== Pad Control ==
On Tegra SoCs a pad is a set of pins which are configured as a group.
The pin grouping is a fixed attribute of the hardware. The PMC can be
used to set pad power state and signaling voltage. A pad can be either
in active or power down mode. The support for power state and signaling
voltage configuration varies depending on the pad in question. 3.3 V and
1.8 V signaling voltages are supported on pins where software
controllable signaling voltage switching is available.
Pad configurations are described with pin configuration nodes which
are placed under the pmc node and they are referred to by the pinctrl
client properties. For more information see
Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt.
The following pads are present on Tegra186:
csia csib dsi mipi-bias
pex-clk-bias pex-clk3 pex-clk2 pex-clk1
usb0 usb1 usb2 usb-bias
uart audio hsic dbg

sdmmc4 cam dsib dsic
dsid csic csid csie
dsif spi ufs dmic-hv
edp sdmmc1-hv sdmmc3-hv conn
audio-hv ao-hv
Required pin configuration properties:
- pins: A list of strings, each of which contains the name of a pad
to be configured.
Optional pin configuration properties:
- low-power-enable: Configure the pad into power down mode
- low-power-disable: Configure the pad into active mode
- power-source: Must contain either TEGRA_IO_PAD_VOLTAGE_1V8 or
TEGRA_IO_PAD_VOLTAGE_3V3 to select between signaling voltages.
The values are defined in
include/dt-bindings/pinctrl/pinctrl-tegra-io-pad.h.
Note: The power state can be configured on all of the above pads except
for ao-hv. Following pads have software configurable signaling
voltages: sdmmc2-hv, dmic-hv, sdmmc1-hv, sdmmc3-hv, audio-hv,
ao-hv.

Note: The power state can be configured on all of the Tegra124 and
Tegra132 pads. None of the Tegra124 or Tegra132 pads support
signaling voltage switching.
Note: All of the listed Tegra210 pads except pex-cntrl support power

* Hisilicon Hi3670 Clock Controller
The Hi3670 clock controller generates and supplies clock to various
controllers within the Hi3670 SoC.
Required Properties:
- compatible: the compatible should be one of the following strings to
indicate the clock controller functionality.
- "hisilicon,hi3670-crgctrl"
- "hisilicon,hi3670-pctrl"
- "hisilicon,hi3670-pmuctrl"
- "hisilicon,hi3670-sctrl"

- "hisilicon,hi3670-media2-crg"
- reg: physical base address of the controller and length of memory mapped
region.
- #clock-cells: should be 1.
Each clock is assigned an identifier and client nodes use this identifier
to specify the clock which they consume.
All these identifier could be found in <dt-bindings/clock/hi3670-clock.h>.
Examples:
crg_ctrl: clock-controller@fff35000 {

......@@ -6,6 +6,14 @@ Required properties:
- interrupts: Should contain CCM interrupt
- #clock-cells: Should be <1>
Optional properties:
- fsl,pmic-stby-poweroff: Configure CCM to assert PMIC_STBY_REQ signal
on power off.
Use this property if the SoC should be powered off by external power
management IC (PMIC) triggered via PMIC_STBY_REQ signal.
Boards that are designed to initiate poweroff on PMIC_ON_REQ signal should
be using "syscon-poweroff" driver instead.
The clock consumer should specify the desired clock by having the clock
ID in its "clocks" phandle cell. See include/dt-bindings/clock/imx6qdl-clock.h
for the full list of i.MX6 Quad and DualLite clock IDs.
