| Message-ID | <tNWn7-2Pu-3@gated-at.bofh.it> |
The Cirrus Logic CS47L35, CS47L85, CS47L90/91 codecs are complex audio SoC devices. In addition to the core audio capability they have onboard GPIO, regulators, DSPs and interrupt controller and a large register map space accessed over SPI or I2C. This family of codecs is based around common IP blocks and they are managed by a set of common drivers referred to as "Madera". Summary of main changes since V1: - Removed child DT nodes and of_compatibles to make the DT flat - Fixed review comments on irqchip driver - Used new field names for IRQ1_STATUS_33 register - Moved the gpio driver bindings into the main MFD binding doc - Some code improvements to the pinctrl driver Richard Fitzgerald (17): mfd: madera: Add register definitions for Cirrus Logic Madera codecs mfd: madera: Add DT bindings for Cirrus Logic Madera codecs mfd: madera: Add common support for Cirrus Logic Madera codecs mfd: madera: Register map tables for Cirrus Logic CS47L35 mfd: madera: Register map tables for Cirrus Logic CS47L85 mfd: madera: Register map tables for Cirrus Logic CS47L90/91 regulator: arizona-micsupp: Add support for Cirrus Logic Madera codecs regulator: arizona-ldo1: Add support for Cirrus Logic Madera codecs irqchip: Add driver for Cirrus Logic Madera codecs pinctrl: madera: Add DT bindings for Cirrus Logic Madera codecs pinctrl: madera: Add driver for Cirrus Logic Madera codecs gpio: madera: Support Cirrus Logic Madera class codecs ASoC: madera: Add DT bindings for Cirrus Logic Madera codecs ASoC: madera: Add common support for Cirrus Logic Madera codecs ASoC: cs47l35: Add codec driver for Cirrus Logic CS47L35 ASoC: cs47l85: Add codec driver for Cirrus Logic CS47L85 ASoC: cs47l90: Add codec driver for Cirrus Logic CS47L90 Documentation/devicetree/bindings/mfd/madera.txt | 102 + .../bindings/pinctrl/cirrus,madera-pinctrl.txt | 99 + .../bindings/regulator/arizona-regulator.txt | 3 +- Documentation/devicetree/bindings/sound/madera.txt | 67 + MAINTAINERS | 23 + drivers/gpio/Kconfig | 6 + drivers/gpio/Makefile | 1 + drivers/gpio/gpio-madera.c | 196 + drivers/irqchip/Kconfig | 3 + drivers/irqchip/Makefile | 1 + drivers/irqchip/irq-madera.c | 301 + drivers/mfd/Kconfig | 46 + drivers/mfd/Makefile | 13 + drivers/mfd/cs47l35-tables.c | 1688 ++++ drivers/mfd/cs47l85-tables.c | 3169 +++++++ drivers/mfd/cs47l90-tables.c | 2830 +++++++ drivers/mfd/madera-core.c | 632 ++ drivers/mfd/madera-i2c.c | 131 + drivers/mfd/madera-spi.c | 132 + drivers/mfd/madera.h | 52 + drivers/pinctrl/Kconfig | 1 + drivers/pinctrl/Makefile | 1 + drivers/pinctrl/cirrus/Kconfig | 15 + drivers/pinctrl/cirrus/Makefile | 11 + drivers/pinctrl/cirrus/pinctrl-cs47l35.c | 46 + drivers/pinctrl/cirrus/pinctrl-cs47l85.c | 60 + drivers/pinctrl/cirrus/pinctrl-cs47l90.c | 58 + drivers/pinctrl/cirrus/pinctrl-madera.c | 1074 +++ drivers/pinctrl/cirrus/pinctrl-madera.h | 40 + drivers/regulator/Kconfig | 15 +- drivers/regulator/arizona-ldo1.c | 82 +- drivers/regulator/arizona-micsupp.c | 71 +- include/dt-bindings/sound/madera.h | 27 + include/linux/irqchip/irq-madera-pdata.h | 23 + include/linux/irqchip/irq-madera.h | 96 + include/linux/mfd/madera/core.h | 180 + include/linux/mfd/madera/pdata.h | 61 + include/linux/mfd/madera/registers.h | 8832 ++++++++++++++++++++ include/sound/madera-pdata.h | 61 + sound/soc/codecs/Kconfig | 23 + sound/soc/codecs/Makefile | 8 + sound/soc/codecs/cs47l35.c | 1747 ++++ sound/soc/codecs/cs47l85.c | 2706 ++++++ sound/soc/codecs/cs47l90.c | 2645 ++++++ sound/soc/codecs/madera.c | 4430 ++++++++++ sound/soc/codecs/madera.h | 470 ++ 46 files changed, 32268 insertions(+), 10 deletions(-) create mode 100644 Documentation/devicetree/bindings/mfd/madera.txt create mode 100644 Documentation/devicetree/bindings/pinctrl/cirrus,madera-pinctrl.txt create mode 100644 Documentation/devicetree/bindings/sound/madera.txt create mode 100644 drivers/gpio/gpio-madera.c create mode 100644 drivers/irqchip/irq-madera.c create mode 100644 drivers/mfd/cs47l35-tables.c create mode 100644 drivers/mfd/cs47l85-tables.c create mode 100644 drivers/mfd/cs47l90-tables.c create mode 100644 drivers/mfd/madera-core.c create mode 100644 drivers/mfd/madera-i2c.c create mode 100644 drivers/mfd/madera-spi.c create mode 100644 drivers/mfd/madera.h create mode 100644 drivers/pinctrl/cirrus/Kconfig create mode 100644 drivers/pinctrl/cirrus/Makefile create mode 100644 drivers/pinctrl/cirrus/pinctrl-cs47l35.c create mode 100644 drivers/pinctrl/cirrus/pinctrl-cs47l85.c create mode 100644 drivers/pinctrl/cirrus/pinctrl-cs47l90.c create mode 100644 drivers/pinctrl/cirrus/pinctrl-madera.c create mode 100644 drivers/pinctrl/cirrus/pinctrl-madera.h create mode 100644 include/dt-bindings/sound/madera.h create mode 100644 include/linux/irqchip/irq-madera-pdata.h create mode 100644 include/linux/irqchip/irq-madera.h create mode 100644 include/linux/mfd/madera/core.h create mode 100644 include/linux/mfd/madera/pdata.h create mode 100644 include/linux/mfd/madera/registers.h create mode 100644 include/sound/madera-pdata.h create mode 100644 sound/soc/codecs/cs47l35.c create mode 100644 sound/soc/codecs/cs47l85.c create mode 100644 sound/soc/codecs/cs47l90.c create mode 100644 sound/soc/codecs/madera.c create mode 100644 sound/soc/codecs/madera.h -- 1.9.1

