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. 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 != of_node_put(x) when != x = E3 when != E3 = x * return ...; } ... when != x = E2 when != I(...,x,...) S if (...) { ... when != x = E4 of_node_put(x); ... return ...; } ) // </smpl> Signed-off-by:

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. Further patches will add support for runtime configuration of the DSP coefficients. Signed-off-by:

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:

For non-audio uses like accessory detection we can use a lower quality, unregulated microphone bias, saving a little power. As the hardware can manually enable and disable the biases we can select regulating mode automatically with supply widgets connected to the biases. 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:

The PowerPC Freescale SSI driver is claiming the IRQ when the IRQ when the device is opened, which means that the /proc/interrupts entry for the SSI exists only during playback or capture. This also meant that the user won't know that the IRQ number is wrong until he tries to use the device. Instead, we should claim the IRQ when the device is probed. Signed-off-by:

Currently it is only possible to route one source per switch into a mixer. This patch modifies the code, so that it is possible to route multiple sources into a mixer via the same switch. One use-case for this is routing a stereo channel pair into a mono-mixer via the same switch. Signed-off-by:

Pull control is availalbe for WM8994 AIF2, generally disabled as part of the GPIO configuration in order to save power after system startup. As on newer devices in the series there is no GPIO functionality on these pins this will happen less naturally so have the driver disable the pulls as the AIF is probed. Signed-off-by: -
