+* 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>,

- *
- * Most of the work is done in the chip specific module, 53c700.o

- * TODO List:
- *
- * 1. Extract the SCSI ID from the voyager CMOS table (necessary to
- * support multi-host environments.
- *
- * */
-
-
-/* CHANGELOG
- *
- * Version 2.2
- *
- * Added mca_set_adapter_name().
- *
- * Version 2.1
- *
- * Modularise the driver into a Board piece (this file) and a chip
- * piece 53c700.[ch] and 53c700.scr, added module options. You can
- * now specify the scsi id by the parameters
- *
- * NCR_D700=slot:<n> [siop:<n>] id:<n> ....
- *
- * They need to be comma separated if compiled into the kernel
- *
- * Version 2.0
- *
- * Initial implementation of TCQ (Tag Command Queueing). TCQ is full
- * featured and uses the clock algorithm to keep track of outstanding
- * tags and guard against individual tag starvation. Also fixed a bug
- * in all of the 1.x versions where the D700_data_residue() function
- * was returning results off by 32 bytes (and thus causing the same 32
- * bytes to be written twice corrupting the data block). It turns out
- * the 53c700 only has a 6 bit DBC and DFIFO registers not 7 bit ones
- * like the 53c710 (The 710 is the only data manual still available,
- * which I'd been using to program the 700).
- *
- * Version 1.2
- *
- * Much improved message handling engine
- *
- * Version 1.1
- *
- * Add code to handle selection reasonably correctly. By the time we
- * get the selection interrupt, we've already responded, but drop off the
- * bus and hope the selector will go away.
- *
- * Version 1.0:
- *
- * Initial release. Fully functional except for procfs and tag
- * command queueing. Has only been tested on cards with 53c700-66
- * chips and only single ended. Features are
- *
- * 1. Synchronous data transfers to offset 8 (limit of 700-66) and
- * 100ns (10MHz) limit of SCSI-2
- *
- * 2. Disconnection and reselection
- *
- * Testing:
- *
- * I've only really tested this with the 700-66 chip, but have done
- * soak tests in multi-device environments to verify that
- * disconnections and reselections are being processed correctly.
