The WM8741 is a very high performance stereo DAC designed for audio applications such as professional recording systems, A/V receivers and high specification CD, DVD and home theatre systems. The device supports PCM data input word lengths from 16 to 32-bits and sampling rates up to 192kHz. The WM8741 also supports DSD bit-stream data format, in both direct DSD and PCM-converted DSD modes. TODO: Expand wm8741_set_dai_sysclk and rate_constraint members to allow for all supported sample rate / Master Clock frequency combinations. Fully enable control of supplies.

The use of sDMA packet mode in THRESHOLD mode removes the restriction on the period size. With the extended THRESHOLD mode user space can ask for any period size it wishes, and the driver will configure the sDMA and McBSP FIFO accordingly. Replace the hw_rule for the period size with static constraint, which will make sure that the period size will be always even (to avoid prime period size, which could be possible in mono stream) Signed-off-by: NPeter Ujfalusi <peter.ujfalusi@nokia.com> Acked-by: NJarkko Nikula <jhnikula@gmail.com> Acked-by: NMark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: NLiam Girdwood <lrg@slimlogic.co.uk>

Utilize the sDMA controller's packet syncronization mode, when the McBSP FIFO is in use (by extending the THRESHOLD mode). When the sDMA is configured for packet mode, the sDMA frame size does not need to match with the McBSP threshold configuration. Uppon DMA request the sDMA will transfer packet size number of words, and still trigger interrupt on frame boundary. The patch extends the original THRESHOLD mode by doing the following: if (period_words <= max_threshold) Current THRESHOLD mode configuration Otherwise (period_words > max_threshold) McBSP threshold = sDMA packet size sDMA frame size = period size With the extended THRESHOLD mode we can remove the constraint for the maximum period size, since if the period size is bigger than the maximum allowed threshold, than the driver will switch to packet mode, and picks the best (biggest) threshold value, which can divide evenly the period size.

Platform parameter to enable automatic FIFO configuration when the codec is in Mode1 or Mode7 FIFO mode. When this mode is selected, the controls for changing nSample (in Mode1), and UTHR (in Mode7) are not added. The driver configures the FIFO configuration based on the stream's period size in a way, that every burst will read period size of data from the host. In Mode7 we need to use a formula, which gives close enough aproximation for the burst length from the host point of view.

When digital microphones are connected to twl, delay is needed after enabling the digimic interface of the codec. Add new parameter for the setup data, which can be used to pass the apropriate delay in ms after the digimic interface has been enabled. Without certain delay (in certain HW configuration) the beggining of the recorded sample contains a glitch, which is generated by the digital microphones. Delaying the micbias1, 2 (which is the bias for the digimic0 or 1) does not help, since the glitch is coming after switching the digimic interface. Reversing the micbias and digimic enable order does not work either (in that case the wait need to be added after the micbias enabled).

AIF1ADC TDM mode has no effect other than causing the ADCDAT line to be tristated rather than driven low on clock cycles where there is no data to be transmitted. If the clock cycle is idle then there should be no devices using the data so tristating should have no adverse effects.

Currently the EDMA queue to be used by for servicing ASP through internal RAM is fixed to EDMAQ_0 and that to service internal RAM from external RAM is fixed to EDMAQ_1. This may not be the desirable configuration on all platforms. For example, on DM365, queue 0 has large fifo size and is more suitable for video transfers. Having audio and video transfers on the same queue may lead to starvation on audio side. platform data as defined currently passes a queue number to the driver but that remains unused inside the driver. Fix this by defining one queue each for ASP and RAM transfers in the platform data and using it inside the driver. Since EDMAQ_0 maps to 0, thats the queue that will be used if the asp queue number is not initialized. None of the platforms currently utilize ping-pong transfers through internal RAM so that functionality remains unchanged too.
