Although the McASP supports sign-extending samples in RX or TX [1]; the davinci-mcasp driver does not touch the {R,X}PBIT or {R,X}PAD field of the {R,X}FMT registers meaning that the McASP will serialize the bytes it is given regardless of their signedness. So supporting unsigned formats is as simple as adding them to the metadata of the davinci-mcasp driver. Update the FMTBITs reported in the snd_soc_dai_driver and also update the case statements in davinci-mcasp's hw_params() function so that the McASP can be connected to CODECs that use unsigned values.

'struct of_device' no longer exists, and its functionality has been merged into platform_device. Update the MPC5200 audio DMA driver (mpc5200_dma) accordingly. This fixes a build break. Signed-off-by:

Board file support for Ventana is not yet mainlined, and probably won't ever be given the move to Device-Tree. Consequently, the Ventana entry is being removed from arch/arm/tools/mach-types in the next merge window, since it was registered over a year ago. This will also remove function machine_is_ventana(), which is used by the ASoC Tegra WM8903 machine driver. This will cause compilation failures. Drop Ventana support to resolve this. Hopefully, in the not-too-distant future, tegra_wm8903.c will be able to configure itself from Device-Tree, and hence we'll be able to re-instate Ventana support just by creating a .dts file for the board. Also note that Aebl support is in a similar boat. However, that board isn't scheduled for deprecation for at least another 5 months, and perhaps we will have completely removed non-Device-Tree support from tegra_wm8903.c by then and/or adjusted mach-types policy.

Move the test on pdev->id before the kzalloc to avoid requiring kfree when the test fails. This fix was suggested by Wolfram Sang. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ identifier x; expression E1!=0,E2,E3,E4; statement S; iterator I; @@ ( if (...) { ... when != kfree(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 kfree(x); ... return ...; } ) // </smpl> Signed-off-by:

Saif needs clear clk gate first before writing registers or the write will not success. The original xx_get_mclk function clear clk gate after mclk setting that may cause the former mclk setting unwork, then the real output mclk maybe inaccurate. Placing the clear before setting mclk to avoid such an issue. We also have to clear clk gate in startup instead of in prepare function. Signed-off-by:

The first change is to add an of_node_put, since codec_np has previously been allocated. The rest of the patch reorganizes the error handling code so the only code executed is that which is needed.

of_parse_phandle increments the reference count of np, so this should be decremented before trying the next possibility. Since we don't actually use np, we can decrement the reference count immediately. Reported-by:

The WM8962 features a DSP providing a number of signal processing features including HD Bass and Virtual Surround Sound (VSS). Enable initial support for this, allowing users to enable and disable the algorithms using the default coefficient sets.

This occurs frequently if we are in edge triggered mode as we must poll the interrupt status register until we get no more interrupts so it's worth the effort - it means we skip writing null acknowledgements to the chip. Signed-off-by:

This patch includes below small fixes: 1. Move sta32x_set_bias_level() from sta32x_i2c_remove() to sta32x_remove(). 2. Remove a redundant regulator_bulk_free() call in sta32x_i2c_remove(), as we will call regulator_bulk_free() in sta32x_remove(). 3. Remove unneeded snd_soc_codec_set_drvdata(codec, NULL) in sta32x_i2c_remove. The i2c core will set the clientdata to NULL. Signed-off-by:

The ASoC core tries to not enforce symmetric rates when two streams open simultaneously. It does so by checking rtd->rate being zero. This works exactly once after booting because it is not set to zero again when the streams close. Fix this by setting rtd->rate when no active stream is left. [This leads to lots of warnings about not enforcing the symmetry in some situations as there's a race in the userspace API where we know we've got two applications but don't know what rates they want to set. -- broonie ] Signed-off-by:
