[PATCH v3 1/4] dt-bindings: pinctrl: tegra: Convert to json-schema

Thierry Reding
2022-11-04T14:26:38Z

From: Thierry Reding <treding@nvidia.com>

Convert the NVIDIA Tegra pinmux controller bindings from the free-form
text format to json-schema.

Signed-off-by: Thierry Reding <treding@nvidia.com>
---
Changes in v3:
- add missing "type: object" to patternProperties definitions
- restructure common bindings according to Rob's comments

Changes in v2:
- wrap lines at 80 characters instead of the standard 100 characters in Linux
- use GPL-2.0-only instead of GPL-2.0+ license for DT bindings
- reorder additionalProperties for better readability
- move common definitions into a shared schema
- remove consumer snippets from examples

+description: |
+ 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".
+
+ Tegra's 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, tristate, drive strength,
+ etc.
+
+ 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 or tristate parameter. For this
+ reason, even seemingly boolean values are actually tristates in this
+ binding: unspecified, off, or on. Unspecified is represented as an absent
+ property, and off/on are represented as integer values 0 and 1.
+
+ Note that many of these properties are only valid for certain specific pins
+ or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+ details regarding which groups support which functionality. The Linux
+ pinctrl driver may also be a useful reference, since it consolidates,
+ disambiguates, and corrects data from all those sources.

-NVIDIA Tegra114 pinmux controller
-
-The Tegra114 pinctrl binding is very similar to the Tegra20 and Tegra30
-pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
-nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
-a baseline, and only documents the differences between the two bindings.
-
-Required properties:
-- compatible: "nvidia,tegra114-pinmux"
-- reg: Should contain the register physical address and length for each of
- the pad control and mux registers. The first bank of address must be the
- driver strength pad control register address and second bank address must
- be pinmux register address.
-
-Tegra114 adds the following optional properties for pin configuration subnodes:
-- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
-- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
- until reset. 0: no, 1: yes.
-- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
-- nvidia,rcv-sel: Integer. Select VIL/VIH receivers. 0: normal, 1: high.
-- nvidia,drive-type: Integer. Valid range 0...3.
-
-As with Tegra20 and Terga30, see the Tegra TRM for complete details regarding
-which groups support which functionality.
-
-Valid values for pin and group names are:
-
- per-pin mux groups:
-
- These all support nvidia,function, nvidia,tristate, nvidia,pull,
- nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
- nvidia,io-reset and nvidia,rcv-sel.

-NVIDIA Tegra124 pinmux controller
-
-The Tegra124 pinctrl binding is very similar to the Tegra20 and Tegra30
-pinctrl binding, as described in nvidia,tegra20-pinmux.txt and
-nvidia,tegra30-pinmux.txt. In fact, this document assumes that binding as
-a baseline, and only documents the differences between the two bindings.
-
-Required properties:
-- compatible: For Tegra124, must contain "nvidia,tegra124-pinmux". For
- Tegra132, must contain '"nvidia,tegra132-pinmux", "nvidia-tegra124-pinmux"'.
-- reg: Should contain a list of base address and size pairs for:
- -- first entry - the drive strength and pad control registers.
- -- second entry - the pinmux registers
- -- third entry - the MIPI_PAD_CTRL register
-
-Tegra124 adds the following optional properties for pin configuration subnodes.
-The macros for options are defined in the
- include/dt-binding/pinctrl/pinctrl-tegra.h.
-- nvidia,enable-input: Integer. Enable the pin's input path.
- enable :TEGRA_PIN_ENABLE and
- disable or output only: TEGRA_PIN_DISABLE.
-- nvidia,open-drain: Integer.
- enable: TEGRA_PIN_ENABLE.
- disable: TEGRA_PIN_DISABLE.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
- until reset.
- enable: TEGRA_PIN_ENABLE.
- disable: TEGRA_PIN_DISABLE.
-- nvidia,io-reset: Integer. Reset the IO path.
- enable: TEGRA_PIN_ENABLE.
- disable: TEGRA_PIN_DISABLE.
-- nvidia,rcv-sel: Integer. Select VIL/VIH receivers.
- normal: TEGRA_PIN_DISABLE
- high: TEGRA_PIN_ENABLE
-
-Please refer the Tegra TRM for complete details regarding which groups
-support which functionality.
-
-Valid values for pin and group names are:
-
- per-pin mux groups:
-
- These all support nvidia,function, nvidia,tristate, nvidia,pull,
- nvidia,enable-input. Some support nvidia,lock nvidia,open-drain,
- nvidia,io-reset and nvidia,rcv-sel.

-mux function to select on those pin(s)/group(s), and various pin configuration
-parameters, such as pull-up, tristate, drive strength, etc.
-
-See the TRM to determine which properties and values apply to each pin/group.
-Macro values for property values are defined in
-include/dt-binding/pinctrl/pinctrl-tegra.h.
-
-Required subnode-properties:
-- nvidia,pins : An array of strings. Each string contains the name of a pin or
- group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- nvidia,function: A string containing the name of the function to mux to the
- pin or group.
-- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
- 0: none, 1: down, 2: up.
-- nvidia,tristate: Integer.
- 0: drive, 1: tristate.
-- nvidia,enable-input: Integer. Enable the pin's input path.
- enable :TEGRA_PIN_ENABLE and
- disable or output only: TEGRA_PIN_DISABLE.
-- nvidia,open-drain: Integer.
- enable: TEGRA_PIN_ENABLE.

