Hi all,

Here's v3 of the Aspeed pinctrl and gpio driver patches, which aims to address
the review comments on v2:

  https://lkml.org/lkml/2016/8/19/394

The combined series has been tested with both the AST2400 (g4) and AST2500 (g5)
SoCs on OpenPOWER Palmetto and Aspeed AST2500 EVB machines respectively, and
similarly in QEMU with the palmetto-bmc and ast2500-evb machines[1].

Since v2:

* Add interrupt-controller as a required property to gpio devicetree node
* Drop unit address in pinctrl devicetree example
* PINCTRL_ASPEED depends on MFD_SYSCON rather than selecting it
* Use regmap_update_bits() where possible

Since v1:

* Split the series in two: driver and SoC patches.
* Update devicetree bindings documentation
* Add documentation for aspeed pinctrl core functions
* Fix bugs in existing signal descriptors
* Add a number of pin and mux function declarations
* Provide debug information on unexpected conditions

Cheers,

Andrew

+Aspeed Pin Controllers
+----------------------
+
+The Aspeed SoCs vary in functionality inside a generation but have a common mux
+device register layout.
+
+Required properties:
+- compatible : Should be any one of the following:
+		"aspeed,ast2400-pinctrl"
+		"aspeed,g4-pinctrl"
+		"aspeed,ast2500-pinctrl"
+		"aspeed,g5-pinctrl"
+
+The pin controller node should be a child of a syscon node with the required
+property:
+- compatible: "syscon", "simple-mfd"
+
+Refer to the the bindings described in
+Documentation/devicetree/bindings/mfd/syscon.txt
+
+Subnode Format
+--------------
+
+The required properties of child nodes are (as defined in pinctrl-bindings):
+- function
+- groups
+
+Each function has only one associated pin group. Each group is named by its
+function. The following values for the function and groups properties are
+supported:
+
+aspeed,ast2400-pinctrl, aspeed,g4-pinctrl:
+
+ACPI BMCINT DDCCLK DDCDAT FLACK FLBUSY FLWP GPID0 GPIE0 GPIE2 GPIE4 GPIE6 I2C10

The Aspeed SoCs typically provide more than 200 pins for GPIO and other
functions. The signal enabled on a pin is determined on a priority
basis, where a given pin can provide a number of different signal types.

In addition to the priority levels, the Aspeed pin controllers describe
the signal active on a pin by compound logical expressions involving
multiple operators, registers and bits. Some difficulty arises as a
pin's function bit masks for each priority level are frequently not the
same (i.e. we cannot just flip a bit to change from a high to low
priority signal), or even in the same register(s). Some configuration
bits affect multiple pins, while in other cases the signals for a bus
must each be enabled individually.

Together, these features give rise to some complexity in the
implementation. A more complete description of the complexities is
provided in the associated header file.

The patch doesn't implement pinctrl/pinmux/pinconf for any particular
Aspeed SoC, rather it adds the framework for defining pinmux
configurations.

