Subject: [PATCH v3] dt-bindings: pinctrl: Convert Amlogic Meson pinctrl binding
Date: Mon, 30 Jan 2023 22:00:24 +0100 [thread overview]
Message-ID: <285b7b4b-4fd4-be5f-266c-96b1ee6f4cbf@gmail.com> (raw)
In-Reply-To: <cb62dfc0-cb3d-beba-6d0b-8db18583dda0@gmail.com>
Convert Amlogic Meson pinctrl binding to yaml.
Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com>
---
v2:
- consider that more than one compatible can be set
- remove bus part from example
v3:
- remove minItem/maxItem properties for compatible

-Required properties for the root node:
- - compatible: one of "amlogic,meson8-cbus-pinctrl"
- "amlogic,meson8b-cbus-pinctrl"
- "amlogic,meson8m2-cbus-pinctrl"
- "amlogic,meson8-aobus-pinctrl"

- "amlogic,meson-a1-periphs-pinctrl"
- "amlogic,meson-s4-periphs-pinctrl"
- - reg: address and size of registers controlling irq functionality
-
-=== GPIO sub-nodes ===
-
-The GPIO bank for the controller is represented as a sub-node and it acts as a
-GPIO controller.
-
-Required properties for sub-nodes are:
- - reg: should contain a list of address and size, one tuple for each entry
- in reg-names.
- - reg-names: an array of strings describing the "reg" entries.
- Must contain "mux" and "gpio".
- May contain "pull", "pull-enable" and "ds" when appropriate.
- - gpio-controller: identifies the node as a gpio controller
- - #gpio-cells: must be 2
-
-=== Other sub-nodes ===
-
-Child nodes without the "gpio-controller" represent some desired
-configuration for a pin or a group. Those nodes can be pinmux nodes or
-configuration nodes.
-
-Required properties for pinmux nodes are:
- - groups: a list of pinmux groups. The list of all available groups
- depends on the SoC and can be found in driver sources.
- - function: the name of a function to activate for the specified set
- of groups. The list of all available functions depends on the SoC
- and can be found in driver sources.
-
-Required properties for configuration nodes:
- - pins: a list of pin names
-
-Configuration nodes support the following generic properties, as
-described in file pinctrl-bindings.txt:
- - "bias-disable"
- - "bias-pull-up"
- - "bias-pull-down"
- - "output-enable"
- - "output-disable"
- - "output-low"
- - "output-high"
-
-Optional properties :
- - drive-strength-microamp: Drive strength for the specified pins in uA.
- This property is only valid for G12A and newer.
-
-=== Example ===
-
- pinctrl: pinctrl@c1109880 {
- compatible = "amlogic,meson8-cbus-pinctrl";
- reg = <0xc1109880 0x10>;
- #address-cells = <1>;
- #size-cells = <1>;
- ranges;
-
- gpio: banks@c11080b0 {
- reg = <0xc11080b0 0x28>,
- <0xc11080e8 0x18>,
- <0xc1108120 0x18>,
- <0xc1108030 0x30>;
- reg-names = "mux", "pull", "pull-enable", "gpio";
- gpio-controller;
- #gpio-cells = <2>;
- };
-
- nand {
- mux {
- groups = "nand_io", "nand_io_ce0", "nand_io_ce1",
- "nand_io_rb0", "nand_ale", "nand_cle",
- "nand_wen_clk", "nand_ren_clk", "nand_dqs",
- "nand_ce2", "nand_ce3";
- function = "nand";
- };
- };
- };
