Merge tag 'clk-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/clk/linux

Pull clk updates from Stephen Boyd:
 "This time we've got one core change to introduce a bulk clk_get API,
  some new clk drivers and updates for old ones. The diff is pretty
  spread out across a handful of different SoC clk drivers for Broadcom,
  TI, Qualcomm, Renesas, Rockchip, Samsung, and Allwinner, mostly due to
  the introduction of new drivers.

  Core:
   - New clk bulk get APIs
   - Clk divider APIs gained the ability to consider a different parent
     than the current one

  New Drivers:
   - Renesas r8a779{0,1,2,4} CPG/MSSR
   - TI Keystone SCI firmware controlled clks and OMAP4 clkctrl
   - Qualcomm IPQ8074 SoCs
   - Cortina Systems Gemini (SL3516/CS3516)
   - Rockchip rk3128 SoCs
   - Allwinner A83T clk control units
   - Broadcom Stingray SoCs
   - CPU clks for Mediatek MT8173/MT2701/MT7623 SoCs

  Removed Drivers:
   - Old non-DT version of the Realview clk driver

  Updates:
   - Renesas Kconfig/Makefile cleanups
   - Amlogic CEC EE clk support
   - Improved Armada 7K/8K cp110 clk support
   - Rockchip clk id exposing, critical clk markings
   - Samsung converted to clk_hw registration APIs
   - Fixes for Samsung exynos5420 audio clks
   - USB2 clks for Hisilicon hi3798cv200 SoC and video/camera clks for
     hi3660"

* Rockchip RK3128 Clock and Reset Unit
The RK3128 clock controller generates and supplies clock to various
controllers within the SoC and also implements a reset controller for SoC
peripherals.
Required Properties:
- compatible: should be "rockchip,rk3128-cru"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
- #reset-cells: should be 1.
Optional Properties:
- rockchip,grf: phandle to the syscon managing the "general register files"
If missing pll rates are not changeable, due to the missing pll lock status.
Each clock is assigned an identifier and client nodes can use this identifier
to specify the clock which they consume. All available clocks are defined as
preprocessor macros in the dt-bindings/clock/rk3128-cru.h headers and can be
used in device tree sources. Similar macros exist for the reset sources in
these files.
External clocks:
There are several clocks that are generated outside the SoC. It is expected
that they are defined using standard clock bindings with following
clock-output-names:
- "xin24m" - crystal input - required,
- "ext_i2s" - external I2S clock - optional,
- "gmac_clkin" - external GMAC clock - optional
Example: Clock controller node:
cru: cru@20000000 {
compatible = "rockchip,rk3128-cru";
reg = <0x20000000 0x1000>;
rockchip,grf = <&grf>;
#clock-cells = <1>;
#reset-cells = <1>;
};
Example: UART controller node that consumes the clock generated by the clock
controller:
uart2: serial@20068000 {
compatible = "rockchip,serial";
reg = <0x20068000 0x100>;
interrupts = <GIC_SPI 22 IRQ_TYPE_LEVEL_HIGH>;
clock-frequency = <24000000>;
clocks = <&cru SCLK_UART2>, <&cru PCLK_UART2>;
clock-names = "sclk_uart", "pclk_uart";

Texas Instruments TI-SCI Clocks
===============================
All clocks on Texas Instruments' SoCs that contain a System Controller,
are only controlled by this entity. Communication between a host processor
running an OS and the System Controller happens through a protocol known
as TI-SCI[1]. This clock implementation plugs into the common clock
framework and makes use of the TI-SCI protocol on clock API requests.
[1] Documentation/devicetree/bindings/arm/keystone/ti,sci.txt
Required properties:
-------------------
- compatible: Must be "ti,k2g-sci-clk"
- #clock-cells: Shall be 2.
In clock consumers, this cell represents the device ID and clock ID
exposed by the PM firmware. The assignments can be found in the header
files <dt-bindings/genpd/<soc>.h> (which covers the device IDs) and
<dt-bindings/clock/<soc>.h> (which covers the clock IDs), where <soc>
is the SoC involved, for example 'k2g'.
Examples:
--------
pmmc: pmmc {
compatible = "ti,k2g-sci";
k2g_clks: clocks {
compatible = "ti,k2g-sci-clk";
#clock-cells = <2>;
};
};
uart0: serial@2530c00 {
compatible = "ns16550a";

Texas Instruments clkctrl clock binding
Texas Instruments SoCs can have a clkctrl clock controller for each
interconnect target module. The clkctrl clock controller manages functional
and interface clocks for each module. Each clkctrl controller can also
gate one or more optional functional clocks for a module, and can have one
or more clock muxes. There is a clkctrl clock controller typically for each
interconnect target module on omap4 and later variants.
The clock consumers can specify the index of the clkctrl clock using
the hardware offset from the clkctrl instance register space. The optional
clocks can be specified by clkctrl hardware offset and the index of the
optional clock.
For more information, please see the Linux clock framework binding at
Documentation/devicetree/bindings/clock/clock-bindings.txt.
Required properties :
- compatible : shall be "ti,clkctrl"
- #clock-cells : shall contain 2 with the first entry being the instance
offset from the clock domain base and the second being the
clock index
Example: Clock controller node on omap 4430:
&cm2 {
l4per: cm@1400 {
cm_l4per@0 {
cm_l4per_clkctrl: clk@20 {
compatible = "ti,clkctrl";
reg = <0x20 0x1b0>;
#clock-cells = <2>;
};
};
};
};
Example: Preprocessor helper macros in dt-bindings/clock/ti-clkctrl.h
#define OMAP4_CLKCTRL_OFFSET 0x20
#define OMAP4_CLKCTRL_INDEX(offset) ((offset) - OMAP4_CLKCTRL_OFFSET)
#define MODULEMODE_HWCTRL 1
#define MODULEMODE_SWCTRL 2
#define OMAP4_GPTIMER10_CLKTRL OMAP4_CLKCTRL_INDEX(0x28)
#define OMAP4_GPTIMER11_CLKTRL OMAP4_CLKCTRL_INDEX(0x30)
#define OMAP4_GPTIMER2_CLKTRL OMAP4_CLKCTRL_INDEX(0x38)
...
#define OMAP4_GPIO2_CLKCTRL OMAP_CLKCTRL_INDEX(0x60)
Example: Clock consumer node for GPIO2:
&gpio2 {
clocks = <&cm_l4per_clkctrl OMAP4_GPIO2_CLKCTRL 0
&cm_l4per_clkctrl OMAP4_GPIO2_CLKCTRL 8>;