+ * The ASPEED SoCs provide typically more than 200 pins for GPIO and other
+ * functions. The SoC function enabled on a pin is determined on a priority
+ * basis where a given pin can provide a number of different signal types.
+ *
+ * The signal active on a pin is described by both a priority level and
+ * compound logical expressions involving multiple operators, registers and
+ * bits. Some difficulty arises as the pin's function bit masks for each
+ * priority level are frequently not the same (i.e. cannot just flip a bit to
+ * change from a high to low priority signal), or even in the same register.
+ * Further, not all signals can be unmuxed, as some expressions depend on
+ * values in the hardware strapping register (which is treated as read-only).
+ *
+ * SoC Multi-function Pin Expression Examples
+ * ------------------------------------------
+ *
+ * Here are some sample mux configurations from the AST2400 and AST2500
+ * datasheets to illustrate the corner cases, roughly in order of least to most
+ * corner. The signal priorities are in decending order from P0 (highest).
+ *
+ * D6 is a pin with a single function (beside GPIO); a high priority signal
+ * that participates in one function:
+ *
+ * Ball | Default | P0 Signal | P0 Expression               | P1 Signal | P1 Expression | Other
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *  D6    GPIOA0    MAC1LINK    SCU80[0]=1                                                GPIOA0
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * C5 is a multi-signal pin (high and low priority signals). Here we touch
+ * different registers for the different functions that enable each signal:
+ *
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *  C5    GPIOA4    SCL9        SCU90[22]=1                   TIMER5      SCU80[4]=1      GPIOA4
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * E19 is a single-signal pin with two functions that influence the active
+ * signal. In this case both bits have the same meaning - enable a dedicated
+ * LPC reset pin. However it's not always the case that the bits in the
+ * OR-relationship have the same meaning.
+ *
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *  E19   GPIOB4    LPCRST#     SCU80[12]=1 | Strap[14]=1                                 GPIOB4
+ * -----+---------+-----------+-----------------------------+-----------+---------------+----------
+ *
+ * For example, pin B19 has a low-priority signal that's enabled by two
+ * distinct SoC functions: A specific SIOPBI bit in register SCUA4, and an ACPI
+ * bit in the STRAP register. The ACPI bit configures signals on pins in
+ * addition to B19. Both of the low priority functions as well as the high
+ * priority function must be disabled for GPIOF1 to be used.
+ *
+ * Ball | Default | P0 Signal | P0 Expression                           | P1 Signal | P1 Expression                          | Other
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *  B19   GPIOF1    NDCD4       SCU80[25]=1                               SIOPBI#     SCUA4[12]=1 | Strap[19]=0                GPIOF1
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *
+ * For pin E18, the SoC ANDs the expected state of three bits to determine the
+ * pin's active signal:
+ *
+ * * SCU3C[3]: Enable external SOC reset function
+ * * SCU80[15]: Enable SPICS1# or EXTRST# function pin
+ * * SCU90[31]: Select SPI interface CS# output
+ *
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *  E18   GPIOB7    EXTRST#     SCU3C[3]=1 & SCU80[15]=1 & SCU90[31]=0    SPICS1#     SCU3C[3]=1 & SCU80[15]=1 & SCU90[31]=1   GPIOB7
+ * -----+---------+-----------+-----------------------------------------+-----------+----------------------------------------+----------
+ *
+ * (Bits SCU3C[3] and SCU80[15] appear to only be used in the expressions for
+ * selecting the signals on pin E18)
+ *
+ * Pin T5 is a multi-signal pin with a more complex configuration:
+ *
+ * Ball | Default | P0 Signal | P0 Expression                | P1 Signal | P1 Expression | Other
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *  T5    GPIOL1    VPIDE       SCU90[5:4]!=0 & SCU84[17]=1    NDCD1       SCU84[17]=1     GPIOL1
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * The high priority signal configuration is best thought of in terms of its
+ * exploded form, with reference to the SCU90[5:4] bits:
+ *
+ * * SCU90[5:4]=00: disable
+ * * SCU90[5:4]=01: 18 bits (R6/G6/B6) video mode.
+ * * SCU90[5:4]=10: 24 bits (R8/G8/B8) video mode.
+ * * SCU90[5:4]=11: 30 bits (R10/G10/B10) video mode.
+ *
+ * Re-writing:
+ *
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *  T5    GPIOL1    VPIDE      (SCU90[5:4]=1 & SCU84[17]=1)    NDCD1       SCU84[17]=1     GPIOL1
+ *                             | (SCU90[5:4]=2 & SCU84[17]=1)
+ *                             | (SCU90[5:4]=3 & SCU84[17]=1)
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * For reference the SCU84[17] bit configure the "UART1 NDCD1 or Video VPIDE
+ * function pin", where the signal itself is determined by whether SCU94[5:4]
+ * is disabled or in one of the 18, 24 or 30bit video modes.
+ *
+ * Other video-input-related pins require an explicit state in SCU90[5:4], e.g.
+ * W1 and U5:
+ *
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *  W1    GPIOL6    VPIB0       SCU90[5:4]=3 & SCU84[22]=1     TXD1        SCU84[22]=1     GPIOL6
+ *  U5    GPIOL7    VPIB1       SCU90[5:4]=3 & SCU84[23]=1     RXD1        SCU84[23]=1     GPIOL7
+ * -----+---------+-----------+------------------------------+-----------+---------------+----------
+ *
+ * The examples of T5 and W1 are particularly fertile, as they also demonstrate
+ * that despite operating as part of the video input bus each signal needs to
+ * be enabled individually via it's own SCU84 (in the cases of T5 and W1)
+ * register bit. This is a little crazy if the bus doesn't have optional
+ * signals, but is used to decent effect with some of the UARTs where not all
+ * signals are required. However, this isn't done consistently - UART1 is
+ * enabled on a per-pin basis, and by contrast, all signals for UART6 are
+ * enabled by a single bit.
+ *
+ * Further, the high and low priority signals listed in the table above share
+ * a configuration bit. The VPI signals should operate in concert in a single
+ * function, but the UART signals should retain the ability to be configured
+ * independently. This pushes the implementation down the path of tagging a
+ * signal's expressions with the function they participate in, rather than
+ * defining masks affecting multiple signals per function. The latter approach
+ * fails in this instance where applying the configuration for the UART pin of
+ * interest will stomp on the state of other UART signals when disabling the
+ * VPI functions on the current pin.

