Hello, The following series adds support for the soc driver to route audio (PCM stream) to the vibra ports of the twl6040. We have ALSA controls for the vibra source selection (PDM, or Input/FF). The route can not be changed from Input/FF to PDM during ongoing effect coming from Input/FF. The Input/FF driver can not execute new effect, while the vibra source is configured to be PDM. TO get things working in legacy mode the omap-mcpdm, and twl6040 soc codec driver's channel count needed to be fixed. To minimize the need for reads through the I2C bus, the MFD driver will cache the vibra control registers. With this series we can route PCM audio to drive the twl6040 vibra output. In order to that we need to play 5 channel audio, and place the vibra sample at the 5th channel. This will change with ABE support (change == simplified). The series depends on the previous two from me: ASoC: twl6040: Cleanups and fixes ASoC: omap-mcpdm/twl6040: Offset cancellation Regards, Peter PS: Samuel, Dmitry, Liam: will it be possible to take this through Liam (via audio), since we are going to have dependencies coming via audio. --- Peter Ujfalusi (8): Input: twl6040: Simplify vibra regsiter definitions MFD: twl6040: Cache the vibra control registers MFD: twl6040: function to query the vibra status for clients Input: twl6040-vibra: Check the selected path for vibra ASoC: twl6040: Fix the number of channels for vibra ASoC: twl6040: Correct supported number of playback channels ASoC: omap-mcpdm: Correct the supported number of channels ASoC: twl6040: Support for vibra output paths drivers/input/misc/twl6040-vibra.c | 19 ++++++--- drivers/mfd/twl6040-core.c | 31 ++++++++++++-- include/linux/mfd/twl6040.h | 24 +++++------ sound/soc/codecs/twl6040.c | 78 ++++++++++++++++++++++++++++++++++- sound/soc/omap/omap-mcpdm.c | 14 ++++--- 5 files changed, 134 insertions(+), 32 deletions(-) -- 1.7.6.1 -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
