ASoC: fix au1x platform

2010-08-31T12:06:31+00:00

This patch fixes up the au1x audio platform after the multi-component
merge:
- compile fixes and updates to get DB1200 platform audio working again,
- removal of global variables in AC97/I2S/DMA(PCM) modules.

The AC97 part is limited to one instance only for now due to issues
with getting at driver data in the soc_ac97_ops.

MIPS: Alchemy: fix deprecated compile warnings

2010-08-05T12:25:46+00:00

Replace deprecated DMA_32BIT_MASK with DMA_BIT_MASK.  This is needed because
the new style platform makefiles will enable -Werror.

MIPS: DB1200: PCMCIA card detection must not be auto-enabled.

2010-04-30T19:52:43+00:00

Same issues as SD card detection:  One of both is always triggering and the
handlers take care to shut it up and enable the other.  To avoid messages
about "unbalanced interrupt enable/disable" they must not be automatically
enabled when initally requested.

This was not an issue with the db1200_defconfig due to fortunate timings;
on a build without network chip support the warnings appear.

MIPS: Alchemy: DB1200: Remove custom wait implementation

2010-04-12T16:26:22+00:00

While playing with the out-of-tree MAE driver module, the system would
panic after a while in the db1200 custom wait code after wakeup due to
a clobbered k0 register being used as target address of a store op.

Remove the custom wait implementation and revert back to the Alchemy-
recommended implementation already set as default.

MIPS: Alchemy: use 36bit addresses for PCMCIA resources.

2010-02-27T11:53:43+00:00

On Alchemy the PCMCIA area lies at the end of the chips 36bit system bus
area.  Currently, addresses at the far end of the 32bit area are assumed
to belong to the PCMCIA area and fixed up to the real 36bit address before
being passed to ioremap().

A previous commit enabled 64 bit physical size for the resource datatype on
Alchemy and this allows to use the correct 36bit addresses when registering
the PCMCIA sockets.

This patch removes the 32-to-36bit address fixup and registers the Alchemy
demo board pcmcia socket with the correct 36bit physical addresses.

Tested on DB1200, with a CF card (ide-cs driver) and a 3c589 PCMCIA ethernet
card.

MIPS: Alchemy: get rid of common/reset.c

2010-02-27T11:53:04+00:00

Implement reset / poweroff in the board code instead.  The peripheral reset
code is gone too since YAMON which all in-tree boards use does the same
work when it boots.

MIPS/SOUND: Alchemy: DB1200 AC97+I2S audio support.

2010-02-27T11:53:01+00:00

Machine driver for DB1200 AC97 and I2S audio systems, intended as a proper
reference asoc machine for Alchemy-based systems.  AC97/I2S can be selected
at boot time by setting switch S6.7.