+ * -----+------------+-----------+---------------------------+-----------+---------------+------------
+ *
+ * A12 demonstrates that the "Other" signal isn't always GPIO - in this case
+ * GPIOT0 is a high-priority signal and RGMII1TXCK is Other. Thus, GPIO
+ * should be treated like any other signal type with full function expression
+ * requirements, and not assumed to be the default case. Separately, GPIOT0 and
+ * GPIOT1's signal descriptor bits are distinct, therefore we must iterate all
+ * pins in the function's group to disable the higher-priority signals such
+ * that the signal for the function of interest is correctly enabled.
+ *
+ * Finally, three priority levels aren't always enough; the AST2500 brings with
+ * it 18 pins of five priority levels, however the 18 pins only use three of
+ * the five priority levels.
+ *
+ * Ultimately the requirement to control pins in the examples above drive the
+ * design:
+ *
+ * * Pins provide signals according to functions activated in the mux
+ *   configuration
+ *
+ * * Pins provide up to five signal types in a priority order
+ *
+ * * For priorities levels defined on a pin, each priority provides one signal
+ *
+ * * Enabling lower priority signals requires higher priority signals be
+ *   disabled
+ *
+ * * A function represents a set of signals; functions are distinct if their
+ *   sets of signals are not equal
+ *
+ * * Signals participate in one or more functions
+ *
+ * * A function is described by an expression of one or more signal
+ *   descriptors, which compare bit values in a register
+ *
+ * * A signal expression is the smallest set of signal descriptors whose
+ *   comparisons must evaluate 'true' for a signal to be enabled on a pin.
+ *
+ * * A function's signal is active on a pin if evaluating all signal
+ *   descriptors in the pin's signal expression for the function yields a 'true'
+ *   result
+ *
+ * * A signal at a given priority on a given pin is active if any of the
+ *   functions in which the signal participates are active, and no higher
+ *   priority signal on the pin is active
+ *
+ * * GPIO is configured per-pin
+ *
+ * And so:
+ *
+ * * To disable a signal, any function(s) activating the signal must be
+ *   disabled
+ *
+ * * Each pin must know the signal expressions of functions in which it
+ *   participates, for the purpose of enabling the Other function. This is done
+ *   by deactivating all functions that activate higher priority signals on the
+ *   pin.
+ *
+ * As a concrete example:
+ *
+ * * T5 provides three signals types: VPIDE, NDCD1 and GPIO
+ *
+ * * The VPIDE signal participates in 3 functions: VPI18, VPI24 and VPI30
+ *
+ * * The NDCD1 signal participates in just its own NDCD1 function
+ *
+ * * VPIDE is high priority, NDCD1 is low priority, and GPIOL1 is the least
+ *   prioritised
+ *
+ * * The prerequisit for activating the NDCD1 signal is that the VPI18, VPI24
+ *   and VPI30 functions all be disabled
+ *
+ * * Similarly, all of VPI18, VPI24, VPI30 and NDCD1 functions must be disabled
+ *   to provide GPIOL6
+ *
+ * Considerations
+ * --------------
+ *
+ * If pinctrl allows us to allocate a pin we can configure a function without
+ * concern for the function of already allocated pins, if pin groups are
+ * created with respect to the SoC functions in which they participate. This is
+ * intuitive, but it did not feel obvious from the bit/pin relationships.
+ *
+ * Conversely, failing to allocate all pins in a group indicates some bits (as
+ * well as pins) required for the group's configuration will already be in use,
+ * likely in a way that's inconsistent with the requirements of the failed
+ * group.
+ */
+
+/*
+ * The "Multi-function Pins Mapping and Control" table in the SoC datasheet
+ * references registers by the device/offset mnemonic. The register macros
+ * below are named the same way to ease transcription and verification (as
+ * opposed to naming them e.g. PINMUX_CTRL_[0-9]). Further, signal expressions
+ * reference registers beyond those dedicated to pinmux, such as the system

