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

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.

Samsung S3C24XX Interrupt Controllers
|
||||
|
||||
The S3C24XX SoCs contain a custom set of interrupt controllers providing a
|
||||
varying number of interrupt sources. The set consists of a main- and sub-
|
||||
controller and on newer SoCs even a second main controller.
|
||||
|
||||
Required properties:
|
||||
- compatible: Compatible property value should be "samsung,s3c2410-irq"
|
||||
for machines before s3c2416 and "samsung,s3c2416-irq" for s3c2416 and later.
|
||||
|
||||
- reg: Physical base address of the controller and length of memory mapped
|
||||
region.
|
||||
|
||||
- interrupt-controller : Identifies the node as an interrupt controller
|
||||
|
||||
- #interrupt-cells : Specifies the number of cells needed to encode an
|
||||
interrupt source. The value shall be 4 and interrupt descriptor shall
|
||||
have the following format:
|
||||
<ctrl_num parent_irq ctrl_irq type>
|
||||
|
||||
ctrl_num contains the controller to use:
|
||||
- 0 ... main controller
|
||||
- 1 ... sub controller
|
||||
- 2 ... second main controller on s3c2416 and s3c2450
|

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.
|
||||
- gpmc,cs-on: Chip-select assertion time
|
||||
- gpmc,cs-rd-off: Chip-select de-assertion time for reads
|
||||
- gpmc,cs-wr-off: Chip-select de-assertion time for writes
|
||||
- gpmc,oe-on: Output-enable assertion time
|
||||
- gpmc,oe-off Output-enable de-assertion time
|
||||
- gpmc,we-on: Write-enable assertion time
|
||||
- gpmc,we-off: Write-enable de-assertion time
|
||||
- gpmc,access: Start cycle to first data capture (read access)
|
||||
- gpmc,rd-cycle: Total read cycle time
|
||||
- gpmc,wr-cycle: Total write cycle time
|
||||
- reg: Chip-select, base address (relative to chip-select)
|
||||
and size of the memory mapped for the device.
|
||||
Note that base address will be typically 0 as this
|
||||
is the start of the chip-select.
|

VIA VT8500 and Wondermedia WM8xxx-series pinmux/gpio controller
|
||||
|
||||
These SoCs contain a combined Pinmux/GPIO module. Each pin may operate as
|
||||
either a GPIO in, GPIO out or as an alternate function (I2C, SPI etc).
|
||||
|
||||
Required properties:
|
||||
- compatible: "via,vt8500-pinctrl", "wm,wm8505-pinctrl", "wm,wm8650-pinctrl",
|
||||
"wm8750-pinctrl" or "wm,wm8850-pinctrl"
|
||||
- reg: Should contain the physical address of the module's registers.
|
||||
- interrupt-controller: Marks the device node as an interrupt controller.
|
||||
- #interrupt-cells: Should be two.
|
||||
- gpio-controller: Marks the device node as a GPIO controller.
|
||||
- #gpio-cells : Should be two. The first cell is the pin number and the
|
||||
second cell is used to specify optional parameters.
|
||||
bit 0 - active low
|
||||
|
||||
Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
|
||||
|
||||
Please refer to pinctrl-bindings.txt in this directory for details of the
|
||||
common pinctrl bindings used by client devices, including the meaning of the
|
||||
phrase "pin configuration node".
|
||||
|
||||
Each pin configuration node lists the pin(s) to which it applies, and one or
|
||||
more of the mux functions to select on those pin(s), and pull-up/down
|
||||
configuration. Each subnode only affects those parameters that are explicitly
|
||||
listed. In other words, a subnode that lists only a mux function implies no
|
||||
information about any pull configuration. Similarly, a subnode that lists only
|
||||
a pull parameter implies no information about the mux function.
|
||||
|
||||
Required subnode-properties:
|
||||
- wm,pins: An array of cells. Each cell contains the ID of a pin.
|
||||
|
||||
Optional subnode-properties:
|
||||
- wm,function: Integer, containing the function to mux to the pin(s):
|
||||
0: GPIO in
|
||||
1: GPIO out
|
||||
2: alternate
|
||||
|
||||
- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):
|
||||
0: none
|
||||
1: down
|
||||
2: up
|
||||
|
||||
Each of wm,function and wm,pull may contain either a single value which
|
||||
will be applied to all pins in wm,pins, or one value for each entry in
|
||||
wm,pins.
|
||||
|
||||
Example:
|
||||
|
||||
pinctrl: pinctrl {
|
||||
compatible = "wm,wm8505-pinctrl";
|
||||
reg = <0xD8110000 0x10000>;

|
||||
#interrupt-cells = <2>;

ARM sp804 Dual Timers
|

|
||||
Required properties:
|

- compatible: Should be "arm,sp804" & "arm,primecell"
|
||||
- interrupts: Should contain the list of Dual Timer interrupts. This is the
|

interrupt for timer 1 and timer 2. In the case of a single entry, it is
|
||||
the combined interrupt or if "arm,sp804-has-irq" is present that
|
||||
specifies which timer interrupt is connected.
|
||||
- reg: Should contain location and length for dual timer register.
|
||||
- clocks: clocks driving the dual timer hardware. This list should be 1 or 3
|
||||
clocks. With 3 clocks, the order is timer0 clock, timer1 clock,
|
||||
apb_pclk. A single clock can also be specified if the same clock is
|
||||
used for all clock inputs.
|
||||
|
||||
Optional properties:
|
||||
- arm,sp804-has-irq = <#>: In the case of only 1 timer irq line connected, this
|
||||
specifies if the irq connection is for timer 1 or timer 2. A value of 1
|
||||
or 2 should be used.

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
|
||||
1: Global Timer Interrupt 1
|
||||
2: Global Timer Interrupt 2
|
||||
3: Global Timer Interrupt 3
|
||||
4: Local Timer Interrupt 0
|
||||
5: Local Timer Interrupt 1
|
||||
6: ..
|
||||
7: ..
|
||||
i: Local Timer Interrupt n
|
||||
|
||||
Example 1: In this example, the system uses only the first global timer
|
||||
interrupt generated by MCT and the remaining three global timer
|
||||
interrupts are unused. Two local timer interrupts have been
|
||||
specified.
|
||||
|
||||
mct@10050000 {
|
||||

|
||||
<0 42 0>, <0 48 0>;
|
||||
};
|
||||
|
||||
Example 2: In this example, the MCT global and local timer interrupts are
|
||||
connected to two seperate interrupt controllers. Hence, an
|
||||
interrupt-map is created to map the interrupts to the respective
|
||||
interrupt controllers.
