ASoC: rt5640: Add jack-detect support
Add jack-detect support, loosely based on earlier work on this by: Pierre-Louis Bossart <pierre-louis.bossart@linux.intel.com> Francisco mendez <francisco.mendez@intel.com> Note getting the OVCD to work reliable was sort of finicky, so there are quite a few comments on this to hopefully avoid people breaking it in the future. This (and the follow-up button press support) has been tested on the following devices: Acer Iconia Tab 8 W1-810 Asus T100CHI Asus T100TA Asus T200TA Axxo WT1011 Chuwi Vi8 Dell Venue 8 Pro 5830 HP Pavilion X2 10-n000nd HP Stream 7 I.T. Works TW891 Lamina I8270 MSI S100 Peaq C1010 Pipo W4 PoV MobiiTAB-P800W (v2.0) Toshiba Click Mini L9W-B BugLink: https://bugzilla.kernel.org/show_bug.cgi?id=196377 Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mark Brown <broonie@kernel.org>
