2016-06-02ASoC: davinci-mcasp: Use a copy of pdata per instance during DT bootPeter Ujfalusi
Instead of modifying the static pdata struct per McASP instance we need to allocate pdata for each McASP. This way we can avoid configuration leakage from prior McASP to McASP drivers probed at later time.

2016-06-02ASoC: davinci-mcasp: Fix dra7 DMA offset when using CFG portPeter Ujfalusi
The TX and RX offset is different for each serializers when using the CFG port for DMA access. When using the CFG port only one serializer can be used per direction so print error message and only configure the first serializer's offset.

2016-05-09ASoC: davinci-mcasp: Calculate AUXCLK divider when setting up master clocksPeter Ujfalusi
If the McASP is used as clock master and the reference clock is AUXCLK we can have additional level of divider. The BCLK divider is limited to maximum 32, if the desired bclk can not be reached with this, the AUXCLK divider also needs to be used.

Fixes the associations between the tx_mask and rx_mask and the associated playback / capture streams during setting of the TDM slot. With this patch in place it is now possible for example to only populate tx_mask (leaving rx_mask as 0) for output-only codecs to control the TDM slot(s) the McASP serial port uses for transmit. Before that, this scenario would incorrectly rely on the rx_mask for this.

2015-06-08ASoC: davinci-mcasp: Logic low for inactive output slotsMisael Lopez Cruz
The default state when serializers are in inactive slots is Hi-Z. In some cases, there are no additional components driving the data lines to a safe state so they might have noise. While in inactive slots, the McASP AXR pins configured as outputs can be driven low through the serializer pin drive mode setting (DISMOD) to prevent such noise.

Set channel count constraints for multiple serializers case. On McASP the active channels mask is the same for all the serializers.

2015-04-30ASoC: davinci-mcasp: Calculate BCLK using TDM slots and remove channels ruleJyri Sarha
The McASP driver currently always sends as many slots or channels to a i2s-wire as there are configured tdm_slots (see mcasp_i2s_hw_param()).

The dapm field of the snd_soc_codec struct will eventually be removed (replaced with the DAPM context from the component embedded inside the CODEC). Replace its usage with the card's DAPM context. The idea is that DAPM is hierarchical and with the card at the root it is possible to access widgets from other contexts through the card context.

2015-03-24ASoC: davinci-mcasp: Set rule constraints if implicit BCLK divider is usedJyri Sarha
Set rule constraints to allow only combinations of sample-rate, sample-format, and channels counts that can be played/captured with reasonable sample-rate accuracy. The logic with tdm-slots and serializers (=i2s data wires) goes like this: The first wire will take all channels up to number of tdm-slots, before following wires (if any) are used. If the first wire is used fully, the remaining wires share the same clocks and the divider can be calculated for the first wire. Also, takes the number of tdm-slots into account when implicitly selecting the BLCK divider.
