ASoC: davinci: fix codec start and stop functions

2011-08-05T04:58:33+00:00

commit 3012f43eaf7592d8121426918e43e3b5db013aff upstream.

According to DM365 voice codec data sheet at [1], before starting
recording or playback, ADC/DAC modules should follow a reset and
enable cycle. Writing a 1 to the ADC/DAC bit in the register resets
the module and clearing the bit to 0 will enable the module. But the
driver seems to be doing the reverse of it.

ASoC: davinci: add missing break statement

2011-08-05T04:58:33+00:00

commit 82d1d521036eb3f5aae48b847f939d99a44c18bb upstream.

In davinci_vcif_trigger() function, a break() statement was missing
causing the davinci_vcif_stop() function to be called as a fallback
after calling davinci_vcif_start().

mfd: Use mfd cell platform_data for davinci cells platform bits

2011-05-26T17:45:13+00:00

With the addition of a platform device mfd_cell pointer, MFD drivers
can go back to passing platform back to their sub drivers.
This allows for an mfd_cell->mfd_data removal and thus keep the
sub drivers MFD agnostic. This is mostly needed for non MFD aware
sub drivers.

ASoC: davinci-mcasp: enable ping-pong SRAM buffers

2011-05-19T21:11:17+00:00

The davinci-i2s driver copies the platform data for playback and capture
sram sizes which is in turn used by davinci-pcm to allocate ping-pong
buffers.

Copy also the platform data in davinci-mcasp probe.

davinci-mcasp: fix _CBM_CFS pin directions

2011-04-26T10:43:53+00:00

The current davinci_mcasp_set_dai_fmt() sets bits ACLKX and ACLKR in the PDIR
register for the codec clock-master/frame-slave mode; however, this results in
the ACLKX and ACLKR pins being outputs according to SPRUFM1 [1]  which
conflicts with "codec is clock master."

Similarly to the previous patch in this series, "fix _CBM_CFS hw_params" --
For codec clock-master/frame-slave mode (_CMB_CFS), clear bits ACLKX and ACLKR
in the PDIR register to set the pins as inputs and hence allow externally
sourced bit-clocks.

davinci-mcasp: fix _CBM_CFS hw_params

2011-04-26T10:43:38+00:00

The current davinci_mcasp_set_dai_fmt() sets bits ACLKXE and ACLKRE (CLKXM
and CLKRM as they are reffered to in SPRUFM1 [1]) for codec clock-slave/
frame-slave mode (_CBS_CFS) which selects internally generated bit-clock and
frame-sync signals; however, it does the same thing again for codec
clock-master/frame-slave mode (_CBM_CFS) in the very next case statement which
is incorrectly selecting internally generated bit-clocks in this mode.

For codec clock-master/frame-slave mode (_CBM_CFS), clear bits ACLKXE and
ACLKRE to select externally-generated bit-clocks.

davinci-mcasp: use bitfield definitions for PDIR

2011-04-26T10:43:29+00:00

The current driver creates value for set/clr of PDIR using (x<<26) instead
of the #defines that are convieniently made available.

Update the driver to use the bitfield definitions of PDIR. There is no
functional change introduced by this patch.

ASoC: davinci-mcasp: correct tdm_slots limit

2011-04-26T10:43:19+00:00

The current check for the number of tdm-slots specified by platform data is
always true (x >= 2 || x <= 32); therefore the else branch that warns of an
incorrect number of slots can never be taken.

Check that the number of tdm slots specified by platform data is between 2
and 32, inclusive.

asoc: davinci_voicecodec: use mfd_data instead of driver_data

2011-03-23T09:41:56+00:00

Use mfd_data for passing information from mfd drivers to soc
clients.  The mfd_cell's driver_data field is being phased out.

Clients that were using driver_data now access .mfd_data
via mfd_get_data().
