The headphone lines are multiplexed with the debug console. The headphone and mic detect lines of the A64 are connected properly, but AFAIK currently unsupported by the driver. Signed-off-by: Harald Geyer <harald@ccbib.org> --- Hi all, a couple of issues make this patch RFC: hpvcc-supply vs. cpvdd-supply: On the A64 manual the pin is called CPVDD and the binding documents requires a cpvdd-supply property. However in the actual driver and devicetrees so far hpvcc-supply is used. This is a very new binding, so we have the luxury to decide either way, I think. Any input from the devicetree maintainers would be appreciated. debug console multiplexing: Olimex have a userspace script that controls gpio PL9 during boot, to select between HP and serial console. I guess this is not acceptable for mainline. The best solution I can see is to switch the HP jack from serial console to audio once the audio drivers load. With this people can still capture the bootlogs but everybody gets audio once the system is up and switching back to console output is as simple as unloading the audio drivers. However the current implementation with a pinctrl group doesn't work: The audio card device correctly claims the pin (ie I can't export the gpio in sysfs anymore), but the pinctrl driver doesn't set the pin to output. Testing: I don't have a headset with combo connector, so I could only test the headphones output, but not the headset mic. If somebody happens to have a TERES-I and a suitable headset, testing this would be nice.
