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 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.

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.

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.

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.