A subset of the pins and functions are exposed. The selection of
functions and pins is driven by the development of OpenBMC[1] on the
AST2400 SoC, particularly around booting the OpenPOWER Palmetto
development machine.

From: Joel Stanley <joel@jms.id.au>

The Aspeed SoCs contain GPIOs banked by letter, where each bank contains
8 pins. The GPIO banks are then grouped in sets of four in the register
layout.

The implementation exposes multiple banks through the one driver and
requests and releases pins via the pinctrl subsystem. The hardware
supports generation of interrupts from all GPIO-capable pins.

A number of hardware features are not yet supported: Configuration of
interrupt direction (ARM or LPC), debouncing, and WDT reset tolerance
for output ports.

I guess some device tree maintainer or SoC tree should merge this patch.
If you think it is proper to apply in the pinctrl or gpio tree, tell me.

I think it's best to take this through arm-soc to avoid conflicts in
case we add other lines too.

Maybe add a global regex instead of a growing list of file names though.

Patch applied! It's not getting better than this through iteration, it is better
to get the system up and develop inside the mainline tree from now on.

I dropped this hunk of the patch, because:

(A) I didn't merge the glob patch and
(B) the glob covers this driver too, it is a tautology/truism

Patch applied to the GPIO tree.

As there are no compile-time dependencies between the
pin control and GPIO drivers I choose to merge the pinctrl
stuff through the pinctrl tree and the GPIO stuff through the GPIO
tree.

Linus Walleij

I used get_maintainer.pl on the series to construct the CC, but Lee
wasn't listed in the output. I'll poke further at MAINTAINERs in the
future to make sure I have coverage for affected subsystems.

Okay

> (B) the glob covers this driver too, it is a tautology/truism

So experimenting with this my results don't agree - without the hunk
get_maintainer.pl falls back to git and s-o-bs to pick up the Aspeed
maintainer:

With the hunk:

    $ ./scripts/get_maintainer.pl drivers/pinctrl/aspeed/pinctrl-aspeed.c
    Joel Stanley <    joel@jms.id.au    > (maintainer:ARM/ASPEED MACHINE SUPPORT)
    Linus Walleij <    linus.walleij@linaro.org    > (maintainer:PIN CONTROL SUBSYSTEM)
    linux-gpio@vger.kernel.org     (open list:PIN CONTROL SUBSYSTEM)

Without the hunk:

    $ ./scripts/get_maintainer.pl drivers/pinctrl/aspeed/pinctrl-aspeed.c
    Linus Walleij <    linus.walleij@linaro.org    > (maintainer:PIN CONTROL SUBSYSTEM)
    Joel Stanley <    joel@jms.id.au    > (commit_signer:1/1=100%)
    Andrew Jeffery <    andrew@aj.id.au    > (commit_signer:1/1=100%,authored:1/1=100%,added_lines:498/498=100%)
    linux-gpio@vger.kernel.org     (open list:PIN CONTROL SUBSYSTEM)
    linux-kernel@vger.kernel.org     (open list)

So removing git as a fallback Joel isn't listed as a relevant
maintainer despite the glob:

    $ ./scripts/get_maintainer.pl --no-git-fallback drivers/pinctrl/aspeed/pinctrl-aspeed.c
    Linus Walleij <    linus.walleij@linaro.org    > (maintainer:PIN CONTROL SUBSYSTEM)
    linux-gpio@vger.kernel.org     (open list:PIN CONTROL SUBSYSTEM)
    linux-kernel@vger.kernel.org     (open list)

I expect it's the case that the globbing doesn't match directories like
the hunk in question does with its trailing '/'. However, given we will
likely do something different in light of Arnd's suggestion it probably
doesn't matter.

Cheers,

Andrew