This is the binding description of the pinctrl driver for Cirru Logic
Madera codecs. The binding uses the generic pinctrl binding so the main
purpose here is to describe the device-specific names for groups and
functions.

+Cirrus Logic Madera class audio codecs pinctrl driver
+
+The Cirrus Logic Madera codecs provide a number of GPIO functions for
+interfacing to external hardware and to provide logic outputs to other devices.
+Certain groups of GPIO pins also have an alternate function, normally as an
+audio interface.
+
+The set of available GPIOs, functions and alternate function groups differs
+between codecs so refer to the datasheet for the codec for further information
+on what is supported on that device.
+
+The properties for this driver exist within the parent MFD driver node.
+
+See also
+ the core bindings for the parent MFD driver:
+ Documentation/devicetree/bindings/mfd/madera.txt
+
+ the generic pinmix bindings:
+ Documentation/devicetree/bindings/pinctrl/pinctrl-bindings.txt
+
+Required properties of parent mfd node:
+ - pinctrl-names : must be "default"
+ - pinctrl-0 : a phandle to the node containing the subnodes containing default
+ configurations
+
+Required subnodes:
+ One subnode is required to contain the default settings. It contains an
+ arbitrary number of configuration subnodes, one for each group or pin
+ configuration you want to apply as a default.
+
+Required properties of configuration subnodes:
+ - groups : name of one pin group to configure. One of:
+ aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,
+ dmic4, dmic5, dmic6,
+ gpio1, gpio2, ..., gpio40
+ The gpioN groups select the single pin of this name for configuration
+
+Optional properties of configuration subnodes:
+ Any configuration option not explicitly listed in the dts will be left at
+ chip default setting.
+
+ - function : name of function to assign to this group. One of:
+ aif1, aif2, aif3, aif4, mif1, mif2, mif3, pdmspk1, pdmspk2,
+ dmic3, dmic4, dmic5, dmic6,
+ io, dsp-gpio, irq1, irq2,

+ log6-fifo-ne, log7-fifo-ne, log8-fifo-ne,
+
+ - bias-disable : disable pull-up and pull-down
+ - bias-bus-hold : enable buskeeper
+ - bias-pull-up : output is pulled-up
+ - bias-pull-down : output is pulled-down
+ - drive-push-pull : CMOS output
+ - drive-open-drain : open-drain output
+ - drive-strength : drive strength in mA. Valid values are 4 or 8
+ - input-schmitt-enable : enable schmitt-trigger mode
+ - input-schmitt-disable : disable schmitt-trigger mode
+ - input-debounce : A value of 0 disables debounce, a value !=0 enables
+ debounce
+ - output-low : set the pin to output mode with low level
+ - output-high : set the pin to output mode with high level
+
+Example:
+
+cs47l85@0 {
+ compatible = "cirrus,cs47l85";
+
+ pinctrl-names = "default";
+ pinctrl-0 = <&cs47l85_defaults>;

