[alsa-devel] [PATCH] ASoC: zoom2: Remove HS mux GPIO handling to avoid kernel crash due to BUG_ON()
by Peter Ujfalusi 03 Dec '12

The machine driver try to use GPIO15 of twl4030 for HS MUX which supposed to select between TWL's HSOL/R and tlv320aic3254's HPL/R. The TWL's GPIO allocated dynamically so the (OMAP_MAX_GPIO_LINES + 15) is no longer valid GPIO number causing a kernel crash due to BUG_ON() Also the current machine driver supports only TWL audio currently: there is no need to control the GPIO. Signed-off-by: Peter Ujfalusi <peter.ujfalusi(a)ti.com> --- Hi Liam, Mark, I just got one zoom2 board and this patch is needed to get the board booting when audio is enabled. For 3.9 I will convert the machine driver to platform device/driver, but to get 3.8 kernel booting this patch is needed.

[alsa-devel] [PATCH 1/1] ASoC: wm9090: Use devm_regmap_init_i2c()

[alsa-devel] Preliminary driver for RME MADI FX
by Adrian Knoth 01 Dec '12

01 Dec '12

Hi! I've been working on a driver for the new 390 channels RME MADI FX. For those who are interested, I've made the source available here: https://github.com/adiknoth/madifx As mentioned there, I only had remote access, so not all possible hardware configurations have been tested. This might change next year, until then, consider everything as "coincidentally working" ;) Most importantly, the userspace API isn't stable, yet, since we still have to develop new tools for metering and mixer adjustments. If we exclude this API (the ioctls) for now, it is moderately safe to go mainline, though we definitely lack decent test coverage. ALSA devs: Feel free to demand any changes that are required for mainline inclusion. The github repo is meant to serve as an incubator from which we'll eventually derive the final kernel patch. Cheers
