Hi All,
I am finished with the ASOC driver for tlvaic23b codec on osk.
I tested the playback and capture.
But have certain issue which stops me from sending the patches.
The system hangs when there is a request for mcbsp in the platform driver
of omap ie.. at
File:sound/soc/omap/omap-mcbsp.c
Function: omap_mcbsp_dai_startup
omap_mcbsp_request(mcbsp_data->bus_id);
This is executed when we do an aplay.
In the ALSA driver(sound/arm/omap/omap-alsa.c:513) the
omap_mcbsp_request() is during the boot time.
There no issues.
So during my testing of the ASOC driver i comment out
omap_mcbsp_request(mcbsp_data->bus_id); from
platform driver (sound/soc/omap/omap-mcbsp.c) and insted requested the
omap_mcbsp in my
moudule_init of machine driver(ie sound/soc/omap/osk.c).
Write which causes this hang is at
File: arch/arm/mach-omap1/mcbsp.c
Function: omap1_mcbsp_request
__raw_writew(__raw_readw(DSP_RSTCT2) | DPS_RSTCT2_PER_EN |
DSP_RSTCT2_WD_PER_EN, DSP_RSTCT2);
Anybody has some clues to fix this.
Thanks
Arun