| Subject | [PATCH v3 09/17] irqchip: Add driver for Cirrus Logic Madera codecs |
| Message-ID | <tNWn8-2Pu-33@gated-at.bofh.it> |
| In reply to | #1656322 |
The Cirrus Logic Madera codecs (Cirrus Logic CS47L35/85/90/91 and WM1840)
are highly complex devices containing up to 7 programmable DSPs and many
other internal sources of interrupts plus a number of GPIOs that can be
used as interrupt inputs. The large number (>150) of internal interrupt
sources are managed by an on-board interrupt controller.
This driver provides the handling for the interrupt controller. As the
codec is accessed via regmap, we can make use of the generic IRQ
functionality from regmap to do most of the work. Only around half of
the possible interrupt source are currently of interest from the driver
so only this subset is defined. Others can be added in future if needed.
The KConfig options are not user-configurable because this driver is
mandatory so is automatically included when the parent MFD driver is
selected.

Changes since V2:
- Used a macro to construct the regmap interrupt table
- Added kerneldoc comment to pdata header
- Fixed minor style issues

| Subject | [PATCH v3 02/17] mfd: madera: Add DT bindings for Cirrus Logic Madera codecs |
| Message-ID | <tNWn9-2Pu-59@gated-at.bofh.it> |
| In reply to | #1656322 |
Specification of the bindings for the parent MFD driver component
of the Cirrus Logic Madera codec drivers.
Note that although the interrupt controller and GPIO are child
drivers their required bindings are trivial, mandatory, and exist
within the parent MFD node so are documented here.
Signed-off-by: Richard Fitzgerald <rf@opensource.wolfsonmicro.com>

Changes since V2:
- Moved the gpio driver bindings into the main MFD binding doc

+
+See also the child driver bindings in:
+bindings/pinctrl/cirrus,madera-pinctrl.txt
+bindings/regulator/arizona-regulator.txt
+bindings/sound/madera.txt
+
+Required properties:
+
+ - compatible : One of the following chip-specific strings:
+ "cirrus,cs47l35"
+ "cirrus,cs47l85"
+ "cirrus,cs47l90"
+ "cirrus,cs47l91"
+ "cirrus,wm1840"
+
+ - reg : I2C slave address when connected using I2C, chip select number when
+ using SPI.
+
+ - DCVDD-supply : Power supply for the device as defined in
+ bindings/regulator/regulator.txt
+ Mandatory on CS47L35, CS47L90, CS47L91
+ Optional on CS47L85, WM1840
+
+ - AVDD-supply, DBVDD1-supply, DBVDD2-supply, CPVDD1-supply, CPVDD2-supply :
+ Power supplies for the device
+
+ - DBVDD3-supply, DBVDD4-supply : Power supplies for the device
+ (CS47L85, CS47L90, CS47L91, WM1840)
+
+ - SPKVDDL-supply, SPKVDDR-supply : Power supplies for the device
+ (CS47L85, WM1840)
+
+ - SPKVDD-supply : Power supply for the device
+ (CS47L35)
+
+ - interrupt-controller : Indicates that this device is an interrupt controller
+
+ - #interrupt-cells: the number of cells to describe an IRQ, must be 2.
+ The first cell is the IRQ number.
+ The second cell is the flags, encoded as the trigger masks from
+ bindings/interrupt-controller/interrupts.txt
+
+ - gpio-controller : Indicates this device is a GPIO controller.
+
+ - #gpio-cells : Must be 2. The first cell is the pin number. The second cell
+ is reserved for future use and must be zero
+
+ - interrupt-parent : The parent interrupt controller.
+
+ - interrupts : The interrupt line the /IRQ signal for the device is
+ connected to.
+
+Optional properties:
+
+ - MICVDD-supply : Power supply, only need to be specified if
+ powered externally
+
+ - reset-gpios : One entry specifying the GPIO controlling /RESET.
+ As defined in bindings/gpio.txt.
+ Although optional, it is strongly recommended to use a hardware reset
+
+ - MICBIASx : Initial data for the MICBIAS regulators, as covered in
+ Documentation/devicetree/bindings/regulator/regulator.txt.
+ One for each MICBIAS generator (MICBIAS1, MICBIAS2, ...)
+ (all codecs)
+
+ One for each output pin (MICBIAS1A, MIBCIAS1B, MICBIAS2A, ...)
+ (all except CS47L85, WM1840)
+
+ The following following additional property is supported for the generator
+ nodes:
+ - cirrus,ext-cap : Set to 1 if the MICBIAS has external decoupling
+ capacitors attached.
+
+Optional child nodes:
+ micvdd : Node containing initialization data for the micvdd regulator
+ See bindings/regulator/arizona-regulator.txt
+
+ ldo1 : Node containing initialization data for the LDO1 regulator
+ See bindings/regulator/arizona-regulator.txt
