The currently available FIFO modes (mode1 and mode7) require master mode from the codec. Do not allow the slave configuration when the FIFO is in use. Signed-off-by:

Mode 7 of tlv320dac33 operates in the following way: The codec is in master mode. Host configures upper and lower thresholds in tlv320dac33 During playback the codec will clock in the data until the upper threshold is reached in FIFO. At this point the codec stops the colocks on the serial bus. When the FIFO fill is reaching the lower threshold limit the codec will enable the clocks on the serial bus, and clocks in data till the upper threshold is reached. In this mode, we can also request interrupts for threshold events (upper, lower and alarm), which could be used for power management. At this point the interrupts are not enabled for this mode, but it can be taken into use in the future, when the surrounding code makes it possible to use it. Signed-off-by:

Use switch instead of if statements to configure FIFO bypass and mode1. With this change adding new FIFO mode is going to be easier, and cleaner. Signed-off-by:

Ensure that the code is going to be readable, when new FIFO modes are introduced later. Move the prefill and playback state handling to inlined functions. Signed-off-by:

In order to have support for more FIFO modes supported by tlv320dac33, the switch for enabling/disabling the FIFO use has to be replaced with an enum. Signed-off-by:

PM architecture of ad1938 is simple, we don't need a bundle of functions like ad1938_pll_powerctrl, ad1938_set_bias_level for only PLL. A dapm supply will handle on/off of PLL. Since soc-core can poweron/off PLL on-demand, we don't need to poweron/off PLL in suspend/resume entries too. Signed-off-by:

Tests show frequent suspend/resume(frequent poweroff/on ad1836 internal components) maybe make ad1836 clock mode wrong sometimes after wakeup. This patch reset/restore ad1836 clock mode while executing PM, then ad1836 can always resume to right clock status. Signed-off-by:

The WM8955 is a low power, high quality stereo DAC with integrated headphone and loudspeaker amplifiers, designed to reduce external component requirements in portable digital audio applications. This is an initial driver implementing support for the majority of the functionality in the device, currently OUT3 is not supported. Signed-off-by:

The driver can be 'generalized' a bit by not hardcoding '2'(the number of I2Sv3 controllers that the driver can handle) at many places, instead we define a macro for it. That makes it easier to increase number of controllers by changing the parameter at just one place, this will be useful when there is support for newer SoCs, which have the same controller, only more in number.

sizeof(codec->reg_cache) is just the size of the pointer. Elsewhere in the file, codec->reg_cache is used with sizeof(wm8900_reg_defaults), so the code is changed to do the same here. A simplified version of the semantic patch that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression *x; expression f; type T; @@ *f(...,(T)x,...) // </smpl> Signed-off-by:

There are build errors when building for some of the omap2/3 boards without enabling sound: sound/built-in.o:(.data+0x43bc): undefined reference to `soc_codec_dev_tlv320aic23' sound/built-in.o:(.data+0x43cc): undefined reference to `tlv320aic23_dai' Confused me quite a bit since the drivers that had references to the codec weren't enabled. Turns out the Makefile was using the wrong config option to enable them. Patch below. Reported-by:

Add clock enable and disable calls to resume and suspend respectively. Also add a member to the audio device data structure which tracks the clock status. Tested on DA850/OMAP-L138 EVM. For the purpose of testing, the patches[1] which add suspend-to-RAM support to DA850/OMAP-L138 SoC were applied.
