[alsa-devel] [PATCH 0/3] ASoC: ti: davinci-mcasp: GPIO mode support for pins
by Peter Ujfalusi 07 Jan '19

07 Jan '19

Hi, Each McASP pins can be configured individually to be used as McASP or GPIO pin. This series will allow client drivers to use pins as GPIO (optional) in case the board wired up them to be used in this mode.

[alsa-devel] Applied "ASoC: Intel: bytcr_rt5640: Add quirks for ASUS MeMO Pad 7 (ME176C)" to the asoc tree
by Mark Brown 07 Jan '19

07 Jan '19

The patch ASoC: Intel: bytcr_rt5640: Add quirks for ASUS MeMO Pad 7 (ME176C) has been applied to the asoc tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 51a13e401a83ef37aa98c049c2c30bba885676c2 Mon Sep 17 00:00:00 2001 From: Stephan Gerhold <stephan(a)gerhold.net> Date: Wed, 2 Jan 2019 20:39:08 +0100 Subject: [PATCH] ASoC: Intel: bytcr_rt5640: Add quirks for ASUS MeMO Pad 7 (ME176C) Add quirks to select the correct input map, jack-detect options and channel map to make sound work on the ASUS MeMO Pad 7 (ME176C). Note: Although sound works out of the box, jack detection currently requires overriding the ACPI DSDT table. This is necessary because the rt5640 ACPI device (10EC5640) has the wrong GPIO listed as interrupt (one of the Bluetooth GPIOs). The correct GPIO is GPO2 0x0004 (listed as the first GPIO in the Intel(R) Audio Machine Driver - AMCR0F28 device).

[alsa-devel] [RFC 0/2] conf/ucm: bytcht-es8316 support
by Hans de Goede 07 Jan '19

07 Jan '19

Hi All, Here is the UCM profile to match the kernel patches which I just submitted upstream. Note this series is RFC for now, since it depends on the name of a few controls added by the kernel series, as well as on the long_name set by the kernel series. Once the kernel series has been merged into -next, this UCM profile series can be merged as well. I will send another mail when the kernel series has been accepted. Regards, Hans
