* Samsung Exynos5 G-Scaler device
G-Scaler is used for scaling and color space conversion on EXYNOS5 SoCs.
Required properties:
- compatible: should be "samsung,exynos5-gsc"
- reg: should contain G-Scaler physical address location and length.
- interrupts: should contain G-Scaler interrupt number
Example:
gsc_0: gsc@0x13e00000 {
compatible = "samsung,exynos5-gsc";
reg = <0x13e00000 0x1000>;
interrupts = <0 85 0>;
};
Aliases:
Each G-Scaler node should have a numbered alias in the aliases node,
in the form of gscN, N = 0...3. G-Scaler driver uses these aliases
to retrieve the device IDs using "of_alias_get_id()" call.
Example:
aliases {
gsc0 =&gsc_0;
gsc1 =&gsc_1;
gsc2 =&gsc_2;
gsc3 =&gsc_3;
};

Samsung GPIO and Pin Mux/Config controller
Samsung's ARM based SoC's integrates a GPIO and Pin mux/config hardware
controller. It controls the input/output settings on the available pads/pins
and also provides ability to multiplex and configure the output of various
on-chip controllers onto these pads.
Required Properties:
- compatible: should be one of the following.
- "samsung,pinctrl-exynos4210": for Exynos4210 compatible pin-controller.
- "samsung,pinctrl-exynos5250": for Exynos5250 compatible pin-controller.
- reg: Base address of the pin controller hardware module and length of
the address space it occupies.
- interrupts: interrupt specifier for the controller. The format and value of
the interrupt specifier depends on the interrupt parent for the controller.
- Pin mux/config groups as child nodes: The pin mux (selecting pin function
mode) and pin config (pull up/down, driver strength) settings are represented
as child nodes of the pin-controller node. There should be atleast one
child node and there is no limit on the count of these child nodes.
The child node should contain a list of pin(s) on which a particular pin
function selection or pin configuration (or both) have to applied. This
list of pins is specified using the property name "samsung,pins". There
should be atleast one pin specfied for this property and there is no upper
limit on the count of pins that can be specified. The pins are specified
using pin names which are derived from the hardware manual of the SoC. As
an example, the pins in GPA0 bank of the pin controller can be represented
as "gpa0-0", "gpa0-1", "gpa0-2" and so on. The names should be in lower case.
The format of the pin names should be (as per the hardware manual)
"[pin bank name]-[pin number within the bank]".
The pin function selection that should be applied on the pins listed in the
child node is specified using the "samsung,pin-function" property. The value
of this property that should be applied to each of the pins listed in the
"samsung,pins" property should be picked from the hardware manual of the SoC
for the specified pin group. This property is optional in the child node if
no specific function selection is desired for the pins listed in the child
node. The value of this property is used as-is to program the pin-controller
function selector register of the pin-bank.
The child node can also optionally specify one or more of the pin
configuration that should be applied on all the pins listed in the
"samsung,pins" property of the child node. The following pin configuration
properties are supported.
- samsung,pin-pud: Pull up/down configuration.
- samsung,pin-drv: Drive strength configuration.
- samsung,pin-pud-pdn: Pull up/down configuration in power down mode.
- samsung,pin-drv-pdn: Drive strength configuration in power down mode.
The values specified by these config properties should be derived from the
hardware manual and these values are programmed as-is into the pin
pull up/down and driver strength register of the pin-controller.
Note: A child should include atleast a pin function selection property or
pin configuration property (one or more) or both.
The client nodes that require a particular pin function selection and/or
pin configuration should use the bindings listed in the "pinctrl-bindings.txt"
file.
External GPIO and Wakeup Interrupts:
The controller supports two types of external interrupts over gpio. The first
is the external gpio interrupt and second is the external wakeup interrupts.
The difference between the two is that the external wakeup interrupts can be
used as system wakeup events.
A. External GPIO Interrupts: For supporting external gpio interrupts, the
following properties should be specified in the pin-controller device node.
- interrupt-controller: identifies the controller node as interrupt-parent.
- #interrupt-cells: the value of this property should be 2.
- First Cell: represents the external gpio interrupt number local to the