- enable: TEGRA_PIN_ENABLE.
- disable: TEGRA_PIN_DISABLE.
-- nvidia,io-hv: Integer. Select high-voltage receivers.
- normal: TEGRA_PIN_DISABLE
- high: TEGRA_PIN_ENABLE
-- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
- normal: TEGRA_PIN_DISABLE
- high: TEGRA_PIN_ENABLE
-- nvidia,drive-type: Integer. Valid range 0...3.
-- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
- The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
- Tegra TRM.
-- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
- The range of valid values depends on the pingroup. See "CAL_DRVUP" in the

-
-Valid values for pin and group names (nvidia,pin) are:
-
- These correspond to Tegra PADCTL_* (pinmux) registers.
-
- Mux groups:
-
- These correspond to Tegra PADCTL_* (pinmux) registers. Any property
- that exists in those registers may be set for the following pin names.
-
- pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
-
- Drive groups:
-
- These registers controls a single pin for which a mux group exists.
- See the list above for the pin name to use when configuring the pinmux.
-
- pex_l5_clkreq_n_pgg0, pex_l5_rst_n_pgg1
-
-Valid values for nvidia,functions are:
-
- pe5
-
-Power Domain:
- pex_l5_clkreq_n_pgg0 and pex_l5_rst_n_pgg1 are part of PCIE C5 power

-NVIDIA Tegra20 pinmux controller
-
-Required properties:
-- compatible: "nvidia,tegra20-pinmux"
-- reg: Should contain the register physical address and length for each of
- the tri-state, mux, pull-up/down, and pad control register sets.
-
-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".
-
-Tegra's 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, tristate, drive strength, etc.
-
-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 or tristate parameter. For this
-reason, even seemingly boolean values are actually tristates in this binding:
-unspecified, off, or on. Unspecified is represented as an absent property,
-and off/on are represented as integer values 0 and 1.
-
-Required subnode-properties:
-- nvidia,pins : An array of strings. Each string contains the name of a pin or
- group. Valid values for these names are listed below.
-
-Optional subnode-properties:
-- nvidia,function: A string containing the name of the function to mux to the
- pin or group. Valid values for function names are listed below. See the Tegra
- TRM to determine which are valid for each pin or group.
-- nvidia,pull: Integer, representing the pull-down/up to apply to the pin.
- 0: none, 1: down, 2: up.
-- nvidia,tristate: Integer.
- 0: drive, 1: tristate.
-- nvidia,high-speed-mode: Integer. Enable high speed mode the pins.
- 0: no, 1: yes.
-- nvidia,schmitt: Integer. Enables Schmitt Trigger on the input.
- 0: no, 1: yes.
-- nvidia,low-power-mode: Integer. Valid values 0-3. 0 is least power, 3 is
- most power. Controls the drive power or current. See "Low Power Mode"
- or "LPMD1" and "LPMD0" in the Tegra TRM.
-- nvidia,pull-down-strength: Integer. Controls drive strength. 0 is weakest.
- The range of valid values depends on the pingroup. See "CAL_DRVDN" in the
- Tegra TRM.
-- nvidia,pull-up-strength: Integer. Controls drive strength. 0 is weakest.
- The range of valid values depends on the pingroup. See "CAL_DRVUP" in the
- Tegra TRM.
-- nvidia,slew-rate-rising: Integer. Controls rising signal slew rate. 0 is
- fastest. The range of valid values depends on the pingroup. See
- "DRVDN_SLWR" in the Tegra TRM.
-- nvidia,slew-rate-falling: Integer. Controls falling signal slew rate. 0 is
- fastest. The range of valid values depends on the pingroup. See
- "DRVUP_SLWF" in the Tegra TRM.
-
-Note that many of these properties are only valid for certain specific pins
-or groups. See the Tegra TRM and various pinmux spreadsheets for complete
-details regarding which groups support which functionality. The Linux pinctrl
-driver may also be a useful reference, since it consolidates, disambiguates,
-and corrects data from all those sources.

-NVIDIA Tegra30 pinmux controller
-
-The Tegra30 pinctrl binding is very similar to the Tegra20 pinctrl binding,
-as described in nvidia,tegra20-pinmux.txt. In fact, this document assumes
-that binding as a baseline, and only documents the differences between the
-two bindings.
-
-Required properties:
-- compatible: "nvidia,tegra30-pinmux"
-- reg: Should contain the register physical address and length for each of
- the pad control and mux registers.
-
-Tegra30 adds the following optional properties for pin configuration subnodes:
-- nvidia,enable-input: Integer. Enable the pin's input path. 0: no, 1: yes.
-- nvidia,open-drain: Integer. Enable open drain mode. 0: no, 1: yes.
-- nvidia,lock: Integer. Lock the pin configuration against further changes
- until reset. 0: no, 1: yes.
-- nvidia,io-reset: Integer. Reset the IO path. 0: no, 1: yes.
-
-As with Tegra20, see the Tegra TRM for complete details regarding which groups
-support which functionality.
-
-Valid values for pin and group names are:
-
- per-pin mux groups:
-
- These all support nvidia,function, nvidia,tristate, nvidia,pull,
- nvidia,enable-input, nvidia,lock. Some support nvidia,open-drain,
- nvidia,io-reset.
