This driver used the wrong OF-helper when looking up the optional
capture-codec child node during probe. Instead of searching just
children of the sound node, a tree-wide depth-first search starting at
the unrelated platform node was done. Not only could this end up
matching an unrelated node or no node at all; the platform node could
also be prematurely freed since of_find_node_by_name() drops a reference
to its first argument. This particular pattern has been observed leading
to crashes after probe deferrals in other drivers.

Fix this by dropping the broken call to of_find_node_by_name() and
keeping only the second, correct lookup using of_get_child_by_name()
while taking care not to bail out if the optional node is missing.

Note that this also addresses two capture-codec node-reference leaks
(one for each of the original helper calls).

Compile tested only.

This fix a bug in dapm_widget_power_read_file(),
where it may sent opposite order of source/sink widget
into the p->connected().

for example,
static int connected_check(source, sink);
{"w_sink", NULL, "w_source", connected_check}

the dapm_widget_power_read_file() will query p->connected()
in following case
	p->conneted("w_source", "w_sink")
	p->conneted("w_sink", "w_source")
we should avoid the last case, since it's the wrong order (source/sink)
as declared in snd_soc_dapm_route.

The soc_compr_copy callback is currently broken. Since the
changes to move the compr_ops over to the component the return
value is not correctly propagated, always returning zero on
success rather than the number of bytes copied. This causes
user-space to stall continuously reading as it does not believe
it has received any data.

Furthermore, the changes to move the compr_ops over to the
component iterate through the list of components and will call
the copy callback for any that have compressed ops. There isn't
currently any consensus on the mechanism to combine the results
of multiple copy callbacks.

To fix this issue for now halt searching the component list when
we locate a copy callback and return the result of that single
callback. Additional work should probably be done to look at the
other ops, tidy things up, and work out if we want to support
multiple components on a single compressed, but this is the only
fix required to get things working again.

For certain platforms, it is required to start the clocks (mclk/sclk/fs)
before the stream start. Example: for few chrome systems, codec needs the
mclk/sclk to be enabled early for a successful clock synchronization and
for few IVI platforms, clock need to be enabled at boot and should be ON
always.

Add the required structures and create set_dma_control ipc to enable or
disable the clock. To enable sclk without fs, mclk ipc structure is used,
else sclkfs ipc structure is used.

Clock prepare/unprepare are used to enable/disable the clock as the IPC
will be sent in non-atomic context. The clk set_dma_control IPC
structures are populated during the set_rate callback and IPC is sent
to enable the clock during prepare callback.

This patch creates virtual clock driver, which allows the machine driver
to use the clock interface to send IPCs to DSP to enable/disable the
clocks.

Commit 3bb0f7c3 ("ASoC: don't use snd_soc_write/read on twl4030")
caused regressions for both twl4030 and twl6040 as it assumes the
ASoC driver is using regmap. As a side effect, this also causes a
considerable increase in idle power consumption omap3 boards using
twl4030 as the PMIC.

This is because the removal of read and write function pointers
causes some of the ASoC IO functions to not do anything. For example,
snd_soc_register_card() calls snd_soc_dapm_new_widgets() that calls
snd_soc_codec_drv_read() that now does nothing.

A long term solution suggested by Mark Brown <broonie@kernel.org>
is to make the twl drivers use regmap by adding a call to
snd_soc_codec_set_regmap(). This however needs more consideration
as currently the driver internal reads do caching and we would have
both regmap access and internal read/write access accessing the same
hardware registers.

So to fix the regression, let's just do a partial revert adding back
the read and write function pointers. Note that other non-regmap
ASoC drivers may need similar patches.

Power Down Release Command (PMVR, PMDAC, RSTN, PMDA1-PMDA6)
which are located on PW_MGMT1 / PW_MGMT3 register must be
write again after at least 5 LRCK cycle or later on each command.
Otherwise, Playback volume will be 0dB.
Basically, it should be

        1.   PowerDownRelease by Power Management1 <= call 1.x after 5LRCK
        1.x  Dummy write      to Power Management1
        2.   PowerDownRelease by Power Management3 <= call 2.x after 5LRCK
        2.x  Dummy write      to Power Management3

To avoid too many dummy write, this patch is merging these.

        1.   PowerDownRelease by Power Management1
        2.   PowerDownRelease by Power Management3   <= call after 5LRCK
        2.x  Dummy write      to Power Management1/3 <= merge dummy write

If bcm2835 is configured as bitclock master calling hw_params()
after prepare() fails with EBUSY. This also makes it impossible to
use bcm2835 in full duplex mode.

The error is caused by the split clock setup: clk_set_rate
is called in hw_params, clk_prepare_enable in prepare. As hw_params
doesn't check if the clock was already enabled clk_set_rate
fails with EBUSY.

Fix this by moving clock startup from prepare to hw_params and
let hw_params properly deal with an already set up or enabled
clock.