external gpio interrupt space of the controller.
- Second Cell: flags to identify the type of the interrupt
- 1 = rising edge triggered
- 2 = falling edge triggered
- 3 = rising and falling edge triggered
- 4 = high level triggered
- 8 = low level triggered
B. External Wakeup Interrupts: For supporting external wakeup interrupts, a
child node representing the external wakeup interrupt controller should be
included in the pin-controller device node. This child node should include
the following properties.
- compatible: identifies the type of the external wakeup interrupt controller
The possible values are:
- samsung,exynos4210-wakeup-eint: represents wakeup interrupt controller
found on Samsung Exynos4210 SoC.
- interrupt-parent: phandle of the interrupt parent to which the external
wakeup interrupts are forwarded to.
- interrupt-controller: identifies the node as interrupt-parent.
- #interrupt-cells: the value of this property should be 2
- First Cell: represents the external wakeup interrupt number local to
the external wakeup interrupt space of the controller.
- Second Cell: flags to identify the type of the interrupt
- 1 = rising edge triggered
- 2 = falling edge triggered
- 3 = rising and falling edge triggered
- 4 = high level triggered
- 8 = low level triggered
Aliases:
All the pin controller nodes should be represented in the aliases node using
the following format 'pinctrl{n}' where n is a unique number for the alias.
Example 1: A pin-controller node with pin groups.
pinctrl_0: pinctrl@11400000 {
compatible = "samsung,pinctrl-exynos4210";
reg = <0x11400000 0x1000>;
interrupts = <0 47 0>;
uart0_data: uart0-data {
samsung,pins = "gpa0-0", "gpa0-1";
samsung,pin-function = <2>;
samsung,pin-pud = <0>;
samsung,pin-drv = <0>;
};
uart0_fctl: uart0-fctl {
samsung,pins = "gpa0-2", "gpa0-3";
samsung,pin-function = <2>;
samsung,pin-pud = <0>;
samsung,pin-drv = <0>;
};
uart1_data: uart1-data {
samsung,pins = "gpa0-4", "gpa0-5";
samsung,pin-function = <2>;
samsung,pin-pud = <0>;
samsung,pin-drv = <0>;
};
uart1_fctl: uart1-fctl {
samsung,pins = "gpa0-6", "gpa0-7";
samsung,pin-function = <2>;
samsung,pin-pud = <0>;
samsung,pin-drv = <0>;
};
i2c2_bus: i2c2-bus {
samsung,pins = "gpa0-6", "gpa0-7";
samsung,pin-function = <3>;
samsung,pin-pud = <3>;
samsung,pin-drv = <0>;
};
};
Example 2: A pin-controller node with external wakeup interrupt controller node.
pinctrl_1: pinctrl@11000000 {
compatible = "samsung,pinctrl-exynos4210";
reg = <0x11000000 0x1000>;
interrupts = <0 46 0>;
interrupt-controller;
#interrupt-cells = <2>;
wakup_eint: wakeup-interrupt-controller {
compatible = "samsung,exynos4210-wakeup-eint";
interrupt-parent = <&gic>;
interrupt-controller;
#interrupt-cells = <2>;
interrupts = <0 16 0>, <0 17 0>, <0 18 0>, <0 19 0>,
<0 20 0>, <0 21 0>, <0 22 0>, <0 23 0>,
<0 24 0>, <0 25 0>, <0 26 0>, <0 27 0>,
<0 28 0>, <0 29 0>, <0 30 0>, <0 31 0>,
<0 32 0>;
};
};
Example 3: A uart client node that supports 'default' and 'flow-control' states.
uart@13800000 {
compatible = "samsung,exynos4210-uart";
reg = <0x13800000 0x100>;
interrupts = <0 52 0>;
pinctrl-names = "default", "flow-control;
pinctrl-0 = <&uart0_data>;
pinctrl-1 = <&uart0_data &uart0_fctl>;
};
Example 4: Set up the default pin state for uart controller.
static int s3c24xx_serial_probe(struct platform_device *pdev) {
struct pinctrl *pinctrl;
...
...
pinctrl = devm_pinctrl_get_select_default(&pdev->dev);

If you say Y here, the LEDs on your machine will be used
to provide useful information about your current system status.
If you are compiling a kernel for a NetWinder or EBSA-285, you will
be able to select which LEDs are active using the options below. If
you are compiling a kernel for the EBSA-110 or the LART however, the
red LED will simply flash regularly to indicate that the system is
still functional. It is safe to say Y here if you have a CATS
system, but the driver will do nothing.

If you say Y here, one of the system LEDs (the green one on the
NetWinder, the amber one on the EBSA285, or the red one on the LART)
will flash regularly to indicate that the system is still
operational. This is mainly useful to kernel hackers who are
debugging unstable kernels.
The LART uses the same LED for both Timer LED and CPU usage LED
functions. You may choose to use both, but the Timer LED function
will overrule the CPU usage LED.

If you say Y here, the red LED will be used to give a good real
time indication of CPU usage, by lighting whenever the idle task
is not currently executing.
The LART uses the same LED for both Timer LED and CPU usage LED
functions. You may choose to use both, but the Timer LED function
will overrule the CPU usage LED.
