From 406dcbc55a0a20fd155be889a4a0c4b812f7c18e Mon Sep 17 00:00:00 2001 From: Hui Wang Date: Mon, 29 Apr 2019 11:44:07 +0800 Subject: [PATCH] ASoC: rt5645: Headphone Jack sense inverts on the LattePanda board The LattePanda board has a sound card chtrt5645, when there is nothing plugged in the headphone jack, the system thinks the headphone is plugged in, while we plug a headphone in the jack, the system thinks the headphone is unplugged. If adding quirk=0x21 in the module parameter, the headphone jack can work well. So let us fix it via platform_data. https://bugs.launchpad.net/bugs/182459 Signed-off-by: Hui Wang Signed-off-by: Mark Brown --- sound/soc/codecs/rt5645.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+) diff --git a/sound/soc/codecs/rt5645.c b/sound/soc/codecs/rt5645.c index f842775..cd45d41 100644 --- a/sound/soc/codecs/rt5645.c +++ b/sound/soc/codecs/rt5645.c @@ -3634,6 +3634,11 @@ static const struct rt5645_platform_data jd_mode3_platform_data = { .jd_mode = 3, }; +static const struct rt5645_platform_data lattepanda_board_platform_data = { + .jd_mode = 2, + .inv_jd1_1 = true +}; + static const struct dmi_system_id dmi_platform_data[] = { { .ident = "Chrome Buddy", @@ -3731,6 +3736,15 @@ static const struct dmi_system_id dmi_platform_data[] = { }, .driver_data = (void *)&intel_braswell_platform_data, }, + { + .ident = "LattePanda board", + .matches = { + DMI_EXACT_MATCH(DMI_BOARD_VENDOR, "AMI Corporation"), + DMI_EXACT_MATCH(DMI_BOARD_NAME, "Cherry Trail CR"), + DMI_EXACT_MATCH(DMI_BOARD_VERSION, "Default string"), + }, + .driver_data = (void *)&lattepanda_board_platform_data, + }, { } }; -- 2.7.4
