For some rk3288-based boards the analog output and the hdmi audio are plugged on the same i2s line, so we have to do the same in the driver by using a DAI link CPU to multicodecs. This configuration can be found for example on the Radxa Rock2 or the Firefly-RK3288. This commit is based on the initial work that was done by Sjoerd Simons with some improvements. Signed-off-by: Romain Perier --- Changes in v8: None Changes in v7: - No longer select SND_SOC_ES8328_I2C from kconfig (as this driver is dynamic and genric for analog outputs) Changes in v6: - Fixed bad error handling for gpios in the probe function - Replaced 'codec clock' by 'cpu clock' for set_sysclk for cpu_dai Changes in v5: - Fixed error handling for gpios in the probe function Changes in v4: - Added support for multi codecs in the asoc machine driver, so the driver matches the hw architecture (analog and hdmi audio are connected on the same i2s line) - Renamed the driver to rk3288-hdmi-analog.c - Changed some variables names due to this renaming - Changed the documentation - Added built-in support for hdmi audio in this driver - Added support for the property 'rockchip,routing' Changes in v3: - Cosmetic changes - Added missing email to MODULE_AUTHOR Changes in v2: - Fixed wrong dependencies for SND_SOC_ROCKCHIP_ES8388, SND_SOC_ROCKCHIP_I2S was selected with unmet direct dependencies .../bindings/sound/rockchip,rk3288-hdmi-analog.txt | 36 +++ sound/soc/rockchip/Kconfig | 9 + sound/soc/rockchip/Makefile | 2 + sound/soc/rockchip/rk3288_hdmi_analog.c | 299 +++++++++++++++++++++ 4 files changed, 346 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/rockchip,rk3288-hdmi-analog.txt create mode 100644 sound/soc/rockchip/rk3288_hdmi_analog.c diff --git a/Documentation/devicetree/bindings/sound/rockchip,rk3288-hdmi-analog.txt b/Documentation/devicetree/bindings/sound/rockchip,rk3288-hdmi-analog.txt new file mode 100644 index 0000000..2539e1d --- /dev/null +++ b/Documentation/devicetree/bindings/sound/rockchip,rk3288-hdmi-analog.txt @@ -0,0 +1,36 @@ +ROCKCHIP RK3288 with HDMI and analog audio + +Required properties: +- compatible: "rockchip,rk3288-hdmi-analog" +- rockchip,model: The user-visible name of this sound complex +- rockchip,i2s-controller: The phandle of the Rockchip I2S controller that's + connected to the CODEC +- rockchip,audio-codec: The phandle of the analog audio codec. +- rockchip,routing: A list of the connections between audio components. + Each entry is a pair of strings, the first being the + connection's sink, the second being the connection's + source.
