Code Releases Activity

This is the big bulk of pin control changes for the v4.13 series: 

Core:
 
 - The documentation is moved over to RST.
 - We now have agreed bindings for enabling input and output
   buffers without actually enabling input and/or output on a
   pin. We are chiseling out some details of pin control
   electronics.
 
 New drivers:
 
 - ZTE ZX
 - Renesas RZA1
 - MIPS Ingenic JZ47xx: also switch over existing drivers in the
   tree to use this pin controller and consolidate earlier
   spread out code.
 - Microschip MCP23S08: this driver is migrated from the GPIO
   subsystem and totally rewritten to use proper pin control.
   All users are switched over.
 
 New subdrivers:
 
 - Renesas R8A7743 and R8A7745.
 - Allwinner Sunxi A83T R_PIO.
 - Marvell MVEBU Armada CP110 and AP806.
 - Intel Cannon Lake PCH.
 - Qualcomm IPQ8074.
 
 Notable improvements:
 
 - IRQ support on the Marvell MVEBU Armada 37xx.
 - Meson driver supports HDMI CEC, AO, I2S, SPDIF and PWM.
 - Rockchip driver now supports iomux-route switching for
   RK3228, RK3328 and RK3399.
 - Rockchip A10 and A20 are merged into a single driver.
 - STM32 has improved GPIO support.
 - Samsung Exynos drivers are split per ARMv7 and ARMv8.
 - Marvell MVEBU is converted to use regmap for register
   access.
 
 Maintenance:
 
 - Several Renesas SH-PFC refactorings and updates.

Ingenic jz47xx pin controller
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".
For the jz47xx SoCs, pin control is tightly bound with GPIO ports. All pins may
be used as GPIOs, multiplexed device functions are configured within the
GPIO port configuration registers and it is typical to refer to pins using the
naming scheme "PxN" where x is a character identifying the GPIO port with
which the pin is associated and N is an integer from 0 to 31 identifying the
pin within that GPIO port. For example PA0 is the first pin in GPIO port A, and
PB31 is the last pin in GPIO port B. The jz4740 contains 4 GPIO ports, PA to
PD, for a total of 128 pins. The jz4780 contains 6 GPIO ports, PA to PF, for a
total of 192 pins.
Required properties:
--------------------
- compatible: One of:
- "ingenic,jz4740-pinctrl"
- "ingenic,jz4770-pinctrl"
- "ingenic,jz4780-pinctrl"
- reg: Address range of the pinctrl registers.
GPIO sub-nodes
--------------
The pinctrl node can have optional sub-nodes for the Ingenic GPIO driver;
please refer to ../gpio/ingenic,gpio.txt.
Example:
--------
pinctrl: pin-controller@10010000 {
compatible = "ingenic,jz4740-pinctrl";
reg = <0x10010000 0x400>;

* ZTE ZX Pin Controller
The pin controller on ZTE ZX platforms is kinda of hybrid. It consists of
a main controller and an auxiliary one. For example, on ZX296718 SoC, the
main controller is TOP_PMM and the auxiliary one is AON_IOCFG. Both
controllers work together to control pin multiplexing and configuration in
the way illustrated as below.
GMII_RXD3 ---+

