[PATCH v4 01/13] dt-bindings: media: sunxi-ir: Add A31 compatible

From: Clément Péron <hidden>
Date: 2019-06-04 16:30:10
Also in: linux-devicetree, linux-media, lkml
Subsystem: media input infrastructure (v4l/dvb), open firmware and flattened device tree bindings, the rest · Maintainers: Mauro Carvalho Chehab, Rob Herring, Krzysztof Kozlowski, Conor Dooley, Linus Torvalds

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.

 		      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
