Subject: [PATCH v2 07/11] dt-bindings: arm: samsung: Convert Exynos PMU bindings to json-schema
Date: Sat, 7 Sep 2019 11:20:03 +0200 [thread overview]
Message-ID: <20190907092007.9946-7-krzk@kernel.org> (raw)
In-Reply-To: <20190907092007.9946-1-krzk@kernel.org>
Convert Samsung Exynos Power Management Unit (PMU) bindings to DT schema
format using json-schema.
Signed-off-by: Krzysztof Kozlowski <krzk@kernel.org>
---
Changes since v1:
1. Fix clock-names to match all elements against schema (any number of
any clkoutN values).
This currently fails:
properties:clock-names:items: {'enum': ['clkout0', 'clkout1', 'clkout2',
'clkout3', 'clkout4', 'clkout5', 'clkout6', 'clkout7', 'clkout8',
'clkout9', 'clkout10', 'clkout11', 'clkout12', 'clkout13', 'clkout14',
'clkout15', 'clkout16']} is not of type 'array
2. Add syscon reboot and poweroff nodes.

-SAMSUNG Exynos SoC series PMU Registers
-
-Properties:
- - compatible : should contain two values. First value must be one from following list:
- - "samsung,exynos3250-pmu" - for Exynos3250 SoC,
- - "samsung,exynos4210-pmu" - for Exynos4210 SoC,
- - "samsung,exynos4412-pmu" - for Exynos4412 SoC,
- - "samsung,exynos5250-pmu" - for Exynos5250 SoC,
- - "samsung,exynos5260-pmu" - for Exynos5260 SoC.
- - "samsung,exynos5410-pmu" - for Exynos5410 SoC,
- - "samsung,exynos5420-pmu" - for Exynos5420 SoC.
- - "samsung,exynos5433-pmu" - for Exynos5433 SoC.
- - "samsung,exynos7-pmu" - for Exynos7 SoC.
- second value must be always "syscon".
-
- - reg : offset and length of the register set.
-
- - #clock-cells : must be <1>, since PMU requires once cell as clock specifier.
- The single specifier cell is used as index to list of clocks
- provided by PMU, which is currently:
- 0 : SoC clock output (CLKOUT pin)
-
- - clock-names : list of clock names for particular CLKOUT mux inputs in
- following format:
- "clkoutN", where N is a decimal number corresponding to
- CLKOUT mux control bits value for given input, e.g.
- "clkout0", "clkout7", "clkout15".
-
- - clocks : list of phandles and specifiers to all input clocks listed in
- clock-names property.
-
-Optional properties:
-
-Some PMUs are capable of behaving as an interrupt controller (mostly
-to wake up a suspended PMU). In which case, they can have the
-following properties:
-
-- interrupt-controller: indicate that said PMU is an interrupt controller
-
-- #interrupt-cells: must be identical to the that of the parent interrupt
- controller.
-
-
-Optional nodes:
-
-- nodes defining the restart and poweroff syscon children
-
-
-Example :
-pmu_system_controller: system-controller@10040000 {
- compatible = "samsung,exynos5250-pmu", "syscon";
- reg = <0x10040000 0x5000>;
- interrupt-controller;
- #interrupt-cells = <3>;
- interrupt-parent = <&gic>;
- #clock-cells = <1>;
- clock-names = "clkout0", "clkout1", "clkout2", "clkout3",
- "clkout4", "clkout8", "clkout9";
- clocks = <&clock CLK_OUT_DMC>, <&clock CLK_OUT_TOP>,
- <&clock CLK_OUT_LEFTBUS>, <&clock CLK_OUT_RIGHTBUS>,
- <&clock CLK_OUT_CPU>, <&clock CLK_XXTI>,
- <&clock CLK_XUSBXTI>;
-};
-
-Example of clock consumer :
-
-usb3503: usb3503@8 {
- /* ... */
- clock-names = "refclk";
- clocks = <&pmu_system_controller 0>;
- /* ... */
-};
