mute and standby pins are available on the codec. If they are connected, they should be managed by the driver, instead of relying on gpio hogs or on the initial state of the GPIOs. This series also includes a patch to improve the start-up time of the channels by disabling built-in DC diagnostics. Those diagnosdtics basically serve to detect : - wires shorted together - wire shorted to ground or vbat - wire disconnected This is not useful for all platforms and the addition to the startup time is quite noticeable (230ms). The diagnostics can be enabled/disabled using a dedicated ALSA control. Changes in v3: - use SOC_SINGLE_STROBE() to register the "auto diagniostics switch" control Changes in v2: - use a ALSA control to enable/disable the auto diagnostics instead of relying on a DTS property. - fixed typos - use gpios (plural) instead of gpio in the documentation of the bindings Jean-Jacques Hiblot (3): ASoC: tas6424: Add support for the standby pin ASoC: tas6424: Add support for the mute pin ASoC: tas6424: Allow disabling auto diagnostics for faster power-on .../devicetree/bindings/sound/ti,tas6424.txt | 2 + sound/soc/codecs/tas6424.c | 72 +++++++++++++++++++++- sound/soc/codecs/tas6424.h | 4 ++ 3 files changed, 75 insertions(+), 3 deletions(-) -- 2.7.4 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
