[PATCH] dt-bindings: thermal: rcar-thermal: convert bindings to json-schema

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Convert Renesas R-Car Thermal bindings documentation to json-schema.
Also name bindings documentation file according to the compat string
being documented.

As a side effect of this change all currently supported/used compat
strings are listed while no while card compat string is documented.
This, in my opinion, is desirable as only supported hardware should
be documented.

Based on v5.3-rc1
Tested using:

-Required properties:
-- compatible		: "renesas,thermal-<soctype>",
-			   "renesas,rcar-gen2-thermal" (with thermal-zone) or
-			   "renesas,rcar-thermal" (without thermal-zone) as
-                           fallback except R-Car V3M/E3/D3 and RZ/G2E.
-			  Examples with soctypes are:
-			    - "renesas,thermal-r8a73a4" (R-Mobile APE6)
-			    - "renesas,thermal-r8a7743" (RZ/G1M)
-			    - "renesas,thermal-r8a7744" (RZ/G1N)

-- reg			: Address range of the thermal registers.
-			  The 1st reg will be recognized as common register
-			  if it has "interrupts".

-Option properties:
-
-- interrupts		: If present should contain 3 interrupts for
-                          R-Car V3M/E3/D3 and RZ/G2E or 1 interrupt otherwise.
