As +a result, when the overlays were modified for dynamic loading and it +was discovered that the hifiberry-dac overlay didn't work any more, the +the rpi-dac overlay was also broken. + +The failure was caused by the fact that outside a bus, device names are +constructed from the concatenation of the path elements leading to it, +so moving the codec instantiation inside /soc caused the device name +to get a "soc" added, breaking ALSA's naming. + +See: http://forum.kodi.tv/showthread.php?tid=269814&pid=2349776#pid2349776 + +Signed-off-by: Phil Elwell <phil@raspberrypi.org> +--- + arch/arm/boot/dts/overlays/rpi-dac-overlay.dts | 2 +- + 1 file changed, 1 insertion(+), 1 deletion(-) + +--- a/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts ++++ b/arch/arm/boot/dts/overlays/rpi-dac-overlay.dts +@@ -13,7 +13,7 @@ + }; + + fragment@1 { +- target = <&soc>; ++ target-path = "/"; + __overlay__ { + pcm1794a-codec { + #sound-dai-cells = <0>; |