DVI1_HS ---+----------------------------- GMII_RXD3 (TOP pin)
|
BGPIO16 ---+ ^

| AGPIO10 ---+------ KEY_ROW2 (AON pin)
I2S0_DOUT3 ---+ |
|-----------------------+
PWM_OUT3 ---+
|
VGA_VS1 ---+
For most of pins like GMII_RXD3 in the figure, the pinmux function is
controlled by TOP_PMM block only, and this type of pins are meant by term
'TOP pins'. For pins like KEY_ROW2, the pinmux is controlled by both
TOP_PMM and AON_IOCFG blocks, as the available multiplexing functions for
the pin spread in both controllers. This type of pins are called 'AON pins'.
Though pinmux implementation is quite different, pinconf is same for both
types of pins. Both are controlled by auxiliary controller, i.e. AON_IOCFG
on ZX296718.
Required properties:
- compatible: should be "zte,zx296718-pmm".
- reg: the register physical address and length.
- zte,auxiliary-controller: phandle to the auxiliary pin controller which
implements pinmux for AON pins and pinconf for all pins.
The following pin configuration are supported. Please refer to
pinctrl-bindings.txt in this directory for more details of the common
pinctrl bindings used by client devices.
- bias-pull-up
- bias-pull-down
- drive-strength
- input-enable
- slew-rate

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".
The pin configuration nodes act as a container for an arbitrary number of
subnodes. Each of these subnodes represents some desired configuration for a
pin, a group, or a list of pins or groups. This configuration can include the
mux function to select on those pin(s)/group(s), and various pin configuration
parameters, such as pull-up, drive strength, etc.
PIN CONFIGURATION NODES:
The name of each subnode is not important; all subnodes should be enumerated
and processed purely based on their content.
Each subnode only affects those parameters that are explicitly listed. In
other words, a subnode that lists a mux function but no pin configuration
parameters implies no information about any pin configuration parameters.
Similarly, a pin subnode that describes a pullup parameter implies no
information about e.g. the mux function.
The following generic properties as defined in pinctrl-bindings.txt are valid
to specify in a pin configuration subnode:

this subnode. Valid pins are:

