Subject: [PATCH v3 00/10] Add Actions Semi S900 pinctrl and gpio support

This patchset adds pinctrl and gpio support for Actions Semi S900 SoC.
Pinctrl and gpio subsystems share the common set of register range but
implemented as individual drivers for making it less complex.

Pinmux functions are only accessible for pin groups while pinconf
parameters are available for both pin groups and individual pins.

gpio-line-names has been added for the Bubblegum-96 board matching the
96Boards CE specification v1.0.

Both pinctrl and gpio drivers are verified using the Bubblegum-96 board.

This patchset depends on the clock driver which is still under review:
https://lkml.org/lkml/2018/2/9/831

There is also S500 pinctrl and gpio driver developed by Andreas Farber
independently to this patchset.
https://github.com/afaerber/linux/commits/bg96-next

If this patchseries seems to be good enough to add base OWL pinctrl and
gpio support. Then, we may decide on adding S500 support on top of this later
by reusing the pinctrl definitions from Andreas.

Thanks,
Mani

Changes in v3:

* Simplified owl_gpio_set_reg() with _relaxed functions
* Added interrupt controller properties to gpio node bindings as suggested
by Rob
* Minor code cleanups

Changes in v2:

* Implemented each GPIO bank as its own gpio-controller
* Added gpio-ranges property
* Modified pin group to follow pad names instead of register names
* Incorporated review comments from Andy
* Incorporated review comments from Andreas
* Fixed the MODULE_LICENSE with respect to SPDX tag
* Added Reviewed by tag from Rob for pinctrl binding

+Actions Semi S900 Pin Controller
+
+This binding describes the pin controller found in the S900 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s900-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the 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".
+
+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 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.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:

Subject: [PATCH v3 08/10] gpio: Add gpio driver for Actions OWL S900 SoC

Add gpio driver for Actions Semi OWL family S900 SoC. Set of registers
controlling the gpio shares the same register range with pinctrl block.

GPIO registers are organized as 6 banks and each bank controls the
maximum of 32 gpios.

+* Actions Semi OWL GPIO controller bindings
+
+The GPIOs are organized as individual banks/ports with variable number
+of GPIOs. Each bank is represented as an individual GPIO controller.
+
+Required properties:
+- compatible : Should be "actions,s900-gpio"
+- reg : Address and range of the GPIO controller registers.
+- gpio-controller : Marks the device node as a GPIO controller.
+- #gpio-cells : Should be <2>. The first cell is the gpio number
+ and the second cell is used to specify optional
+ parameters.
+- interrupt-controller : Marks the device node as an interrupt controller.
+- #interrupt-cells : Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+
+Optional properties:
+- gpio-ranges : Mapping between GPIO and pinctrl
+
+Note: Each GPIO port should have an alias correctly numbered in "aliases"
+node.
+
+Examples:
+
+aliases {
+ gpio0 = &gpioa;
+ gpio1 = &gpiob;

Subject: [PATCH v3 04/10] pinctrl: actions: Add Actions S900 pinctrl driver

Add pinctrl driver for Actions Semi S900 SoC. The driver supports
pinctrl, pinmux and pinconf functionalities through a range of registers
common to both gpio driver and pinctrl driver.

Pinmux functionality is available only for the pin groups while the
pinconf functionality is available for both pin groups and individual
pins.

The previous (v2) version had Rob's Review tag, did you just forget
to add it or has something changed?

If nothing is changed I can add his tag when applying.

My bad. Slipped through the cracks.

I will send out a new version of the whole series, incorporating Andy's
pinctrl driver review.

Also, FYI this pacthseries depends on Clock driver patchset I have submitted
earlier. So far no reply from Stephen yet. He said that he is working on setting
up his new environment and will begin reviewing shortly.

Is the dependancy at runtime (driver is not functional without clocks) or compile
time (driver cannot build without other patchset landing)?

There is no build time dependency only runtime dependency. Driver is pretty
much useless without clock driver.

Also, there will be merge conflicts when this series gets applied independently.
Since there is no build time dependency, if Linus decides to apply it now, I
can generate a new independent patchset.

Okay. Will add a helper.

As stated in the binding doc, valid values for the slew rate parameter are:

0 - Slow
1 - Fast

Ack. Will return 0 directly.
