Subject: [PATCH v3 01/12] dt-bindings: media: sunxi-ir: add A31 compatible
Date: Tue, 28 May 2019 18:14:29 +0200 [thread overview]
Message-ID: <20190528161440.27172-2-peron.clem@gmail.com> (raw)
In-Reply-To: <20190528161440.27172-1-peron.clem@gmail.com>
Allwinner A31 has introduced a new memory mapping and a
reset line.
The difference in memory mapping are :
- In the configure register there is a new sample bit
and Allwinner has introduced the active threshold feature.
- In the status register a new STAT bit is present.
Note: CGPO and DRQ_EN bits are removed on A31 but present on A13
and on new SoCs like A64/H6.
This is actually not an issue as these bits are togglable and new
SoCs have a dedicated bindings.
Introduce this bindings to make a difference since this generation.
And declare the reset line required since A31.

Device-Tree bindings for SUNXI IR controller found in sunXi SoC family
Required properties:
-- compatible : "allwinner,sun4i-a10-ir" or "allwinner,sun5i-a13-ir"
+- compatible :
+ "allwinner,sun4i-a10-ir"
+ "allwinner,sun5i-a13-ir"
+ "allwinner,sun6i-a31-ir"
- clocks : list of clock specifiers, corresponding to
entries in clock-names property;
- clock-names : should contain "apb" and "ir" entries;
- interrupts : should contain IR IRQ number;
- reg : should contain IO map address for IR.
+Required properties since A31:
+- resets : phandle + reset specifier pair
+
Optional properties:
- linux,rc-map-name: see rc.txt file in the same directory.
-- resets : phandle + reset specifier pair
- clock-frequency : IR Receiver clock frequency, in Hertz. Defaults to 8 MHz
if missing.
