From 71f6e0645be42f93c0f90dfcc93b9d2d277c2ee6 Mon Sep 17 00:00:00 2001 From: Kuninori Morimoto Date: Wed, 2 Dec 2009 15:11:08 +0900 Subject: ASoC: sh_fsi: avoid using global variable Current FSI driver use global variable to access device data. But this style will be broken if SuperH come with multiple FSI blocks in future. To solve this problem, this patch use cpu_dai->private_data.

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.

At startup time, call snd_soc_dai_set_sysclk() with 0 as 'freq' argument so it offers all the sample rates. Later, the function is called again to give proper constraints. Use the external audio clock generator to provide double data rate clocks as the PXA's internal baud generator does anything but what's described in the datasheets.

This driver replaces it. It works in DMA mode on i.MX21/27 and using an FIQ handler on other systems. It also supports AC97 mode of the SSI units.

The BCLK divider changes the actual speed of the serial bus in burst mode, which is faster than the sampling frequency of the running stream. In this way platforms can experiment with the optimal burst speed without the need to modify the codec driver itself.

With older mobile CODECs this is required since the outputs are referenced to a non-zero voltage and enabling or disabling this voltage without audible pops or clicks in the output takes too long to do when starting or stopping audio. As a result of features such as ground referenced outputs and class D speaker drivers current generation devices are able to power on and off much more quickly without these system level issues so provide a new flag idle_bias_off in snd_soc_codec which will cause the core to turn off the CODEC bias. The distinction between STANDBY and OFF is still maintained. This is partly for consistency but also allows for potential future extensions such as per-machine overrides or deferring the bias removal.

Support for interfacing with ABE will be added later. McPDM dai currently supports up to 4 downlink channels and 2 uplink channels simultaneously, as well as 88.2 and 96 KHz, and a sample size of 32 bits.

This means that any clock mismatch between the CPU and the audio subsystem can result in the status reported to applications drifting away from the actual status of the hardware. This is particularly likely at present since the SSI driver is only capable of operating in slave mode so it's very likely that the interface will be clocked from a different source. Instead check the offset reported by the FIQ and only notify when we have transferred at least one period, re-firing the timer if we didn't do so. Also factor out the calculation of the timer expiry time for make it a bit easier to experiment with. Note that this only improves the situation, problems can still be triggered.