Renesas RZ/A1 combined Pin and GPIO controller
The Renesas SoCs of the RZ/A1 family feature a combined Pin and GPIO controller,
named "Ports" in the hardware reference manual.
Pin multiplexing and GPIO configuration is performed on a per-pin basis
writing configuration values to per-port register sets.
Each "port" features up to 16 pins, each of them configurable for GPIO
function (port mode) or in alternate function mode.
Up to 8 different alternate function modes exist for each single pin.
Pin controller node
-------------------
Required properties:
- compatible
this shall be "renesas,r7s72100-ports".
- reg
address base and length of the memory area where the pin controller
hardware is mapped to.
Example:
Pin controller node for RZ/A1H SoC (r7s72100)
pinctrl: pin-controller@fcfe3000 {
compatible = "renesas,r7s72100-ports";
reg = <0xfcfe3000 0x4230>;
};
Sub-nodes
---------
The child nodes of the pin controller node describe a pin multiplexing
function or a GPIO controller alternatively.
- Pin multiplexing sub-nodes:
A pin multiplexing sub-node describes how to configure a set of
(or a single) pin in some desired alternate function mode.
A single sub-node may define several pin configurations.
A few alternate function require special pin configuration flags to be
supplied along with the alternate function configuration number.
The hardware reference manual specifies when a pin function requires
"software IO driven" mode to be specified. To do so use the generic
properties from the <include/linux/pinctrl/pinconf_generic.h> header file
to instruct the pin controller to perform the desired pin configuration
operation.
Please refer to pinctrl-bindings.txt to get to know more on generic
pin properties usage.
The allowed generic formats for a pin multiplexing sub-node are the
following ones:
node-1 {
pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
GENERIC_PINCONFIG;
};
node-2 {
sub-node-1 {
pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
GENERIC_PINCONFIG;
};
sub-node-2 {
pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
GENERIC_PINCONFIG;
};
...
sub-node-n {
pinmux = <PIN_ID_AND_MUX>, <PIN_ID_AND_MUX>, ... ;
GENERIC_PINCONFIG;
};
};
Use the second format when pins part of the same logical group need to have
different generic pin configuration flags applied.
Client sub-nodes shall refer to pin multiplexing sub-nodes using the phandle
of the most external one.
Eg.
client-1 {
...
pinctrl-0 = <&node-1>;
...
};
client-2 {
...
pinctrl-0 = <&node-2>;
...
};
Required properties:
- pinmux:
integer array representing pin number and pin multiplexing configuration.
When a pin has to be configured in alternate function mode, use this
property to identify the pin by its global index, and provide its
alternate function configuration number along with it.
When multiple pins are required to be configured as part of the same
alternate function they shall be specified as members of the same
argument list of a single "pinmux" property.
Helper macros to ease assembling the pin index from its position
(port where it sits on and pin number) and alternate function identifier
are provided by the pin controller header file at:
<include/dt-bindings/pinctrl/r7s72100-pinctrl.h>
Integers values in "pinmux" argument list are assembled as:
((PORT * 16 + PIN) | MUX_FUNC << 16)
Optional generic properties:
- input-enable:
enable input bufer for pins requiring software driven IO input
operations.
- output-high:
enable output buffer for pins requiring software driven IO output
operations. output-low can be used alternatively, as line value is
ignored by the driver.
The hardware reference manual specifies when a pin has to be configured to
work in bi-directional mode and when the IO direction has to be specified
by software. Bi-directional pins are managed by the pin controller driver
internally, while software driven IO direction has to be explicitly
selected when multiple options are available.
Example:
A serial communication interface with a TX output pin and an RX input pin.
&pinctrl {
scif2_pins: serial2 {
pinmux = <RZA1_PINMUX(3, 0, 6)>, <RZA1_PINMUX(3, 2, 4)>;
};
};
Pin #0 on port #3 is configured as alternate function #6.
Pin #2 on port #3 is configured as alternate function #4.
Example 2:
I2c master: both SDA and SCL pins need bi-directional operations
&pinctrl {
i2c2_pins: i2c2 {
pinmux = <RZA1_PINMUX(1, 4, 1)>, <RZA1_PINMUX(1, 5, 1)>;
};
};
Pin #4 on port #1 is configured as alternate function #1.
Pin #5 on port #1 is configured as alternate function #1.
Both need to work in bi-directional mode, the driver manages this internally.
Example 3:
Multi-function timer input and output compare pins.
Configure TIOC0A as software driven input and TIOC0B as software driven
output.
&pinctrl {
tioc0_pins: tioc0 {
tioc0_input_pins {
pinumx = <RZA1_PINMUX(4, 0, 2)>;
input-enable;
};
tioc0_output_pins {
pinmux = <RZA1_PINMUX(4, 1, 1)>;
output-enable;
};
};
};
&tioc0 {
...
pinctrl-0 = <&tioc0_pins>;
...
};
Pin #0 on port #4 is configured as alternate function #2 with IO direction
specified by software as input.
Pin #1 on port #4 is configured as alternate function #1 with IO direction
specified by software as output.
- GPIO controller sub-nodes:
Each port of the r7s72100 pin controller hardware is itself a GPIO controller.
Different SoCs have different numbers of available pins per port, but
generally speaking, each of them can be configured in GPIO ("port") mode
on this hardware.
Describe GPIO controllers using sub-nodes with the following properties.
Required properties:
- gpio-controller
empty property as defined by the GPIO bindings documentation.
- #gpio-cells
number of cells required to identify and configure a GPIO.
Shall be 2.
- gpio-ranges
Describes a GPIO controller specifying its specific pin base, the pin
base in the global pin numbering space, and the number of controlled
pins, as defined by the GPIO bindings documentation. Refer to
Documentation/devicetree/bindings/gpio/gpio.txt file for a more detailed
description.
Example:
A GPIO controller node, controlling 16 pins indexed from 0.
The GPIO controller base in the global pin indexing space is pin 48, thus
pins [0 - 15] on this controller map to pins [48 - 63] in the global pin
indexing space.
port3: gpio-3 {
gpio-controller;
#gpio-cells = <2>;
gpio-ranges = <&pinctrl 0 48 16>;
};
A device node willing to use pins controlled by this GPIO controller, shall
refer to it as follows:
led1 {
gpios = <&port3 10 GPIO_ACTIVE_LOW>;
};
