2018-12-18ASoC: ti: Merge davinci and omap directoriesPeter Ujfalusi1-541/+0
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.

2018-11-23ASoC: omap-dmic: Add pm_qos handling to avoid overruns with CPU_IDLEPeter Ujfalusi1-0/+9
We need to block sleep states which would require longer time to leave than the time the DMA must react to the DMA request in order to keep the FIFO serviced without overrun.

2013-11-24ASoC: omap: mcbsp, mcpdm, dmic: raw read and write endian fixVictor Kamensky1-2/+2
All OMAP IP blocks expect LE data, but CPU may operate in BE mode. Need to use endian neutral functions to read/write h/w registers. I.e instead of __raw_read[lw] and __raw_write[lw] functions code need to use read[lw]_relaxed and write[lw]_relaxed functions. If the first simply reads/writes register, the second will byteswap it if host operates in BE mode. Changes are trivial sed like replacement of __raw_xxx functions with xxx_relaxed variant.

2013-08-20ASoC: omap: simplify platform_get_resource_byname/devm_ioremap_resourceJulia Lawall1-6/+3
Remove unneeded error handling on the result of a call to platform_get_resource_byname when the value is passed to devm_ioremap_resource. In the case of omap-dmic.c, the error-handling code of devm_ioremap_resource is also corrected to include releasing the clock. A simplified version of the semantic patch that makes this change is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ expression pdev,res,e,e1; expression ret != 0; identifier l; @@ res = platform_get_resource_byname(...); - if (res == NULL) { ... \(goto l;\|return ret;\) } e = devm_ioremap_resource(e1, res); // </smpl> Signed-off-by: Julia Lawall <Julia.Lawall@lip6.fr> Acked-by: Jarkko Nikula <jarkko.nikula@bitmer.com> Signed-off-by: Mark Brown <broonie@linaro.org>

The DMA resource no longer available via this API when booting with DT. DMIC is only available on OMAP4/5 and both can boot with DT only.
