Devices that need this exist; obviously the newer regmap defaults mechanism will deal with this more happily. Signed-off-by:Mark Brown <broonie@opensource.wolfsonmicro.com>

Currently the condition for these WARN_ONs is reversed and they are placed before the actual check whether we are going to write to that register. So if the codec implements the register_writable callback we'll get a warning for each writable register when syncing the register cache. While we are at it change the check to use snd_soc_codec_writable_register instead of open-coding it. Signed-off-by:

Change the default return value of snd_soc_codec_{readable,writable}_register to true when no codec specific callback for this function is given. Otherwise all registers of that codec will neither be readable nor writable, which is most certainly not what we want. Signed-off-by: -

If the channel is allocated as writecombine, then mmaping it should also use writecombine. Also, add a proper device for the call. Ported from a similar fix for mach-mxs. Signed-off-by:

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.

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,...)

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:
