Merge branch 'late/clksrc' into late/cleanup
There is no reason to keep the clksrc cleanups separate from the other cleanups, and this resolves some merge conflicts. Conflicts: arch/arm/mach-spear/spear13xx.c drivers/irqchip/Makefile

+Frequently asked questions about the sunxi clock system
+=======================================================
+
+This document contains useful bits of information that people tend to ask
+about the sunxi clock system, as well as accompanying ASCII art when adequate.
+
+Q: Why is the main 24MHz oscillator gatable? Wouldn't that break the
+ system?
+
+A: The 24MHz oscillator allows gating to save power. Indeed, if gated
+ carelessly the system would stop functioning, but with the right
+ steps, one can gate it and keep the system running. Consider this
+ simplified suspend example:
+
+ While the system is operational, you would see something like
+
+ 24MHz 32kHz
+ |
+ PLL1
+ \
+ \_ CPU Mux
+ |
+ [CPU]
+
+ When you are about to suspend, you switch the CPU Mux to the 32kHz
+ oscillator:
+
+ 24Mhz 32kHz
+ | |
+ PLL1 |
+ /
+ CPU Mux _/
+ |
+ [CPU]
+
+ Finally you can gate the main oscillator
+
+ 32kHz
+ |
+ |
+ /
+ CPU Mux _/
+ |
+ [CPU]
+
+Q: Were can I learn more about the sunxi clocks?
+
+A: The linux-sunxi wiki contains a page documenting the clock registers,
+ you can find it at
+
+ http://linux-sunxi.org/A10/CCM
+
+ The authoritative source for information at this time is the ccmu driver
+ released by Allwinner, you can find it at
+
+ https://github.com/linux-sunxi/linux-sunxi/tree/sunxi-3.0/arch/arm/mach-sun4i/clock/ccmu

NVIDIA Tegra Power Management Controller (PMC)
-Properties:
+The PMC block interacts with an external Power Management Unit. The PMC
+mostly controls the entry and exit of the system from different sleep
+modes. It provides power-gating controllers for SoC and CPU power-islands.
+
+Required properties:
- name : Should be pmc
- compatible : Should contain "nvidia,tegra<chip>-pmc".
- reg : Offset and length of the register set for the device
+- clocks : Must contain an entry for each entry in clock-names.
+- clock-names : Must include the following entries:
+ "pclk" (The Tegra clock of that name),
+ "clk32k_in" (The 32KHz clock input to Tegra).
+
+Optional properties:
- nvidia,invert-interrupt : If present, inverts the PMU interrupt signal.
The PMU is an external Power Management Unit, whose interrupt output
signal is fed into the PMC. This signal is optionally inverted, and then
fed into the ARM GIC. The PMC is not involved in the detection or
handling of this interrupt signal, merely its inversion.
+- nvidia,suspend-mode : The suspend mode that the platform should use.
+ Valid values are 0, 1 and 2:
+ 0 (LP0): CPU + Core voltage off and DRAM in self-refresh
+ 1 (LP1): CPU voltage off and DRAM in self-refresh
+ 2 (LP2): CPU voltage off
+- nvidia,core-power-req-active-high : Boolean, core power request active-high
+- nvidia,sys-clock-req-active-high : Boolean, system clock request active-high
+- nvidia,combined-power-req : Boolean, combined power request for CPU & Core
+- nvidia,cpu-pwr-good-en : Boolean, CPU power good signal (from PMIC to PMC)
+ is enabled.
+
+Required properties when nvidia,suspend-mode is specified:
+- nvidia,cpu-pwr-good-time : CPU power good time in uS.
+- nvidia,cpu-pwr-off-time : CPU power off time in uS.
+- nvidia,core-pwr-good-time : <Oscillator-stable-time Power-stable-time>
+ Core power good time in uS.
+- nvidia,core-pwr-off-time : Core power off time in uS.
+
+Required properties when nvidia,suspend-mode=<0>:
+- nvidia,lp0-vec : <start length> Starting address and length of LP0 vector
+ The LP0 vector contains the warm boot code that is executed by AVP when
+ resuming from the LP0 state. The AVP (Audio-Video Processor) is an ARM7
+ processor and always being the first boot processor when chip is power on
+ or resume from deep sleep mode. When the system is resumed from the deep
+ sleep mode, the warm boot code will restore some PLLs, clocks and then
+ bring up CPU0 for resuming the system.

+NVIDIA Tegra114 Clock And Reset Controller
+
+This binding uses the common clock binding:
+Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+The CAR (Clock And Reset) Controller on Tegra is the HW module responsible
+for muxing and gating Tegra's clocks, and setting their rates.
+
+Required properties :
+- compatible : Should be "nvidia,tegra114-car"
+- reg : Should contain CAR registers location and length
+- clocks : Should contain phandle and clock specifiers for two clocks:
+ the 32 KHz "32k_in", and the board-specific oscillator "osc".
+- #clock-cells : Should be 1.
+ In clock consumers, this cell represents the clock ID exposed by the CAR.
+
+ The first 160 clocks are numbered to match the bits in the CAR's CLK_OUT_ENB
+ registers. These IDs often match those in the CAR's RST_DEVICES registers,
+ but not in all cases. Some bits in CLK_OUT_ENB affect multiple clocks. In
+ this case, those clocks are assigned IDs above 160 in order to highlight
+ this issue. Implementations that interpret these clock IDs as bit values
+ within the CLK_OUT_ENB or RST_DEVICES registers should be careful to
+ explicitly handle these special cases.
+
+ The balance of the clocks controlled by the CAR are assigned IDs of 160 and
+ above.

+Device tree bindings for Ethernet chip connected to TI GPMC
+
+Besides being used to interface with external memory devices, the
+General-Purpose Memory Controller can be used to connect Pseudo-SRAM devices
+such as ethernet controllers to processors using the TI GPMC as a data bus.
+
+Ethernet controllers connected to TI GPMC are represented as child nodes of
+the GPMC controller with an "ethernet" name.
+
+All timing relevant properties as well as generic GPMC child properties are
+explained in a separate documents. Please refer to
+Documentation/devicetree/bindings/bus/ti-gpmc.txt
+
+For the properties relevant to the ethernet controller connected to the GPMC
+refer to the binding documentation of the device. For example, the documentation
+for the SMSC 911x is Documentation/devicetree/bindings/net/smsc911x.txt
+
+Child nodes need to specify the GPMC bus address width using the "bank-width"
+property but is possible that an ethernet controller also has a property to
+specify the I/O registers address width. Even when the GPMC has a maximum 16-bit
+address width, it supports devices with 32-bit word registers.
+For example with an SMSC LAN911x/912x controller connected to the TI GPMC on an
+OMAP2+ board, "bank-width = <2>;" and "reg-io-width = <4>;".
+
+Required properties:
+- bank-width: Address width of the device in bytes. GPMC supports 8-bit
+ and 16-bit devices and so must be either 1 or 2 bytes.
+- compatible: Compatible string property for the ethernet child device.

+
+Please refer to pinctrl-bindings.txt in this directory for details of the

+
+Each pin configuration node lists the pin(s) to which it applies, and one or

+configuration. Each subnode only affects those parameters that are explicitly

+a pull parameter implies no information about the mux function.

+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):

+Samsung's Multi Core Timer (MCT)
+
+The Samsung's Multi Core Timer (MCT) module includes two main blocks, the
+global timer and CPU local timers. The global timer is a 64-bit free running
+up-counter and can generate 4 interrupts when the counter reaches one of the
+four preset counter values. The CPU local timers are 32-bit free running
+down-counters and generate an interrupt when the counter expires. There is
+one CPU local timer instantiated in MCT for every CPU in the system.
+
+Required properties:
+
+- compatible: should be "samsung,exynos4210-mct".
+ (a) "samsung,exynos4210-mct", for mct compatible with Exynos4210 mct.
+ (b) "samsung,exynos4412-mct", for mct compatible with Exynos4412 mct.
+
+- reg: base address of the mct controller and length of the address space
+ it occupies.
+
+- interrupts: the list of interrupts generated by the controller. The following
+ should be the order of the interrupts specified. The local timer interrupts
+ should be specified after the four global timer interrupts have been
+ specified.
+
+ 0: Global Timer Interrupt 0

+ 3: Global Timer Interrupt 3
+ 4: Local Timer Interrupt 0
+ 5: Local Timer Interrupt 1
+ 6: ..
+ 7: ..
+ i: Local Timer Interrupt n
