Some features has been updated or added to the low-power timer: - new capture compare channels - up to two PWM channels - PWM input capture - peripheral interconnect in stm32mp25 has been updated (new triggers). - registers/bits has been added or revisited (IER access). So introduce a new compatible to handle this diversity. Signed-off-by: Fabrice Gasnier --- Changes in V3: - Fix yaml indentation issue found by Rob's bot Changes in V2: - Use fallback compatibles, along with stm32mp25 specific compatible - trigger identifier can be up to 4 (e.g. from LPTIM1..5) --- .../bindings/mfd/st,stm32-lptimer.yaml | 40 ++++++++++++++++--- 1 file changed, 34 insertions(+), 6 deletions(-) diff --git a/Documentation/devicetree/bindings/mfd/st,stm32-lptimer.yaml b/Documentation/devicetree/bindings/mfd/st,stm32-lptimer.yaml index d41308856408..4eabafb8079d 100644 --- a/Documentation/devicetree/bindings/mfd/st,stm32-lptimer.yaml +++ b/Documentation/devicetree/bindings/mfd/st,stm32-lptimer.yaml @@ -21,7 +21,12 @@ maintainers: properties: compatible: - const: st,stm32-lptimer + oneOf: + - items: + - const: st,stm32mp25-lptimer + - const: st,stm32-lptimer + - items: + - const: st,stm32-lptimer reg: maxItems: 1 @@ -48,13 +53,21 @@ properties: minItems: 1 maxItems: 2 + power-domains: + maxItems: 1 + pwm: type: object additionalProperties: false properties: compatible: - const: st,stm32-pwm-lp + oneOf: + - items: + - const: st,stm32mp25-pwm-lp + - const: st,stm32-pwm-lp + - items: + - const: st,stm32-pwm-lp "#pwm-cells": const: 3 @@ -69,7 +82,12 @@ properties: properties: compatible: - const: st,stm32-lptimer-counter + oneOf: + - items: + - const: st,stm32mp25-lptimer-counter + - const: st,stm32-lptimer-counter + - items: + - const: st,stm32-lptimer-counter required: - compatible @@ -80,7 +98,12 @@ properties: properties: compatible: - const: st,stm32-lptimer-timer + oneOf: + - items: + - const: st,stm32mp25-lptimer-timer + - const: st,stm32-lptimer-timer + - items: + - const: st,stm32-lptimer-timer required: - compatible @@ -92,13 +115,18 @@ patternProperties: properties: compatible: - const: st,stm32-lptimer-trigger + oneOf: + - items: + - const: st,stm32mp25-lptimer-trigger + - const: st,stm32-lptimer-trigger + - items: + - const: st,stm32-lptimer-trigger reg: description: Identify trigger hardware block. items: minimum: 0 - maximum: 2 + maximum: 4 required: - compatible -- 2.25.1
