller



UFS nodes are defined to describe on-chip UFS hardware macro.

Each UFS Host Controller should have its own node.



Required properties:

- compatible        : compatible list, contains one of the following -

					"hisilicon,hi3660-ufs", "jedec,ufs-1.1" for hisi ufs

					host controller present on Hi36xx chipset.

- reg               : should contain UFS register address space & UFS SYS CTRL register address,

- interrupt-parent  : interrupt device

- interrupts        : interrupt number

- clocks	        : List of phandle and clock specifier pairs

- clock-names       : List of clock input name strings sorted in the same

					order as the clocks property. "ref_clk", "phy_clk" is optional

- freq-table-hz     : Array of <min max> operating frequencies stored in the same

                      order as the clocks property. If this property is not

                      defined or a value in the array is "0" then it is assumed

                      that the frequency is set by the parent clock or a

                      fixed rate clock source.

- resets            : describe reset node register

- reset-names       : reset node register, the "rst" corresponds to reset the whole UFS IP.



Example:



	ufs: ufs@ff3b0000 {

		compatible = "hisilicon,hi3660-ufs", "jedec,ufs-1.1";

		/* 0: HCI standard */

		/* 1: UFS SYS CTRL */

		reg = <0x0 0xff3b0000 0x0 0x1000>,

			<0x0 0xff3b1000 0x0 0x1000>;

		interrupt-parent = <&gic>;

		interrupts = <GIC_SPI 278 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&crg_ctrl HI3660_CLK_GATE_UFSIO_REF>,

			<&crg_ctrl HI3660_CLK_GATE_UFSPHY_CFG>;

		clock-names = "ref_clk", "phy_clk";

		freq-table-hz = <0 0>, <0 0>;

		/* offset: 0x84; bit: 12  */

		resets = <&crg_rst 0x84 12>;

		reset-names = "rst";

	};
