[PATCH v2 5/5] media: chips-media: wave5: support Wave515 decoder

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

 



Add initial support for Wave515 multi-decoder IP. For now it is only
able to decode HEVC Main/Main10 profile videos.

This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded.
Users of the real hardware with Wave515 IP will have to
 * provide firmware specific to their SoC
 * add struct wave5_match_data like this:

	static const struct wave5_match_data platform_name_wave515_data = {
		.flags = WAVE5_IS_DEC,
		.fw_name = "cnm/wave515_platform_name_fw.bin",
	};

 * add item to wave5_dt_ids[] like this:

	{
		.compatible = "vendor,soc-wave515",
		.data = &platform_name_wave515_data,
	},

 * describe new compatible in
   Documentation/devicetree/bindings/media/cnm,wave521c.yaml
