From: Hans de Goede hdegoede@redhat.com Date: Thu, 5 Jul 2018 00:59:32 +0200 Subject: [PATCH] ASoC: rt5651: Allow disabling jack-detect by calling set_jack(NULL)

Allow the machine driver to disable jack-detect over a suspend/resume by calling snd_soc_component_set_jack(NULL).

Note this renames rt5651_set_jack, where all the jack-enable work was done to rt5651_enable_jack_detect. This function can now no longer fail as it does not request the IRQ anymore. It can still be passed an invalid jack source, but that should never happen, so this is now logged and treated as no jack source.

From: Hans de Goede hdegoede@redhat.com Date: Thu, 5 Jul 2018 00:59:33 +0200 Subject: [PATCH] ASoC: rt5651: Add button press support

Enable button press detection for headsets by using the ovcd IRQ to get notified of button presses.

This is modelled after (almost exactly copied from) the button press code for the rt5640 which has identical ovcd hardware.
