This series expands the OMAP mcbsp driver to support changing it's DMA operating mode and smart idle mode from client drivers. It's primarily aimed at lowering the power consumption for OMAP ASoC drivers by providing methods to gate clocks on the mcbsp interface at runtime.
I've also added a patch to remove the mcbsp DMA op mode sysfs set functionality. I think DMA op mode is very specific to the mcbsp client driver _only_ and shouldn't really be changed by userspace. Please let me know if you use this feature and I'll drop this patch. Tony, can I get your ack to upstream via ALSA if it's ok Thanks Liam arch/arm/plat-omap/include/plat/mcbsp.h | 17 +++ arch/arm/plat-omap/mcbsp.c | 183 ++++++++++++++++++++++++++----- sound/soc/omap/omap-mcbsp.c | 22 ++++- sound/soc/omap/omap-mcbsp.h | 2 + 4 files changed, 194 insertions(+), 30 deletions(-) -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
