+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

Below is a matrix detailing which clk_ops are mandatory based upon the
-hardware capbilities of that clock. A cell marked as "y" means
+hardware capabilities of that clock. A cell marked as "y" means
mandatory, a cell marked as "n" implies that either including that
-callback is invalid or otherwise uneccesary. Empty cells are either
+callback is invalid or otherwise unnecessary. Empty cells are either
optional or must be evaluated on a case-by-case basis.
clock hardware characteristics
Required properties:
- compatible : Should be "ti,omap3-l3-smx" for OMAP3 family
Should be "ti,omap4-l3-noc" for OMAP4 family
+- reg: Contains L3 register address range for each noc domain.
- ti,hwmods: "l3_main_1", ... One hwmod for each noc domain.
Examples:
OMAP Timer bindings
Required properties:
-- compatible: Must be "ti,omap2-timer" for OMAP2+ controllers.
+- compatible: Should be set to one of the below. Please note that
+ OMAP44xx devices have timer instances that are 100%
+ register compatible with OMAP3xxx devices as well as
+ newer timers that are not 100% register compatible.
+ So for OMAP44xx devices timer instances may use
+ different compatible strings.
+
+ ti,omap2420-timer (applicable to OMAP24xx devices)
+ ti,omap3430-timer (applicable to OMAP3xxx/44xx devices)
+ ti,omap4430-timer (applicable to OMAP44xx devices)
+ ti,omap5430-timer (applicable to OMAP543x devices)
+ ti,am335x-timer (applicable to AM335x devices)
+ ti,am335x-timer-1ms (applicable to AM335x devices)
+
- reg: Contains timer register address range (base address and
length).
- interrupts: Contains the interrupt information for the timer. The
Example:
timer12: timer@48304000 {
- compatible = "ti,omap2-timer";
+ compatible = "ti,omap3430-timer";
reg = <0x48304000 0x400>;
interrupts = <95>;
ti,hwmods = "timer12"
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.

+Binding for the axi-clkgen clock generator
+
+This binding uses the common clock binding[1].
+
+[1] Documentation/devicetree/bindings/clock/clock-bindings.txt
+
+Required properties:
+- compatible : shall be "adi,axi-clkgen".
+- #clock-cells : from common clock binding; Should always be set to 0.
+- reg : Address and length of the axi-clkgen register set.
+- clocks : Phandle and clock specifier for the parent clock.
+
+Optional properties:
+- clock-output-names : From common clock binding.
+
+Example:
+ clock@0xff000000 {

+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.

+NVIDIA Tegra20/Tegra30/Tegra114 I2C controller driver.
+
+Required properties:
+- compatible : should be:
+ "nvidia,tegra114-i2c"
+ "nvidia,tegra30-i2c"
+ "nvidia,tegra20-i2c"
+ "nvidia,tegra20-i2c-dvc"
+ Details of compatible are as follows:
+ nvidia,tegra20-i2c-dvc: Tegra20 has specific I2C controller called as DVC I2C
+ controller. This only support master mode of I2C communication. Register
+ interface/offset and interrupts handling are different than generic I2C
+ controller. Driver of DVC I2C controller is only compatible with
+ "nvidia,tegra20-i2c-dvc".
+ nvidia,tegra20-i2c: Tegra20 has 4 generic I2C controller. This can support
+ master and slave mode of I2C communication. The i2c-tegra driver only
+ support master mode of I2C communication. Driver of I2C controller is
+ only compatible with "nvidia,tegra20-i2c".
+ nvidia,tegra30-i2c: Tegra30 has 5 generic I2C controller. This controller is
+ very much similar to Tegra20 I2C controller with additional feature:
+ Continue Transfer Support. This feature helps to implement M_NO_START
+ as per I2C core API transfer flags. Driver of I2C controller is
+ compatible with "nvidia,tegra30-i2c" to enable the continue transfer
+ support. This is also compatible with "nvidia,tegra20-i2c" without
+ continue transfer support.
+ nvidia,tegra114-i2c: Tegra114 has 5 generic I2C controller. This controller is
+ very much similar to Tegra30 I2C controller with some hardware
+ modification:
+ - Tegra30/Tegra20 I2C controller has 2 clock source called div-clk and
+ fast-clk. Tegra114 has only one clock source called as div-clk and
+ hence clock mechanism is changed in I2C controller.
+ - Tegra30/Tegra20 I2C controller has enabled per packet transfer by
+ default and there is no way to disable it. Tegra114 has this
+ interrupt disable by default and SW need to enable explicitly.
+ Due to above changes, Tegra114 I2C driver makes incompatible with
+ previous hardware driver. Hence, tegra114 I2C controller is compatible
+ with "nvidia,tegra114-i2c".
