Subject[PATCH 00/11] ARM: OMAP/DTS: dra7/72-evm/beagle-x15: Audio support
Message-ID<q0UmB-SN-3@gated-at.bofh.it>
Hi,

this series will enable analog audio (via onboard aic310x codec) for dra7-evm,
dra72-evm and am57xx-beagle-x15 boards.
In these board McASP3 is connected to the codec and for the McASP3 we needed to
have the DMA crossbar in place since the request lines are not mapped by
default.

Regars,
Peter

Date2015-08-24 09:30 +0200
Subject[PATCH 09/11] ARM: DTS: dra72-evm: Audio support
Message-ID<q0UmB-SN-11@gated-at.bofh.it>
In reply to#1211853
The board uses tlv320aic3106 codec connected to McASP3. The master clock
for the codec and McASP3 is coming from ATL2.
McASP3 is the master on the I2S bus.

Subject[PATCH 08/11] ARM: DTS: dra72-evm: Add gpio hog for vin6_sel_s0 to select audio
Message-ID<q0UmC-SN-25@gated-at.bofh.it>
In reply to#1211853
The GPIO expander's p1 on i2c5 bus 0x26 address is used for selecting
between audio and VIN6 functionality. For VIN6 use an add on card is
needed while audio is present on the board itself.
Select the audio functionality over the VIN6 in the dts file.
