ASoC: omap: Introduce the generic_dmaengine_pcm based sdma-pcm With the generic dmaengine_pcm support the omap-cpm can be replaced with a much smaller wrapper. CPU DAI drivers can use the: int sdma_pcm_platform_register(struct device dev, char txdmachan, char *rxdmachan); To register the platform driver, txdmachan/rxdmachan is only needed to be provided if the DMA channel names are not standard tx/rx, like in case of McPDM, or the DAI is only capable of one audio direction (DMIC, HDMI). This patch only introduces the source file and changes to the Kconfig/Makefile, but does not change any of the DAI drivers to use it.

ASoC: omap: Replace HTTP links with HTTPS ones Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w\|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

ASoC: ti: Merge davinci and omap directories Create new directory to contain all Texas Instruments specific DAI, platform and machine drivers instead of scattering them under davinci and omap directories. There is already inter dependency between the two directories becasue of McASP (on dra7x it is serviced by sDMA, not EDMA). With the upcoming AM654 we will need to introduce new platform driver for UDMA and it does not fit under davinci, nor under omap. With the move I have restructured the Kconfig to be more usable in the era of simple-sound-card: CPU DAIs can be selected individually and they will select the platform driver they can be served with. To avoid breakage, I have moved over deprecated Kconfig options so defconfig builds will work without regression.
