* DT bindings for Renesas R-Car Gen3 Thermal Sensor driver
|
||||
|
||||
On R-Car Gen3 SoCs, the thermal sensor controllers (TSC) control the thermal
|
||||
sensors (THS) which are the analog circuits for measuring temperature (Tj)
|
||||
inside the LSI.
|
||||
|
||||
Required properties:
|
||||
- compatible : "renesas,<soctype>-thermal",
|
||||
Examples with soctypes are:
|
||||
- "renesas,r8a7795-thermal" (R-Car H3)
|
||||
- "renesas,r8a7796-thermal" (R-Car M3-W)
|
||||
- reg : Address ranges of the thermal registers. Each sensor
|
||||
needs one address range. Sorting must be done in
|
||||
increasing order according to datasheet, i.e.
|
||||
TSC1, TSC2, ...
|
||||
- clocks : Must contain a reference to the functional clock.
|
||||
- #thermal-sensor-cells : must be <1>.
|
||||
|
||||
Optional properties:
|
||||
|
||||
- interrupts : interrupts routed to the TSC (3 for H3 and M3-W)
|
||||
- power-domain : Must contain a reference to the power domain. This
|
||||
property is mandatory if the thermal sensor instance
|
||||
is part of a controllable power domain.
|
||||
|
||||

|

현재의 컴파일러들은 컨트롤 의존성을 이해하고 있지 않기 때문에 컨트롤 의존성은

약간 다루기 어려울 수 있습니다. 이 섹션의 목적은 여러분이 컴파일러의 무시로
|

인해 여러분의 코드가 망가지는 걸 막을 수 있도록 돕는겁니다.
|

로드-로드 컨트롤 의존성은 데이터 의존성 배리어만으로는 정확히 동작할 수가
